The easiest way to do this is to model a "stub switch" -- but to look 'right' that depends on
a) the era you are modelling
b) the era the "prototype" of that location was constructed.
c) the type of railroad there -- backwoods, no-tie-plate shortline vs Class 1, etc
If it works mentally, a nice harp style switch stand would also be in order .......
With best regards, SZ
