HO GP40-2 Locomotive Primed For Grime UP Ex-SP #1413 (ATHG-1743)

HO-scale GP40-2 locomotive finished in Primed for Grime, representing a UP-ex-SP unit numbered 1413. This weathering-ready model captures the look of an in-service diesel and provides a ready starting point for hobbyists to add grime, rust, and wear to taste. The primed finish offers a realistic, canvas-like surface that’s ideal for custom weathering, delivering a convincing, workhorse appearance straight from the box.

Designed for authenticity and dependable performance, this GP40-2 features prototype-inspired detailing and a robust drivetrain, including a see-through cab with a full interior, fine-scale handrails, etched fan grilles, and a detailed fuel system. It rides on Blomberg trucks with scale knuckle couplers and RP25 wheels for smooth operation on common layouts, with LED lighting for realism. The model is DCC-ready with Quick Plug 21-pin NMRA connectors, and some versions offer onboard Tsunami2 sound with dual speakers for full DCC operation. Road-number-specific detailing reflects UP/SP heritage for the 1413 prototype, and the design accommodates an 18-inch minimum radius, making it a versatile weathering-ready option for HO model railroaders.
