HO GP40-2 Locomotive with DCC and Sound, DRGW #3121 (ATHG-1752)

HO GP40-2 Locomotive with DCC and Sound in DRGW 3121 is an HO-scale model of EMD’s GP40-2 freight locomotive, built to deliver authentic operation and sound on a typical layout. It combines a DCC decoder with SoundTraxx Tsunami2 sound, dual speakers, and full DCC functionality while remaining operable on DC layouts. Ready for easy installation with Quick Plug plug-and-play technology via a 21-pin NEM connector, the model features prototype-inspired details such as see-through cab windows and lit number boards in Rio Grande livery, delivering a convincing centerpiece for a modern freight scene. A Genesis driveline, five-pole motor, and a heavy die-cast frame provide smooth, quiet pulling power and solid traction, complemented by LED lighting and RP25 wheels for reliable on-track performance.

Road-number specific DRGW features for 3121 include a black gyralight bezel, Rio Grande nose logo, and a cab vent on the right side, with additional accuracy drawn from prototype drawings and photographs. The model emphasizes scale detail—fine Celcon handrails, etched metal fan grilles, see-through cab interior, and a detailed fuel tank—creating a faithful, ready-to-run representation. Designed for broad layout versatility, it offers all-wheel electrical pickup, LED lighting, and compatibility with common couplers, and supports full-range DCC control with a minimum turning radius of 18 inches for operation on a wide variety of hobby layouts.
