Signs .......

[Deleted]

Ive just had a look on Colin's site

I have a few (possibly irritating) questions to ask regarding the signs.....

What is the difference between A and B catergory platforms?

Also, what about the R(X) and T(X) signs?

Direct links to the R(X), T(X) pics....

One of the catagories means the driver can't see all the way down the platform, so if the CCTV cameras are broken they must get a station assistant to despatch all trains, or the platform must be closed until the CCTV can be repaired. The other catagory can still be worked if there is a CCTV failure, but I think they might have open the cab door and look out - I'm not sure, someone else can probarbly elucidate further. Which type is which evades me at present.

Category A platforms are platforms that are either curved, regularly crowded, lacking in platform-side OPO equipment, full of furniture that obscures the view of the platform, or on the off-side of the train. At these stations, if the OPO equipment fails then the driver is effectively 'sat down' until station staff can give him/her the RA.

Category B platforms have none of the above caveats, and at these stations the driver can simply stick his head out of the window.

R (X) No train radio between here and the next station.
T (X) No tunnel telephone between here and the next station.

I've had a reshuffle, which has made the above links useless. The pics in question are below, for reference:
