No, that’s not an ‘additional’ mid platform signal, it’s just a normal signal that’s stood back from a level crossing.

oh i was just going on the OP first post.

Sheffield is an odd one as it is common practice to dispatch trains heading west from 1B on 1 yellow into 1A - not a popular move for traincrew and platform staff but the signallers here have explained previously why it is useful for them to be able to do it with Sheffield's unusual layout.

Do trains then need re-dispatching or is the guard/dispatcher keeping a lookout enough?

Chester Plat 3 is split in half by a signal with a crossover in the middle to the up/down through road.

And that used to be a double-scissors crossing, like that at Cambridge..

If they were slam door they would need redispatching but as they are power door stock no, it just ties up the guard and if provided (TPE and "East side" Northern services self dispatch) platform staff standing to attention until they do pull out.

The main problem it causes is verbal abuse from late runners who come running up banging on the doors and don't understand why they can't get on.

Am I right in thinking Pitlochry in the up direction since the resignalling and loop/platform extension? Up trains stop some distance before the station buildings if a down train is occupying the single line from Dunkeld?

The signals at Pitlochry are set at about one third/ two thirds intervals on both up and down platforms. I believe this was done to allow faster running into and out of the platforms. The Azuma and Sleeper trains have to stop well past these signals in either direction.

All Thameslink core stations have signals along the platforms, but I’m not sure if they’re capable of showing reds? IIRC they are not there for splitting the platform into separate sections for different trains.

They can display a Red and are there basically as "closing up" signals ...

Er.. hadn’t you already replied the same in #21?
