I thought the stone throwers were on the District Line? The kids living on that estate behind Westbourne Park used to chuck stones at the trains and into the station, when I lived there - I don't know if they still do...

Coalville eh? Shame, I'm only down the road in Loughborough, would have been good to see them. Well, someone's gotta live here I wouldn't mind betting there's some vantage points along the Old Dalby line, where the train could be viewed getting put through it's paces? This is the only place I could find on Trainspots.

Wouldn't you also need to find the area that has been electrified to LU 4th rail standards too?

I thought the stone throwers were on the District Line? They exist on most lines (except maybe on the Victoria or Waterloo & City - though of course I could be wrong.) Those who do the throwing are not normally educated enough to distinguish one line from another. It's simply a moving target.

I went up to Old Dalby today for a safety briefing from Serco and for familiarisation. Train 2 is looking good and was undergoing coupling tests with the Serco loco. Driving Motor car 21099 is fitted out internally with BT test equipment but other than that the train is fully fitted out (it is however missing some minor items such as low level PEA's at the RVAR area).

Apologies for going off topic but adding to the discussion on flat bottom rail / concrete sleeper vs bull head rail / timber sleeper track. The current BTR track work is to install continuous welded rail. The main benefit is the improved ride quality through the elimination of rail joints. The absence of wheel impact at joints reduces maintenance being better for the rails and fixings and for the trains wheels and axles. It also reduces noise and vibration. However, maintaining long strings of welded rail in open sections is different to maintaining the traditional jointed short rail. Being essentially a long piece of metal the expansion and contraction of rail due to temperature variations cannot be ignored. To reduce risk of track buckling long CWR sites are installed with a special procedure to prestress the rails by varying amounts according to temperature prior to fixing down to sleepers. In effect they act as giant stretched springs in cold temperatures and relax as the temperature increases. This prestress is carefully set and fixed in the rails and needs to be reset if disturbed by maintenance work such as tamping and removal of ballast or sleepers. Before the PPP, selected areas had CWR installed by contractors such as Grant Rail and all new CWR on the SSR is installed by Balfour Beatty Rail. By the time I left P-Way in 2003 there wasn’t the in-house expertise to maintain CWR as it was fairly new to LU. However, there did exist obselete Long Welded Rail on network which the expansion switches at the ends of LWR sites were checked regularly. districtdave.proboards39.com/index.cgi?board=general&action=display&thread=431Higher train speeds also need a more uniform track formation and deeper drainage to prevent excessive lateral and vertical movement of the track. The scope of BTR work does not include track drainage as agreed in the PPP contract. I understand it was taken out due to costs. Some of the early CWR areas suffered from wet-beds where the sub-grade below the ballast is highly saturated with water. This is attributed to the breakdown of the clay forming voids that collect water that is not being collected by defective drainage. As a train passes over a wet bed, capillary action sucks water up through the ballast. Furthermore, the water will mix with ballast dust or ‘fines’ to clog up the voids in between ballast stones. It will form a hard mass thereby removing from the ballast formation the ability to absorb track loads. The original construction of track formation is thought to be poor and there is little accurate historical records. Early on, the infracos were only obligated to inspect and assess existing drainage assets in the first 7.5 year contract period. Drainage replacement work is now done ahead of the BTR as a separate package of work. Drainage and everything below ballast level is a civils asset.

Hi, not to sure if this has been posted anywhere on here, but this site has photos of the s-stock at Old Dalby. The new -ve rail can be seen as well.

It's [almost] confirmed that ten trains will be stabled in Lillie Bridge depot, quite how they will get in and out efficiently without signalling modifications, is not understood by management!

There are to be several mods to signalling, layout etc. once the depot is properly signed over to LU. I believe they are looking at Lillie Bridge being one of the main depots.

That will make life easier for the District Line (it finally gets its depot back!) and go some way to replacing roads lost in the triangle sidings.

Lillie Bridge will be mainly for overnight stabling and could be used as a 'bolt hole' during the day. We will share the facility with TLL, although the site will be back in the LU portfolio.

Just to update you all, I went up to Old Dalby again today and went out on train 2 on the test track. The train is running well, with all the expected usual little niggles and hiccups, and achieved 60km/h. There were quite a few enthusiasts on an overbridge so it may well be worth having a general trawl of the internet from now on!

Does that mean that both access points to LB will be used, i.e. via West Ken and off the Olympia branch? Would it not be in theory advantageous to reinstate the connection into NR from the Oympia branch?

Would it not be in theory advantageous to reinstate the connection into NR from the Oympia branch? As the subject of Lillie Bridge has now been brought into this Forum i can report a conversation, going back to Aug/Sept last year, with a senior Piccadilly Line manager saying that timetabling meetings with SSR had revealed that provision was required to be made "in future" Picc Line timetables for: 4x trains stabling from Olympia. 4x trains stabling direct from Hammersmith EB, (detraining at Hammersmith rather than West Ken) 2x trains stabling from West Ken WB, then shunting via crossover. 2x trains from Barons Court WB, via Hammersmith siding, Hammersmith EB fast- detrain!, West Ken.

Bookmark: www.imeche.org/playback now I watched the lecture last night - they said that a C Stock is having the sensitive edge fitted. When will this C stock enter service? The lecture was quite interesting - the two speakers were quite uninspiring and dull though!

Engineers are appointed for their engineering skills. Being inspiring speakers isn't one of the core skills. If they were inspiring speakers they might have gone into politics or the law instead.
However, if you want to learn about S stock it was an excellent lecture. I was there.

I quite agree - At the Presentation at the S-stock mock up it was interesting to hear the difficulties with the cup holders! However, it was good to hear the detailed engineering side from the lecture video - and also to hear about it from the engineers themselves.

Two doorways of 'C' Stock will be fitted with sensitive edge strips for about six months. The system is passive and as such Train Operators will have no interaction with it whatsoever, in addition the unit we are using will be kept in the middle of the formation. It will allow us to gather data and set up the final system in a more operationally focused way. lecture was quite interesting - the two speakers were quite uninspiring and dull though! The Senior Project Engineer is a good guy and really knows his stuff, he works well with us. At the end of the day though they are engineers and not operators.

I think I gave you a little more than that, and just to be clear my knowledge of the train is equally as detailed but more focused on the operational requirements. In essence I don't really care what happens behind the console when I press the button (although I do have a healthy interest!), my job is about where that button goes and how my staff will interact with it.

The presentation slides are also on the IMechE site. helix.imeche.org/http/2009/s-stock.pdfEngineers are appointed for their engineering skills. Being inspiring speakers isn't one of the core skills. If they were inspiring speakers they might have gone into politics or the law instead. It's an age old complaint engineers being poor communicators. The institutions are always talking about trying to improve their public image. I'm sure IK Brunel was no wet lettuce.

Interestingly, the degree I'm doing at Loughborough has taken this into consideration. We had an entire module in it last semester called...'Communication'. It was commented in a lecture that engineers are notorious for not being the most inspiring people to listen to. Doubly ironic, since noone laughed at the irony of an engineer saying that!

I was told it was fitted to doors on the unit 5513 - 6513, though this was an outer unit when I saw it the other week. Perhaps this is some other bit of test kit mind you, or perhaps it isn't operational yet. This is just gossip mind you, I'd always defer to PRJB's greater definitive knowledge.

The trial has not yet started but will start in the next few weeks, also 5513-6513 is not the unit we are utilising. The unit used had some additional wiring for some previous work which we utilised, 6513 was the unit that had air con fitted so I can see why people would think that this was the unti we were using. I don't want to announce which unit we are using for fear of jeopardising the trial results, but Aspect (or LU staff) if you pm me I will fill you in.
