Ok I spouse I need stop markers for different number of carriages.
What about the back of the train?

Also I guess we are going to need a tag to say "The last set of doors
will not open" as the platform is not long enough.

Maybe we should have door marks, ie Rather than say the train stops
here say where the doors should be; I've seen these marked on the
platform in some parts of the world and parts of the Tube have
automatic doors fixed to the platform!
