Approximately what time period would it be prototypical to run both the early version and the late version of the Athearn Tank Train cars in one train?
I'm no expert but from Spookshow's description I'd guess 1982 (when the 282 series was built) to 1997 (20 years after the 486 series was built). http://www.spookshow.net/freight/athearntanktrain.html
