Does this mean in normal service there wont be any trains terminating at Newbury Park, North Acton, Loughton or Northolt? Thanks

Think the names are a disappointment. The Lioness line could have been the Wembley line to pay homage to football but still give an idea where the line goes. The Weaver line could have been the Valley line for the Lea valley. As someone who knows London very well and its transport network ill be looking up the names of the lines as they aren't obvious where they go. Obviously the names will stick in time but the names are so no descript. At a time when 6 lines are having a rebrand something that has not happened ever it would have been helpful to give them geographic based names.

Concerning the Bakerloo line, you say 'LUL basically just trying to keep the trains running for as long as possible.', I don't know what else there is to say considering the current financial situation? The Piccadilly Line can't have it's life-expired signalling replaced with ATP/ATO systems due to the funding not being in place. Getting new trains is not easy as it sounds - the 2024 stock introduction comes with alot of prep. Co-acting signals being commissioned, new sidings & depots being upgraded, platforms being altered in order to accommodate for the new stock. Of course they are trying to keep all the fleet running for as long as possible, there isn't the money available! Hence why the CLIP project is here, BBC News pointed out it's a 'refurbishment not replacement'. This rather comes down to the whole life asset management process (which I think is the role of the Annual asset condition assessment and resulting Asset strategy review). This is something the government specifically asked TFL to improve is the conditions of the early bail out agreements. As I understand good Asset Strategy and Management practice requires a regular review of the balance of maintenance/heavy overhauls/refurb (sometimes called interventions) against full replacement. Same sought of thing you may do yourself with a car - when is it time to stop throwing good money after bad with repairs and running costs and instead spend that on loan repayments/depreciation on a newer one.? Asset management is clearly an issue but its a serious concern that the 1992 &1996 stock are all having major issues. The 1992 stock particularly extremely unreliable from introduction with someone can't unfortunately think who saying "The Central Line now works almost as well as it did in the days before they spent £800m on it" when they introduced the 1992 stock. Anyone know anything more about the defects i have heard mentioned about the 1995 stock?

Many lines seem to be struggling to provide the timetabled service because of a lack of good stock especially in peak periods. I wanted to get a list on one thread of what's wrong with each stock and the plan for repair. I have a vague idea of the stock issues each line has, I know there are many more knowledgeable people on here that could hopefully provide more specific details? Bakerloo - New timetable introduced to release trains for accessibility works. They have had life extension works too recently in 2015 that repaired the body work of the trains. LUL basically just trying to keep the trains running for as long as possible. Central - Major long term motor issues that at the moment is causing around 20-25 train cancellations every peak period. The heavily delayed CLIP is trying to remedy the issues. Jubilee - Major car body issues and serious cracks that have resulted in some trains long term stopped and some trains being cannibalised to keep others going. What is actually happening to repair the long term issues of the major body cracks? Northern - Some issues been mentioned but I cannot find much about the 95 stock and the issues they are having. Anyone know how many trains are being cancelled because of a lack of serviceable stock? Piccadilly - Regular cancellations - not sure of the specific reasons. The last few autumn seasons have been hard on the wheels of the 73. Replacement obviously planned soon. Victoria - Any issues with the 09 stock? I am under the impression this is the most reliable stock on LUL SSR - Any issues with train defects causing cancellations? Waterloo & City - The only line that can run all required trains? Some more information from those in the know would be great

yesterday’s figures: AM peak 20 trains cancelled from TTN88/23 (71) PM peak 15 trains cancelled from TTN88/23 (71) So that’s just 51 trains in service! What’s the cause of 20 cancelled in a peak? That’s a shockingly high number! Thanks Dstock7080 for those numbers 😊

Train cancellations seeming to get worse lately. Nearly every day now severe delays because of a shortage of trains. I know 5 are in use for the CLIP. How big is the maintenance pool and does anyone know how many are missing from service every peak? 😊

Is this what happened before the T5 extension? When Heathrow Terminals 2&3 opened both platforms were used as terminating platforms like at most terminating stations. Then in 1986 T4 loop opened so all trains operated via T4 and only via the eastbound platform 2 at T2&3. Then in 2008 when T5 opened the platforms at T2&3 became used for T5 services with T4 services only using the eastbound platform. From the T4 loop trains can access both the westbound and eastbound platforms at T2&3 before using a crossover east of the station to get onto the eastbound line. I imagine this arrangement this weekend allows the usual 8-10 minute crew break at T4 to move to T2&3 to keep the service moving.

There I was thinking this would be just a Jubilee Line issue due to train defects. Wonder if we will soon see this on the Circle and H&C lines that seem to suffer from "train cancellations" I wonder what the underlying cause for the Central line? Driver shortage, train shortage due to the long running Central Line Improvement Project or just constant major train defects? Thanks

With the best will in the world, there are only so many Met controller’s available and they are susceptible to an NHS track & trace or app notification to self isolate as much as anyone else. That may or may not be the case on this occasion but that is the most likely explanation for last minute unavailability. Your right! Control room staff were pinged by the NHS app www.bbc.co.uk/news/uk-england-london-57874404

Part of total track replacement at Queen's Park, including North Shed. What you haven't seen, but has been happening is the 3 weeks or so of prep work done for this every night, which has caused 1 of the Queen's Park stablers to be at Stonebridge Park, and the rest of Queen's Park stabling to be reshuffled to keep North Shed empty. Are they relaying the track in the south shed as well as the crossovers? Or just the platforms and north shed? Thanks

87½ trains of 1973 Stock were built for the Piccadilly. 83½ still remain after losses and reforms. how come they can only offer 78 for service (79 when rat back ) ? is it due to overhaul and unserviceable trains ? Each line (with the exception of the Waterloo and City that uses 5/5 trains in the peaks) holds some of its trains back in the peak periods. This is so trains can be overhauled, be examined, and be refurbished. It would be too much on the depots to have every train leave twice a day. Also its better to have X% spare even if you can physically run them. The Jubilee could maybe hit 32tph with all 63 trains in service. it only actually runs 59 for 30tph so that if say 3 out of 63 were faulty or needed heavy maintenance the full normal service can still be provided with 59 good trains. Rather than to cancel trains at the last minute due to the depot not being able to release them.

Don't know where you got the figure of 86 trains on the pic line I'm sure there is only 79 trains . 78 in service at moment while they put the rat train back together 87½ trains of 1973 Stock were built for the Piccadilly. 83½ still remain after losses and reforms. No wonder this puts pressure on the depots during leaf fall season with only 5½ trains! I got the figure from an official London Underground Rolling Stock Unit formations file. it stated the Piccadilly had 86 trains comprising 172 three car units. Dated 31st March 2014, a little out of date i know. It was from What Do They Know as a result of someone's FOI request. If anyone wants a copy i can always send it over as it contains every unit number for every train at that time. Thanks for the info guys

The working timetables do not give information about how many trains can be stabled at each depot, sidings, etc . Some of the fleet will be under maintenance and not shown in timetables. I'm just curious as to where trains are and can be stabled, particularly in relation to planned upgrades such as the new Piccadilly fleet. The operation of depots and where trains can stable is something that isn't really discussed on this forum. Especially compared to other topics. People here are so knowledgeable!

Hi guys, I was wondering where all the trains are stabled when out of service at night. I also wondered what the capacity of each depot and fan of sidings was. From the working timetables for each line I can tell where the trains start and finish but this doesn’t cover the entire fleet. From what I’ve stated below is from my own research & guess work. There are almost certainly a few mistakes. I’m sure many of you know better and I’d be very grateful if you could put me right. Thanks in advance! Will Bakerloo
London Road Depot (Capacity 11 trains) Stabled 11 trains Queens Park North and South sheds (Capacity?) Stabled 7 trains Stonebridge Park Depot (Capacity?) Stabled 12 trains Elephant and Castle (Capacity?) 1 train in either platform 3 or 4 Are Elephant and Castle 23 & 24 roads used to stable trains too? That’s 31 out of 36 trains. Where are the remaining 5 located? Central
Ruislip Depot (Capacity?) Stabled 17 trains White City Sidings (Capacity 16 trains) Stabled 12 trains Woodford Platform 1 – Stabled 1 train Woodford Sidings (Capacity 5 trains) Stabled 5 trains Hainault Depot (Capacity?) Stabled 32 trains Loughton Sidings (Capacity 10 trains) Stabled 10 trains That’s 77 out of 85. Where are the other remaining 8 located? 4 presumably within White City Depot. Jubilee
Stanmore Sidings (Capacity 10 trains) Stabled 10 trains Neasden Depot (Capacity?) Stabled 20 96ts Stratford Market Depot (Capacity 33 trains) Stabled 28 trains That’s 58 out of 63. The other 5 trains presumably located within Stratford Market Depot Northern
Edgeware Sidings (Capacity 13 trains) Stabled 13 trains High Barnet Sidings (Capacity 12?) Stabled 8 trains Highgate Depot (Capacity?) Stabled 16 trains Golders Green Depot (Capacity?) Stabled 17 trains Morden Depot (Capacity?) Stabled 42 trains That’s 96 trains out of 106. Where are the other 10 located? Piccadilly
Uxbridge Platform Stabled 1 train South Harrow Sidings (Capacity 7?) Stabled 4 trains Northfields Depot (Capacity?) Stabled 34 trains Arnos Grove Sidings (Capacity 7 trains) Stabled 6 trains Cockfosters Depot (Capacity?) Stabled 34 trains That’s 79 of 86 trains. Where are the others located? Victoria
Northumberland Park Depot (Capacity?) Stabled 36 trains Victoria Siding (Capacity 2 trains) Stabled 1 train Brixton (Capacity 2 sidings, 2 platforms) Stabled 3 trains (2 in sidings, 1 in platform) Walthamstow (Capacity 2 sidings 2 platforms) Stabled 2 trains in platforms. That’s 41 of 47 trains. The other 6 presumably stabled in Northumberland Park Depot. Waterloo and CityWaterloo Depot (Capacity 5 trains?) Stabled 4 trains 1 train stabled at either Bank or Waterloo 5 of 5 trains accounted for.

The argument seems to go that the Jubilee line is an important line, but its trains are becoming unreliable lately, so it is time to replace them. But never mind because we can use them on the Northern line, the most used of all lines! As if unreliability doesn't matter over there! Focusing on the proposed 96ts transfer to the Northern that would mean a total fleet size of 169 trains (106 95ts + 63 96ts). Would the Northern require all these trains in peak service or would this create a larger pool of spare trains that aren't required in peak service? Would this provide an opportunity to weed out and remove a number of particularly unreliable units on both the 95 and 96 stocks increasing reliability? The 7th added car would be removed and would the 96ts be based at one depot and the 95 at the others. I assume due to the high degree of similarity that both fleets would interwork but return to a specific depot out of service? Thanks for any knowledge as always

Why wouldn't you just specify the same doors for replacement stock? Unless there is a problem with where the doors (and thus PEDs) are situated on the 96ts it would seem to me to be a total waste of money to charge it for the sake of it. The Siemens trains for each line are not going to be exactly the same anyway. AIUI the issue isn't so much placement as door width. The 96ts has single leaf doors at the car ends, this restricts the number of people able to alight/board thus extending station dwell times. The desire is for the new stock to have all double leaf doors (like the S Stock). New trains will in the future move away from traditional design standards. There has always been rolling changes in standards on the tube normally starting with an innovation on one particular stock shifting to the design of others. An example is the innovation of externally hung doors first introduced on the 1992ts. When that became the new design standard is has been a feature of all since introduced featured on the 95/96/09 and S7+8 stocks. The new Piccadilly trains will likely serve as the first of the newest generation of walkthrough double door trains. All trains will more than likely follow this. They will be of a different design according to the NFTL feasibility report "NTfL has identified that it is possible to provide an inter-car gangway by altering the Tube train design to incorporate an articulated configuration with more, shorter carriages. By positioning the vehicle bogies under the ends of two adjoining cars, the relative vertical and lateral movement of the carriage ends is significantly reduced." This is not just about the positioning of doors but a move to a new design of train . The double doors will obviously help handle the crowds if 33-36 TPH that is to be handled by the comparatively older Bakerloo, Central, Piccadilly and W&C lines when compared to the Victoria. The design will also allow trains to travel at higher speeds on all the lines they serve with smaller cars allowing trains to negotiate the tight junctions and bends that exist on the lines they serve. The Jubilee will be no exception.

It is almost certain that the new trains won't have the exact same spacing of doors as the 1996ts so new PEDs will be required for that reason. At the time of new trains the PED's will have come to the end of there life at that time anyway they will likely need replacing for reliability reasons.
Before the new stock is introduced there will have to be a removal of the current PEDs. This is surely the only practical solution. This will lead to a period of no PEDs on platforms while both new and old stock operate until all 96ts trains have departed and all new trains introduced. this will be the point when PED's return to the Line.
The departure of the 1996ts and the introduction of new stock may over a year or more anyway with the average rate of building a train for the tube being one per week. The only practical solution is to operate without PEDs during this time as it will not be possible to use them with two different stocks with different doors at the same time.
The reason for providing PED's was it eliminated the need to provide draft relief shafts and meant the JLE engineers could get away with not chamfering the ends of the running tunnels saving money. As well as the obvious benefit of passenger safety and design of the stations.
The major decision will be in the design of the risk assessment and any legal implications in operating without PED's for a period. The risk assessment will likely say something along the lines of - trains arriving and departing at slower speeds during the changeover to manage drafts and to enable operators to stop short of someone falling, increased staff and police presence in the stations and the fact that the other JLE stations manage without them (as does the rest of the tube) so can the JLE underground stations for a period provided appropriate safety measures are taken.

As a brief aside, are there any alternative rail services that aren't already overcrowded that could relieve the pressure on what would be a reduced service on the Epping branch of the Central line? Apologies if this is off topic. Agreed! Would it not be possible to run 4 car trains in off peak times or during night tube even if it was just a few trains per hour that were 4 car rather than all services. Surely having more trains in the depot whilst maintaining the same TPH being able to receive maintence would be beneficial?

Having recently been travelling around London and hearing an increased noise level as well as the reported (now cancelled) industrial action I wanted to try and better understand the issue of track noise. Obviously most of it comes from the tight bends in the track with elements of the train wheels scraping along the track such as at Bank on the Central line. What I hope to better understand is why is there so much noise on some straight newer sections of track like on the JLE? and what is Pandrol Vanguard track and why is it causing so many issues as I believe its strongly disliked by drivers? Thanks

When it was going to be the Westinghouse DTG-R signalling and then the Bombardier CityFlo system originally the first stretch to be installed was Rayners Lane to Uxbridge but under CBTC they changed there minds why? Who knows The reason they changed their minds was because with all the cancelled contracts they were aware the circle line and district weren’t getting the capacity increase required so they began this time by introducing the system in central London first to give a capacity increase on the circle and district first and the metropolitan last. The northern Met Amersham and Chesham is now the last area planned to be completed rather than the first for this reason.
