HO GEN SDP45 Locomotive BN #6597 (ATHG-2002)

An HO scale EMD SDP45 diesel locomotive in Burlington Northern livery, road number 6597, this Athearn model faithfully recreates the SDP45 prototype with the steam generator compartment at the long hood end. Fully assembled and ready to run, it offers a detailed, prototypical presence for mid‑century passenger and mixed‑traffic rosters, including a full cab interior, LED lighting, and scale Celcon handrails that enhance on‑layout realism.

Designed for HO layouts, the SDP45 uses a Genesis drivetrain with a 5‑pole motor, flywheels, and a multi‑link drive for smooth, quiet operation. It rides on a heavy die‑cast frame with all‑wheel electrical pickup, RP25 wheel contours, and body‑mounted scale knuckle couplers. DCC‑ready with Quick Plug 21‑pin NEM connector, it supports NMRA‑compatible functions when paired with a decoder. Road number 6597 features BN‑specific detailing, including ex‑GN heritage with hi‑low brake cylinders and rear‑end numbers, and the model is ready to run on HO layouts with minimum 18" radii (22" recommended).
