There are a number of interesting animated freight cars in Trainz.
The JSA steel coil wagon is on the Download Station, kuid 92263:16102
The cover opens to load and unload:

The cover closes for transit.
The red out-of-gauge car is also animated.
Normally the load bearing arms are closed, but when loading the arms first move outwards:

The steel plate loads:

The bearers rotate:

And for transit the steel plate is now within gauge:

Again, on the Download Station, kuid 114867:1050
Both of these cars are used in a session of mine for YardSwitchingCo. Look for "YSC 1a SteelAnime", kuid 69871:12057, or this thumbnail:
