I am even thinking; what if the freight car is locked on the locomotive and it is replaced by another.......
It's most likely that i am making this harder than it should be.
thanx for the insight of keeping it simple.
The freight car is locked on the track not on a Locomotive.
Since you can put the freight car only in a path where the locomotive (or the sums of the locomotives) is 3 or greather it does not suffer the locomotive change.
You only "upgrade" locomotives, so you change a locomotive with one with a greater value then the conditions for having the freight car are never lost.
