There are also different options as to which lines Crossrail 2 will serve, mainly those that are currently part of the South West Trains network. No options - but a suggestion of 4tph (peak) to each of \Hampton Court, Chessington, Shepperton and Eposm, with an extra 2tph on the latter two from waterloo (presumably to Dorking and back to waterloo via Twickenham respectively). A further 2tph to Hampton Wick (!?) and a further 2tph unallocated. The Balham Bulge looks even more ludicrous than the Tooting Twist.

As well as an option to go via Wood Green instead of Turnpike Lane and Alexandra Palace. There are also different options as to which lines Crossrail 2 will serve, mainly those that are currently part of the South West Trains network. To be strictly accurate the route via Balham is an option as it's not safeguarded. Geological issues at Tooting Broadway would require a different construction methodology and take 2 years longer. Wandsworth Council favour the Tooting alignment so CR2 / TfL may have problems in trying to adopt Balham. Could also get interesting given a certain Mayoral candidate and which seat he represents in Parliament. The peak service pattern seems to be 12 tph to Broxbourne 15 tph to New Southgate 3 tph starting / ending at T Hale 30 tph through the core 4 tph (or possibly 6 on some) on the SW branches 14 or 10 tph terminating / starting at Wimbledon. No clues as to how destinations would be paired although I'd not be surprised to see the 3 tph from T Hale go no further than Wimbledon. The scale of the worksite at New Southgate is massive - it'd be both sides of the A406 and stretching a long way north because of the need for a depot and sidings. The construction impacts are also considerable in a number of locations. If CR2 goes ahead Victoria will have been a building site for the better part of 20 years (after the current LU works and other office developments complete in 2-3 years time).

What an absolute mess! The whole thing is just utterly messy. How do they expect to run 30tph with the amount of inter-running and junctions the thing will encounter both north and south of the river? The kinks reduce it something on par with some of the fantasy threads and are just an obvious clue as to project creep and political greasing. Not to mention the bizarre amount of nearly-but-not-quite duplication north of Angel.

I think the service pattern looks quite complicated with the amount of branches in North and South London, compared to the slightly simpler route of Crossrail 1. I haven't looked at all the factsheets yet , but how will they reverse trains at Wimbledon and Tottenham Hale without disrupting other services? It's as if Crossrail 2 is trying to be a mix of high frequency metro services as well as a less frequent outer-suburban service.

It's as if Crossrail 2 is trying to be a mix of high frequency metro services as well as a less frequent outer-suburban service. Your final sentence sums up the paradox of how London is approaching Crossrail type lines. They are an inevitable compromise which means they're neither one thing or the other. They have to run at almost Metro type frequencies in the central area in order to add capacity but the further you go out the harder it gets to run services at 2 min headways. You can argue that's no different from the longer tube lines because they have multiple branches and also turn trains closer to the centre. It all boils down to what is economic. One of my problems is that the "hype" is all about the core level of service which then misleads people to expect the same at Chessington or Shenfield or Maidenhead. The reality is that none of those places will ever get really high frequency services. With Crossrail 1 people are still going to be waiting 10 mins for a Shenfield train off peak or 6-8 mins for an Abbey Wood train. How does that compare to a Jubilee Line train from Canary Wharf that's probably twice as frequent as that off peak. It's no different from now for Shenfield line passengers. Clearly there will be other advantages with new trains, upgraded or new stations and hopefully quick journey times. I assume that additional infrastructure will be put in place at T Hale and Wimbledon. Wimbledon is clearly going to see a massive rebuild with large parts of shopping centres having to be demolished. There's no clarity as to what will happen north of T Hale - presumably because it's not clear what the 4 tracking scheme will look like. I'm a tiny bit sceptical as to whether there is now enough land for a 4 track alignment *and* some sort of turnback facility. On the assumption the slow lines are on the outside then it's even harder to see how you can turn 3 tph if they have to cross the fast tracks which will have a high peak frequency. I suppose they might do something clever with dive unders to remove conflicts?

With the advent of the New Spurs ground of 60k+ and being used for the NFL games, why hasn't someone had a lightbulb moment and suggsted extending it to Northumberland Park? either that or putting in a island platform at the side of the Depot for the Victoria line? After all it happened with CR1 when they realised it would be a great idea to move the West terminal from Maidenhead to Reading, logical and better for interchange. Still i am not paid 40k a year to examine my navel fluff and not see the bleeding obvious.

Look at a map of the proposed line. Perhaps your navel fluff is in need of attention?

Given my username it should come as no surprise that my principal interest will be the service levels on the Kingston branch, but they don't seem to make any sense. Noting that the existing service levels are peak frequencies, as they include the 2tph on the Shepperton branch that run via Richmond and the two extra services that run round the loop from Twickenham (on top of the all-day 2tph all the way round). Equally evidently, the figures cannot include the rounders going the long way round from Kingston, as the total would then be eight. What we see post XR2 is an extra two from Shepperton, including two to Waterloo. If these two still go via Richmond, there will be 4tph from Shepperton via Kingston to Crossrail. But there will be 6-8 Crossrail services from Kingston. Where will the others start from? (all we are told is "not Twickenham"!) The four to Waterloo are presumably the existing four peak hour services from Twickenham or beyond.

It would be useful to see a map of the current options and route against all other railways and stations. Perhaps it would help highlight some of the duplication going on.
Now the routing of the tooting/balham options have been defined, is anyone else thinking that the curves required seem dubious for either?

Ben - there is an interactive scalable map on the CR2 consultation page. It shows the route alignment placed on a street map that shows other rail routes, parks, streets etc. It does NOT show tube line alignments but I suspect many people on here know broadly where they run so that's not insurmountable.

I haven't looked at all the factsheets yet , but how will they reverse trains at Wimbledon and Tottenham Hale without disrupting other services? It's as if Crossrail 2 is trying to be a mix of high frequency metro services as well as a less frequent outer-suburban service. Actually it is not as bad as you think, pricipall because the LACK of junctions on the northern branches. Firstly the New Southgate branch will be physically segregated from the ECML so as with the Abbey Wood branch of Crossrail 1, if the core timetable starts being delayed it doesn't cause too many issues in service terms (particularly with the depot to send trains into if there is a need to send trains out of the way while service recovery is underway). Secondly the Broxbourne branch sounds as though it will operate very much along the lines of Crossrail 1s Shenfield branch - i.e. just as the tracks Crossrail 1 uses there will be relatively segregated from other GEML services, it sounds as if the Crossrail 2 tracks in the Lea Valley will be relatively segregated from WAML services. Again this arrangement means that the need to hit precise timings at junctions or the ability to recover from issues is much easier than on the South West legs (see below) The big issue comes with the South Western leg where services will need to share tracks and junctions with residual SWT services to Sheperton, services round the Kingston loop, stopping services to Woking and services to Dorking / Guildford via Epsom. In many respects this has similarities with Crossrail 1 when the western leg joins the GWML - OK there aren't as many branches, but the GWML relief lines carry quite a lot of freight traffic from Reading to Acton yard (very different from the crossing moves at Forest Gate in planning terms, plus there will still be residual GW services into Paddington using them too. Therefore in service planning terms, it is the South Western section that has the biggest potential to screw things up and therefore is what the timetable will have to be developed from. What happens on the Southgate / Broxbourne branches simply follows in from that but given their self contained nature they are actually a good way of doing things. By contrast, consider Thameslink - it has to mesh with 3 main line timetables north and south of the river, has a critical at grade junction in the core, shares tracks with InterCity, freight, London suburban services, etc. The potential for timetable disruption is immense. Crossrail plays it safer by restricting itself to Shenfield and Reading - with the Abbey Wood branch being entirely self contained and Crossrail 2 continues this theme.

Having been to a presentation on this, it appears that 10 or 12 x 12-car tph are being planned along the Lea Valley line, and that the quadrupling might be concluded by 2025, well ahead of the tunnelling. Prior to the big hole opening; early 30s, there would be a shortage of terminating points in London, so Stratford, even Chingford etc might come into play. I wonder if anyone has thought of relaying Tottenham N Jc-South Tottenham- so these trains could run back via Seven Sisters? All level crossings would have to be replaced by bridges, the ground being unsuitable for underpasses. This would mean demolition of premises nearby. Most stations rebuilt. 12000 seats per hour would be a massive stimulus for the Lea Valley and would revolutionise the settlement pattern in places like Broxbourne, Waltham Abbey, Cheshunt etc. It would be a case of infrastructure preceding building such as we have not seen since the 1930s and in the same area, the GER Edwardian Churchbury and Fairlop loops, which were so unsuccessful at first. Land for a depot is being earmarked at the site of the old CEGB Rye House sidings, but curiously, no station is planned at Hoddesdon, the major town in the area.
Nazeing would be a good place to buy a house, folks. Near the line but far from any demolitions!

....... but curiously, no station is planned at Hoddesdon, the major town in the area. Nazeing would be a good place to buy a house, folks. Near the line but far from any demolitions! The problem with a station at Hoddesdon is that it is too close to Broxbourne and Rye house, also the line does not pass near Hoddesdon town centre, but goes past the edge of the town which would be another setback. There is also the junction where the Hertford line branches off from the Cambridge line, which is close to Broxbourne station as another hurdle that would be have to be overcome. And all this is before you think about the non stop Stanstead Express service that currently overtakes these trains at Broxbourne and is due to get an improved service too. Moving on to Nazeing, I used to live there. It's already too expensive to buy a house there as it's got a village feel, but it close to Broxbourne for the train, Waltham Abbey for the M25 and Harlow for shops so is very well located. There are also lots of lorries driving around the main roads as there are salad and building supply warehouses on the back road to Harlow. Saying that, it is nice there and you are a small walk from the Lea Valley park and the River Lea, which is nice.

If CR2 goes ahead Victoria will have been a building site for the better part of 20 years (after the current LU works and other office developments complete in 2-3 years time). Agree with Phil on this one. Besides, New Southgate is likely to be 'a mess' anyway if the 'Boris Tunnels' go ahead, as the North Circular would be taken into tunnel around that point, which would lead to further construction work. New Southgate would benefit from much needed regeneration. As for Balham, this is not an 'option' as that's not what Crossrail 2 are consulting on. If you look at the regional map, you'll see that the key indicates that the Tooting alignment is labelled 'Route Previously Consulted on' (which indeed was safeguarded); the Balham alignment is the proposed alternative. The consultation will not be asking you to vote for which 'option' is better, but you have every right to argue the case for Tooting over Balham in the questionnaire. As you point out, Tooting Broadway's construction methodology is complex/expensive.

Presumably another plus point for Balham from Crossrails point of view is that there will be less disruption to the northern line. Presumably there may have to be some kind of closure at Tooting/Balham stations for a short while to allow for tunnels to connect - shut Tooting and that area is screwed. Shut Balham and people still have the option of Southern.
Saying that if it were to go via Balham, CR2 would basically be duplicating the Southern service between Victoria > Clap Junction and Balham which doesn't seem worth it.
I noticed the Dalston area station is called Dalston and its between Dalston Junction and Dalston Kingsland and no doubt will connect with both. Do you think they might just turn all three stations into one with eight platforms?

Do you think they might just turn all three stations into one with eight platforms? Yes it would be duplicating the Southern service - but the same charge can be made between Wimbledon and Clapham Junction (SWT), Victoria and Euston / Kings Cross (Victoria), Euston - Severn Sisters / Tottenham Hale (Victoria) Stopping at Balham could potentially relieve the Northern line just as well as Tooting, but would also allow passengers from Southern services to change onto CR2 earlier than the overcrowded Victoria and Clapham Junction stops. It would also mean passengers connecting between suburban Southern and SWT services could do so at Balham rather than adding to volumes at Clapham Junction. As regards Dalston - I doubt it would be renamed as a single station, particularly as Dalston Junction and Dalston Kingsland serve different destinations (though they will both serve CR2). Besides we still have the officially separate Bank and Monument stations despite all the connecting corridors below ground, plus Moorgate and Liverpool Street stations (plus the Farringdon and Barblican pairing) will remain separate stations for non CR1 services even though the CR1 station serves them both.

Couple of points that have cropped up elsewhere that might be useful to inject here:
The scale of the work at Wimbledon is apparently due to NR denying the paths TfL wanted, so they have to turn back a significant amount of capacity at the end of their infrastructure - i.e. Wimbledon. This means they need 4 platforms rather than 2, and as such the demolition increases massively. Wimbledon will probably end up with 4 through platforms under the bridge given the terminal roads will need to be as long as the through ones.
The portal is intended to be north of Wimbledon, with a probable cut 'n cover station box, and a diveunder south of the station to get the up line to the other side of the formation (and to get under the Sutton lines). Why on earth not have separate portals so the up CR2 rises up and takes over platform 5, the up slow shifts across as do the other lines, giving you: Up CR2 UP SLOW PLATFORM Up Slow Up Fast FAST PLATFORM Down Fast Down Slow DOWN SLOW PLATFORM Down CR2 Up Thameslink THAMESLINK PLATFORM Down Thameslink
...though the apparent need for CR2 turnbacks does suggest why this isn't an option. Probably easier to just build 4 tunnels under the current lines and link them with lifts and escalators...
Balham's ludicrous diversion. Given the point above, why not serve it on a spur and have CR2 run its tunnels via (and replacing) Earlsfield, and even potentially take some of the BML slow services by having a portal on a Balham spur?

Given the point above, why not serve it on a spur and have CR2 run its tunnels via (and replacing) Earlsfield, and even potentially take some of the BML slow services by having a portal on a Balham spur? One obvious reason is your suggestion makes providing reversing facilities more difficult - having both CR2 platforms side by side allows the provision of a central reversing siding either end of the station (as at West Croydon) plus the easy provision of the necessary crossovers close to the platforms thus minimising the time (and thus the delays to other services) a reversing train blocks the platforms (or their approaches). Another reason is the potential problems it would cause if either the SWML required a closure for maintenance tasks* - the layout at Abbey Wood was deliberately reconfigured to have CR1 and the Noth Kent line run side by side rather than one inside the other for this very reason allowing maintenance and renewal activities on each line to be undertaken separately, particularly given the different power supply modes (OHLE and Conductor rail impose very different limitations on work sites). As for Balham that has only come about because ground conditions along the 'safeguarded' leg via Tooting make construction difficult. Yes I agree, in an ideal world following the SWML and replacing Earlsfield station makes more sense from a 'National Rail' point of view BUT the CR2 project, as with CR1 is very much a TfL one. Hence the focus on keeping these lines as short as possible (the opposite of Thameslink) and the desire to use the Crossrail lines to relieve tube lines wherever possible. This is why we have got he dog leg via Tooting / Balham rather than any significant desire to serve either of these two places specificity at the outset. Finally creating a Balham spur would require a fundamental rethink of a project that is already well on the way to being finalised. Do you terminate at Balham or continue further south to connect to the BML? If so where do you send services to terminate given that unlike the SWML there are no convenient sub end branch lines to take over. Once you start sending CR2 services to the Selhurst / Norwood Junct / Croydon triangle you then hit the problem of all those junctions that need rebuilding - and as with CR1 and Reading**, CR2 then ends up having to contribute to sorting out a mess that is not of its making. There is also a big question over whether linking the BML service patters (which is dominated by having to ensure Thameslink services hit their slots in the core on time) with yet another tightly times cross London service is wise as the repercussions of a delay could extend to half of London if you do. *Note CR2 will be powered by 25KV overheads as far as Wimbledon. ** Note before the GWML electrification was planned, taking CR1 to Reading would have meant CR1 would have had to stump up the cash to replace ALL the signalling from Naidenhead - Reading as the 1960s era kit was not AC traction immune. Hence CR1 were adamant they would not go further than Maidenhead and it wasn't until the GWML electrification had resignalled the Reading area with AC compliment signalling that they changed their mind.

I'd imagine the classic up-PLATFORM-turnback-turback-PLATFORM-down would be used, so all you would need are the crossovers - no sidings. Another reason is the potential problems it would cause if either the SWML required a closure for maintenance tasks* - the layout at Abbey Wood was deliberately reconfigured to have CR1 and the Noth Kent line run side by side rather than one inside the other for this very reason allowing maintenance and renewal activities on each line to be undertaken separately, particularly given the different power supply modes (OHLE and Conductor rail impose very different limitations on work sites). Quite. Part of me hopes they will segregate the branches CR2 absorbs and convert them to OHLE. I'm not holding my breath though! I was extremely disappointed about Abbey Wood, actually. Operational convenience ahead of passenger experience it seems. May as well leave the trains in the depot all day so they're never late and minimises wear and tear then. :/ Finally creating a Balham spur would require a fundamental rethink of a project that is already well on the way to being finalised. Do you terminate at Balham or continue further south to connect to the BML?

The argument being that if serving Balham/Tooting is solely to relieve the Northern Line, then a turnback spur would achieve this well, and reduce the need for demolition at Wimbledon, and would provide empty trains for passengers to get on, which I suspect would be quite the incentive for getting people to switch.

...though the apparent need for CR2 turnbacks does suggest why this isn't an option. Probably easier to just build 4 tunnels under the current lines and link them with lifts and escalators... Why do the fasts have to be in the middle? Given that no fast services stop before Surbiton, we could remove the flyover (which will be nearly 100 years old by 2030) and have the fasts run on the north side of the formation all the way to Surbiton, The slow lines can then follow their original route on the south side of the formation (the Kingston line still has two parallel underpasses under the main line) all the way to the cutting east of Surbiton statin, where there is headroom for a flyover to switch to paired by direction. Or - radical thought - instead of going to the expense of a cut and cover station under the existing platforms at Wimbledon, why not divert the fast lines underneath? No more tunnelling involved, and a much easier station to operate. I would suggest cross platform interchange between terminating services and slow Waterloo ones. People won't need to transfer between terminating and through CR2 services people transferring between through CR2 services and ex-Waterloo services can change at Raynes Park. So: up waterloo/CR2 (divergence east of station) PLATFORM terminating CR2 (one or two tracks) PLATFORM down waterloo w/b CR2 (convergence west of station) PLATFORM up Thameslink down Thameslink PLATFORM .........

if serving Balham/Tooting is solely to relieve the Northern Line, . I still think this will be counterproductive, given the large number of people commuting from SW London to the City - the Northern Line may have more stops between Balham and Bank, but it is far more direct than the detour via Tottenham Court Road Angel. (it follows the A24/A3, which, being the Roman Stane Street, is a straight line)

Snoggle, According to this map from Crossrail it will not carry on to Northumberland Park. So a change at Tottenham Hale, like now, will still be required. Perhaps someone will bring the coffee to the Crossrail planners and they could have a 'light bulb' moment Here is the link crossrail2.co.uk/the-route/

Still i am not paid 40k a year to examine my navel fluff and not see the bleeding obvious. Before insulting the planners perhaps you should examine the map, from which it seems pretty obvious to me that Northumberland Park is the second stop on CR2 after it emerges from the tunnel (the first stop is Tottenham Hale). The consultation document says "New Crossrail 2 services are proposed to serve Tottenham Hale, Northumberland Park, Angel Road ..........Enfiled Lock, [and on to at least Broxbourne] with between 10 and 12 trains per hour in each direction operating directly to, and across, central London" The "core" tunnel will run from Wimbledon to Northmberland Park, but trains will run through it from Shepperton, Hampton Court etc, to Broxbourne - just as CR1 is a tunnel from Royal Oak to Stratford, but carrying trains from Reading to Shenfield, as you clearly understand from the following comment . After all it happened with CR1 when they realised it would be a great idea to move the West terminal from Maidenhead to Reading, logical and better for interchange. It is well known that the reason for the original plan for Maidenhead was that CR1 would have been loaded with the entire cost of resignalling Reading if it had been planned to go there before the GWML electrification was authorised. See also the wrangling over who should pay for the Goblin wiring (either LOROL or GBRf would have had a positive BCR on their own, and both knew it so was waiting for the other to blink), and the original GN electrification to Royston rather than Cambridge

At a meeting with NR/TFL rep present, it was confirmed all CR2 trains would be metro style, i.e. stopping at all stations on the LV line. Presumably this was thought the best way of separating out the fast trains (StEx, Cambridge, etc) on the new fast lines

Snoggle, According to this map from Crossrail it will not carry on to Northumberland Park. So a change at Tottenham Hale, like now, will still be required. Perhaps someone will bring the coffee to the Crossrail planners and they could have a 'light bulb' moment Here is the link crossrail2.co.uk/the-route/Please go back and look at the map. It is perfectly clear to me that all trains on CR2 will stop at T hale *AND* stations north thereof to Broxbourne. Just because the map shows something as a branch does not mean there is enforced interchange to some other service. Please also read the appropriate documents that explain the service levels to be provided on the different parts of the CR2 route. If you don't believe me then I strongly recommend you go along to a consultation session or contact CR2 directly and seek clarification from them.

One obvious reason is your suggestion makes providing reversing facilities more difficult - having both CR2 platforms side by side allows the provision of a central reversing siding either end of the station (as at West Croydon) plus the easy provision of the necessary crossovers close to the platforms thus minimising the time (and thus the delays to other services) a reversing train blocks the platforms (or their approaches). ...but turnback sidings are irrelevant if indeed they do want 4 platforms. I'd imagine the classic up-PLATFORM-turnback-turback-PLATFORM-down would be used, so all you would need are the crossovers - no sidings. BUT that IS NOT what you outlined in your idea for Wimbledon - there are no easy / quick turnback options with CR2 either side of the SWML

Finally creating a Balham spur would require a fundamental rethink of a project that is already well on the way to being finalised. Do you terminate at Balham or continue further south to connect to the BML? If so where do you send services to terminate given that unlike the SWML there are no convenient sub end branch lines to take over. Once you start sending CR2 services to the Selhurst / Norwood Junct / Croydon triangle you then hit the problem of all those junctions that need rebuilding - and as with CR1 and Reading**, CR2 then ends up having to contribute to sorting out a mess that is not of its making. There is also a big question over whether linking the BML service patters (which is dominated by having to ensure Thameslink services hit their slots in the core on time) with yet another tightly times cross London service is wise as the repercussions of a delay could extend to half of London if you do. The argument being that if serving Balham/Tooting is solely to relieve the Northern Line, then a turnback spur would achieve this well, and reduce the need for demolition at Wimbledon, and would provide empty trains for passengers to get on, which I suspect would be quite the incentive for getting people to switch. True a Balham / Tooting spur would indeed achieve the goal of providing relief to the Northern line - but it would also reduce the number of trains at Wimbledon. Given part of the rationale is to remove as many SWT services from the existing surface route as possible (within the constraints of them terminating close to London and the branch infrastructure - i.e. level crossings). In the NE things are a bit different, unlike the SWML the NR takeover is focused on only a single service so the New Southgate branch makes good use out of the majority of trains that would otherwise turn short. At Wimbledon the need to turnback will be limited to engineering work on the SWML, Emergency situations, train failures (including DC / AC changeovers) and a small number of services (no more than 8toh in the peaks IIRC) which the SWML cannot accommodate.

The paired by direction arrangement at Wimbledon made sense when cross-platform interchange was available there, but the current arrangement has all trains on the fast lines batting through the middle of the station at a mile a minute. This is such a safety hazard that SWT have recently erected large fences along the edges of platforms 6 and 7 (with gates provided for access in emergency or on the rare occasions (Sundays, and Wimbledon fortnight) when trains do call at those platforms)
Given that CR2 will surface north east of Wimbledon anyway, it would surely be easier and cheaper to divert the fast lines under Wimbledon and allow all surface trains to use the existing tracks, as follows. Platforms 1-4: District Line Platform 5: up slow - divergence for Waterloo/CR2 at the London end of the platform PLATFORM Platform 6: CR2 terminating Platform 7: down CR2 PLATFORM Platform 8: down slow (convergence at the country end of the station) Platform 9: Thameslink PLATFORM Platform 10: Tramlink
Or, at the cost of some risk of signal delays outside the station, move the convergence to the London end of the station, so that Thameslink can have both platforms 8 and 9. (Or kick Tramlink out to where streetcars belong)
Counsel of perfection would be to make platform 6 a bay so that there was level access to Platform 7, but CR2 passengers for destinations beyond Wimbledon could always take a through train and change at Raynes Park instead of Wimbledon if necessary
