Hi Shawn,
Just another bit of trivia on the 2-10-2's used by the B&M and later MEC... They were called “mud suckers” by the crews because the power feed from the tender was prone to feeding all the dirt from the bottom of the tender into the firebox. It's the one B&M loco of interest that I haven't found plans for. They had boosters in the tender that had a driving rod on the tender trucks - I don't know if that rod can be modeled in ORTS.
Regards,
Scott
