Notes:

These models' frames started developing problems in later years (made out of zamac with lead, which deteriorates over time). The trucks on these models are made out of cast white metal that doesn't age well, either. The company sent out a survey with the release of this engine, asking if S modelers would be interested in the RS-2 and RSD-4/5.

The original version came as a sort of kit, where the chassis and body were assembled, but you had to install the handrails, the cut levers, brake details, and windows. Over the years, AM changed to selling the complete model, ready-to-run.
