Blowing railroad bridges

[Liebchen]

Just a quick question.  If you are playing the JTS Panzer campaigns, such as France 40 Gold, and your opponent blows a rail line bridge that you want to use,

if your engineers put up a bridge over that hex, will it still serve as a valid rail line that you can transport RR loaded troops over it?

Thanks!

Nope. Engineers cannot build rail bridges, only "heavy" bridges.
