Yes it is. Engineers trains still touch the second half, however it’s pretty much unheard of for a 95 stock to go there. Even if a push out were happening, I’m not sure they would go to the bother nowadays of putting the train in there.
Happened in the late 1990's There was a conductor rail defect which left a good few 95 stock trains marooned in various sidings without shoes, they were retrieved over the following week by night crews and available managers.
I know this is off topic but I hope you will find it interesting.
I was the driver of the defective train though I had very little to do.
A possession was taken for these moves.
The train at the front was dragged out with no issues but when the following train came to be rescued it was realised that the train had not been shut down and the batteries were completely dead, it was left there for plans to be made to rescue the following night.
The following night it was coupled to an assisting train, we then discovered the the "Back to back " radios did not work through the length of a train while it is in a tunnel and as the defective train had no battery power the usual comms could not be used.
The trains coupled up and the parking brakes removed*, a member of staff positioned in every car ready to reapply in emergency
All points were secured for the route out of the siding and The trip cocks were cut out on both trains which allowed the trains to run through red signals. This also restricts trains to 10mph.
The train was dragged out of Kennington into the NB platform, and a little way up the bank branch to allow 12 cars to clear the points. I have no idea why not the SB platform.
We then set up for the trip south, fortunately the route from Kennington to Morden is uphill so there was little risk of a breakaway, though 95 stock couplers did not have a good reputation.
1 member of staff in every car to apply brakes if needed and also to relay messages to the rear train if needed, three in the cab, me, a train tech and a senior signaller.
My instructions were to ignore any red signals and to shout if I felt anything was going wrong.
The assisting train the pushed us to Morden depot, wrong road to Stockwell then over the points, which were signalled for me but which had also been secured just in case they did something strange after the first train has crossed them. There is always a possibility that legacy signalling may do something strange when not being used as designed.
Then on to Morden, no problems anywhere on route, the only signal I had to pass at danger was the shunt signal into the depot at Morden, this could not be cleared until the train is fully berthed in the platform and a 12 car would not fit.
We did have concerns about the train climbing the hill to the depot but no problems.
All in all a fun night.
Is there a driver in the front one able to apply brakes to both of them?
No the only electrical between trains is a communication cable.
