Approach controlled trainstops.

Hi All!

I know that generally approach controlled trainstops were more widely installed after the Moorgate disaster, but before that were they used much at terminal stations and were any other forms of control used to ensure a train was doing a safe speed at a terminus?

No, trains had a green signal right up the to the Fixed Red Light in front of the stops or sand drag although dead end tunnel sidings were being equipped with additional yellow warning lamps.

Am I right in thinking that all terminal platforms now have a repeater for the red lights at the end of the platform?

if i remember rightly the yellow aspects are only in the tunnel sidings e.g liverpool street

the programme was called TETS Trains Entering Terminal Stations and correct is was due to the accident at moorgate

the circuits work on a time delay from when a particular track circuit drops thus giving a feed to the valve controlling the trainstop

but some places use a old fashion way of doing things in a way of a piece of pipe which has to be filled before there is enough pressure to push down the trainstop head.

No, there were one or two places with them (Ongar, Chesham has A1000 which is yellow/red, Bank used to have similar with WK7) but as a rule you get a green at the last signal.
