Has anyone a photo of the body damage to the 456? Or is that a beheadable offence?
Has anyone a photo of the body damage to the 456? Or is that a beheadable offence?
At around 05:42 hrs on Tuesday 15 August 2017, a passenger train leaving London Waterloo station travelling at about 11 mph (18 km/h) collided with a stationary train of wagons. There were no injuries, but both trains were damaged and there was serious disruption to train services using the station.
The passenger train was the 05:40 hrs South West Trains service from Waterloo to Guildford and comprised 10 coaches, a combination of class 455 and class 456 electric units. The wagons were standing on a line adjacent to the intended route of the passenger train and had been provided as a safety barrier separating passenger services from an area where construction work was being undertaken as part of the Waterloo station upgrade project.
The collision occurred because a set of points were misaligned and directed the passenger train away from its intended route. The misalignment was a consequence of a temporary modification to the points control system which also caused the train driver and signaller to receive indications that the points were correctly aligned.
Our investigation will examine:
the circumstances leading to installation of the temporary control system modification
the safety measures provided while the temporary modification was in place
the checking and testing procedures applicable to the modification
any relevant underlying management factors.
Yep points locked and detected one way (normal) and were physically facing another (reverse). Now over to the experts to determine why.
I understand it was actually "detected Normal" but lying half-and-half/midstroke. Which would answer the question of "derailment or collision" , train would have derailed on the switches and then been guided towards the barrier train by other components of the double slip.

Effectively a repeat of Clapham all those years ago - overnight works handed back misassembled which catch the first train next morning (Clapham was the first trains to run at a close headway the next morning, this is the first service on this routing the next morning).
So the RAIB will be looking at what post-Clapham measures, whose implementation caused huge costs and works delays over the years since, have now been let go.
The consequences here were fairly limited, imagine the same scenario applied to a higher speed line.
That's a standard item in any RAIB's investigation, nothing specific to this particular Waterloo collision."Our [RAIB's} investigation will examine:

Similar thing happened at Cardiff last year didn't it? That was a very lucky outcome also!
Interesting point about how the stock for the service got into the platform in the first place or had it been stabled overnight?
Of course if the point circuits had been "by passed" it could have gone into the platform "run through" the points and then been signalled out over the now standing off points and no one would have known.
Do you know what you're on about? Do you sign the road into Waterloo?
The answer is from that rubbish you posted, almost probably not. :roll:
What's wrong with it? It seems a reasonable scenario to me. What has signing the road got to do with it?

Only HPSS points don't give when run through to my knowledge. But as it looks like the detection was was frigged, who knows where the points were laying, did they move and detected correctly for the inward movement (if indeed there was one). But with the C end of those points inside the possession with a train sat on them, the A and B ends shouldn't of been able to move let alone facing the wrong direction. All the while the signalling diagram and the signal were showing the correct route out for what was set. This will be a big one when the report comes out.
Are you suggesting that head's will roll because of it and the implications of it?
Also the possibility of legal action as well?
No, but I think some big lessons are going to be learned from this one. this is a RAIB report, so heads don't roll with them, but I expect there might some harsh criticisms for the railway to take onboard.
Precisely. They may have been fitting up Reverse before.But if the train had run through the points then they wouldn't be in the position they were in when it came back out.
Because there may be multiple ways into a platform through different sets of points. Just because a comes out via a set of points doesn't mean that's the way they came in.
Sunset's post qualifies his statement better as he/she states that the points are the only route into the platform.
