can brides with railroads be destroyed?
Every time I attacked such a bridge i never destroyed it.

And if it can be destroyed, what happen to the train?

Yes, you can destroy railroad bridges. The train will just fall down and explode!

no the train will just stop at the edge until the bridge is repaired.

ahh, but i think he means if the train is on the bridge while it is destroyed

The train will most likely explode, usually only infantry "falls" into the water when the bridge is destroyed.

yes train bridges can be destroyed. however when repaired in a temperate map the train bridge dont repair back with the railroad sections on them so yeah. but as far as i know they do repair normally on snow maps. (cause WW knew they needed that feature only on a snow map for their one TS mission where you have to get the Sonic Crystals back. so i dont think they bothered to fix the bug for temperate maps.)

if the train is on the bridge when destroyed then yes it will explode/fall. however if the bridge is destroyed before hand i think the train just stops
