HO PA-1 and PB-1 Locomotive Set with DCC and Sound UP 607 607B (RPI23566)

HO PA-1 and PB-1 Locomotive Set with DCC and Sound in UP 607/607B livery. This HO-scale two-engine pairing reproduces the classic Alco PA and PB locomotives for Union Pacific-themed layouts, offered as individual A units or as an A-B set for prototypical operation.

These models reflect the second-run ALCO PA/PB details, including 3D-scanned nose and roof profiles and a wealth of road-name specific detailing, full underbody piping and conduit, separate grab irons and handrails, etched-metal grilles, lit number boards, and a full cab interior. They ride on Rapido’s proven drive system for smooth, reliable operation and are offered with DC Silent (21-pin DCC Ready) or DC/DCC/Sound options, featuring ESU LokSound V5 decoders for authentic engine sounds. Available as individual A units or as A‑B sets, these HO-scale PA/PB locomotives deliver a highly authentic UP appearance and performance to the layout.
