The problem is so many different systems, not like driving a car where learn the highway code and off you go. I know the blue levers local lock the points, not just the black leaver, but at the points as well. And trains carry a token for the section. There does not need to be a blue level for rails not carrying passengers. And we also have a system for flags and signals.
I think the only lights are on level crossings, some the fireman has to walk into road with red flag, one has a time delay, so the barriers can't come down until there has been a time for traffic to clear, it does cause a problem when that station is end of run, as to put engine at front of train, it has to go over the crossing, ground frames operated, then return, but crossing counts axles so once engine clear, barriers open, then driver has to wait, and then press button to return.
The bell is not longer required, as the road section never reopened, engines only have whistles and horns, no bells any more. But I have never trained as a fireman, it is not the best job in hot weather, and need to pass out as fireman before one can start training as a driver. I have a feeling may need to train as guard before fireman but not sure.
We have three signal boxes, but think one only has the radio repeater housed in it, and the station uses ground frames, the guard has the radio, not any loco crew, so not sure how guard tells loco crew? I have not seen an emergency cord, and never looked on how the guard applies brakes, I think he only has a wheel to brake the carriages while he disconnects and connects hoses.
Seems brakes work with a double vacuum one pushes brakes on, and other off, with a single vacuum line between carriages, second line is for the steam heaters.
The carriages have no way for transfer carriage to carriage so guard can only apply on carriages brakes. However speed limit is 15 MPH flat out.
