The explosions you see in strafing footage usually is the locomotive engine exploding, not ammunition cargo. Notice in the footage that the pilot is targeting the locomotive itself, not the freight cars.

WWII trains were pulled by steam engines... Their weakness was that any shell penetrating the steam jacket on the main body of the loco will vent super heated water vapor to the outside air in huge 10-20 meter long water and steam jets. Hit with enough holes the result is a complete compromise of the steam jacket, resulting in comprehensive steam explosion.

Yes, it would be neat to see this effect in game... like the same feedback one gets in watching pieces fly off an aircraft prior to it exploding. But I guess it might be difficult and time consuming to do.

Thats not what I am talking about, although its a great effect in its self. I have seen the differance. Nooo this effect im talking about is definately the train car (About middle train) going kablooey!
I even read an article recently about P-51's spotting a camoflaged train and attacking it. On about the 4th pass the explosion was so large it took out the mustang attacking it and the flight leader said it had lifted his plane up sever hundred feet even know he was alrady at several thousand feet up. They speculated that the train was carrying V-1 rocket fuel. And he said it blew debris past his aircraft.
