Why don't you send an e-mail to Broadway Limited Imports and ask them. No one else is going to know about a product that hasn't even been released yet. It's probably nothing more than a second production run.
Looking on their website it seems that it's just a second release with different road numbers.

I got four the first run,they derailed,the second run Broadway said they were redone so i got two more,and guess what,no good also.The shaft comeing down to power the trucks is offset,i think that is the problem.
