They make scales to read the weights.
The scales spit the data out RS232.

In my data the cars are approximately 25-30 tons empty and 110-130 tons
heavy.  Rail cars full of rocks in my case.

Automatic equipment identification (AEI) is an electronic recognition system
in use with the North American railroad industry. Consisting of passive tags
mounted on each side of rolling stock and active trackside readers, AEI uses
RF technology to identify railroad equipment while en route.

Wonder if a seismometer would give you a clue as to the cargo content
of the train?  Might have to factor in speed, too.  Does more ground
vibration correspond to more cargo?  How would one determine
gross versus net weights?
