The Granite is a locomotive by Smacker. It is loosely based on the Russian 2ES10 electric 'Granite' locomotive or a generic modern russian locomotive. It has a 'trainee seat' passenger seat in addition to the driver's stand. The attachment positions put the player models through the roof a bit but the view foward is good; there is no real view backwards though. It is recoverable (drops itself).
In real life, the granite locomotives are part of a permanently coupled pair, with one facing each way.
