    Don't know whether this is the right place for this topic. So sorry in advance. ON the 150s, for example 001 and 002 plus the 150/2 variants with sliding cab doors, how are the doors released, closed and also how is the actual cab door opened, closed or locked. The same with the 172s. Also, on the FGW 150s and the new 172s, where are the door controls at the vestible doors in the passenger cabin as I have seen the LM 150s at FGW being fitted with a system so you can open the doors anywhere. Can someone please explain the above!

    Thanks. I understand if this thread is moved!:lol:

    I don't think you'll find any train crew members willing to give out such information. why do you ask?

    I do not fully understand this question. For the doors on the bodyside, the Conductor/Guard puts a key in the Door Key Switch and operates the Local Door switch.

    What is ''the actual cab door?''
    Not sure about 172s, but 168s and 170s have a handle within the cab which is pulled and the door slid open manually.
    What do you want explaining? There are intermediate panels in the passenger saloons by certain doors which allow the doors to be operated from within the saloon.

    I can't shed any light on 172/Turbostar stock as we don't have any, but the door operation on 150s is fairly standard. Controls are situated in the cab-end vestibule either side of the train, requiring a secure key-operated switch to be activated first.

    On swing door 150/0 and 150/1 stock the crew door is opened manually to carry out a platform check, the passenger doors are then 'released' from the door control panel. Doors are then closed from the panel, crew door locked shut and 'ready to start' signal is given on the buzzer. On 150/2 units the crew doors are sliding powered, and are opened/closed using a separate switch. As I say, pretty standard stuff.

    Don't worry! I'm not going to steal the train! I was just wondering as you never really think about it and I've always been interested about how things work or operate.

    I meant the exterior cab door and I did mean the saloon doors. I get it now too!

    Out of curiosity is there a CDL bolt on the 150/0 and 150/1 exterior cab doors?

    Not on the 150/1. They can be locked though, and there is no passenger access to them from inside the saloon as that door is locked each time it closes.

    The 150/0 has a sliding power door for crew access and I would expect this is interlocked to the brake/traction relays as on the 150/2.

    It may not be interlocked as the 455 'local door' is not interlocked and the 455 door controls are very similar to those on the 150.
