DLR incident

[yorkie]

Apparently [on Sunday] morning there was a derailment on the DLR which has been reported on BBC as a breakdown but no mention of it on nationalrail.com http://news.bbc.co.uk/1/hi/england/london/6581363.stm


The BBC mentions many spectators were inconvenienced, but according to my girlfriend who was helping out at the race many runners were on the train
and some were slightly injured, then ran an extra 4 miles to get to the
start on time!

Although I don't have definitive facts, apparently there were problems on
the tube in the morning as well.

Anyone know how a train can hit the platform without derailing?

 

[Coxster]

Atttached to the rails, the train flies up a bit over to the left, hits the platform, scrapes the side (doors) before landing nicely back in the trackbed. Alternatively somone moved the track and/or platform to one side.

Both "a little bit" unlikely I know but hey - when did I ever make sense

I did recieve some texts (Internal staff ones) but have sinced deleted them. From memoryit sounds like a platform edging stone was out of alignment and the train struck it (unable to confirm if it was derailed or just stopped).

I do know that the following train also encountered the same problem.

Bizarre. Why did they not say so, instead of suggesting it was the train that was to blame and then describing something that sounds like a derailment? How very odd.

How is it the train to blame if a platform nosing stone was out of place?

That's exactly the point yorkie is making, if I am not mistaken.

 

[Tom]

I read his post differently...as if he was blaming the train... trust me to read a post quickly... :roll:

This happens more than you think on the DLR, its just cos it was the marathen it got the publisity cos so mainy more people were affected. These trains do rock about loads.

When a 159 is diverted via Chertsey it has to slow down going through stations such as Feltham.

Wonder if the DLR train 'failure' meant it was going to fast and tilted over that bit further clipping the platform.

Also may have had some form of suspension failure which caused it to tilt over and clip the platform.

If you look at Weymouth P2 towards the stop blocks - you'll see a slight curved section removed .......... modified by a loco when it was running round its train over the points there.

(We used to run through to Weymouth with the Cross Countries on Saturdays and Sundays - generally though we'd propel out to the sidings run round and propel back in ........ proper railway. Used to propel into Eastleigh Carriage sidings from the Up Fast too).

Do you know why? Also, any videos showing how much they rock around? Is it a design feature or a defect? Does it apply to all stock or just old/new stock?

That should be impossible on the DLR.

The clearances between the trains and platforms on the DLR are very tight, so it is feasable that the high speed kinematic envelope (the space taken up by the train as they move around on the suspension) of the trains fouls the platforms. If it was going to fast though it would be quite serious, afterall, doing that on one of the tight curves (particularly on the elevated sections) or when another train is infront could be rarther nasty.
As for propelling empty stock, they still do this in France. Whilst waiting in the Eurostar departure hall at Gard de Nord last year I was suprised to see a loco hauled set being propelled into the station. Don't know how far it had come, since I can't remember any sidings near the station, but Le Landy depot and carriage sidings are quite a distance out, so I'd be suprised if it had propelled from there.

 

[Kris]

Yeah they do it properly abroad. I remember watching coaches being propelled into Luzern - bombed in a lot faster than we did it with the shunter standing in the back (open) corridor connection on a radio.

Also watched a freight shunted in Thun - came out of the yard with the shunter on the back wagon - points went over (not pulled by shunter) and train shot back in about 30mph!

Don't mess about over there. Don't know what their casualty rate is.

It woulld have been Le Landy for that stock move, all Corail TER/TIR services out of Gare Du Nord are serviced and based at Le Landy.

However, for pure shunting pleasure take a trip over to Gare D'Austerlitz, especially of a night time when all the couchette and Sleeper trains are being readied. Loads of shunt manouvers and propelling of stock into the station. Gare D'Austerlitz is nearly all Loco and Stock movements no Emu's or TGV's in sight. The best place to be if you ask me! Occasionally as an Employee of SNCF i get to go over to France and we get these 'Educationals' to see what goes on behind the scenes. I have a week in Paris sometime this year when i get to do all this, i am also (hopefully) a cab ride on the TGV est in one of the TGV POS units, so looking forward to that, when it happens i will have the camera ready and will post pictures on my Fotopic.

think it is just the suspencion, Bank tunnel is the worst for this happening but all the public know is that they had to wait a little longer than normal for their train to arrive as the train goes into the very back of the head-shunt, if you are going to Lewisham there about every 3 mins so no problem, if you are heading for King George V then I would advise you get the circle/district round to Tower hill and change for the DLR there:tongue3: . I videos that would show the rocking are http://www.youtube.com/watch?v=UQG1qLUoltM , http://www.youtube.com/watch?v=FTxW3aJMjlU and http://www.youtube.com/watch?v=2dojmiIm7io

I do know that the following train also encountered the same problem.

Sorry if this is a stupid question, but why was the following train allowed to encounter the problem? Surely the issue should be resolved before any more trains are allowed through?

Thanks gavelex. Is it getting worse over time? Seems like it. Also is it worse when accelerating/braking?

Not rearly, more going round bends and points and when traveling at high speed (well, as high as you can get on the DLR).
