rail damage and rail movement

[ComradeP]

It might be a nuisance, but it's not very punishing for the attacker. The defender needs to keep damaging rail hexes in order to block rail movement if the attacking side has a rail capacity (otherwise the first damaged rail hex will limit all further movement along that line as units can't change back into rail mode).

Other (war)games feature mechanics where in order for a rail line to be functional, it needs to be able to trace an unbroken path to the map edge, with broken rail lines requiring repairs or a requirement for rail lines to be converted to the gauge used by the side capturing the hex with the rail line in it.
