N SF RR-56 Mechanical Reefer (RPI561003A)

Santa Fe RR-56 Mechanical Reefer is an N-scale model of a mid‑century mechanical temperature‑controlled refrigerator car, designed for realistic freight operation on model railroads in N scale.

Based on original blueprints and photographs, this detailed model recreates period features such as separate door posts, door latches, and coupler cut levers; a fully detailed underframe with piping and equipment; cushion draft gear; two roof hatches for open or closed operation; see‑through side grills; and a Trane diesel generator for authentic appearance. The RR-56 class helped launch Santa Fe’s all‑purpose mechanical temperature control fleet, with the RR‑60 and RR‑61 variants built to the same standards (with insulation variations), making it a convincing centerpiece for mid‑century freight on an N-scale roster.
