@0-Gauge CJ posted:The Challenger I have been eyeing is a 30-1107-0. The MTH website doesn't say if it's PS-1 or PS-2.
Actually, it's PS-nothing. This is the basic conventional model that only includes a somewhat lame whistle board. You won't have any running sounds, crew talk, bell, etc. The -0 tells the tale, that would be a -1 if it had PS/1. It for sure couldn't have PS/2 as it was released years before PS/2 came on the scene.
