HO AC4400CW Locomotive UP #6837 (ATHG31693)

This HO-scale AC4400CW locomotive models Union Pacific UP 6837 in authentic early-production livery. It captures distinctive UP styling with a red frame stripe, a Leslie 3-chime horn, a large roof GPS dome, and a walkway capacitor box, delivering a convincing prototype look for operation and display on an HO layout.

Inside, a Genesis driveline with a 5-pole motor and a heavy die-cast frame provides solid traction and smooth, quiet running. The model is designed for both DC and DCC use, featuring DCC-ready Quick Plug technology with a 21-pin NEM connector, LED lighting with illuminated number boards and front/rear walkways, a full cab interior, see-through cab windows, etched walkway steps, and fine-scale Celcon handrails. McHenry scale knuckle couplers keep Kadee compatibility, and RP25 wheels ensure compatibility with most HO track. Sound-equipped versions add an onboard DCC decoder with Tsunami2 sound and dual speakers for realistic engine, horn, and bell sounds, plus full DCC functionality and adjustable features via CV changes, making UP 6837 a compelling centerpiece on any layout.
