+1 from me.
Today I have noticed the same issue and found same recommendation like OP. :-]
More advanced options for this issue:
Some long vehicles could have more doors. Like long trams. Every vehicle should have defined “Number of doors”.
Cargo Trains – I have 2 points of view-do it same as passengers- short platform has 2 loadingdevices, longer platform 4 loading devices and longescargo station willl have 8 loading devices
What you think?
