A new run of the Athearn HO scale Electro-Motive Division (EMD) GP7 is arriving in hobby shops. The Genesis-series diesel locomotive features railroad- and road-number-specific details. Join Model Railroader senior editor Cody Grivno as he hosts this video review of the four-axle road switcher.

Paint schemes offered in this run of the GP7 include Pennsylvania RR (Dark Green Locomotive Enamel); Bangor & Aroostook (dark blue in two road numbers, American Revolution Bicentennial scheme in one number); Great Northern (simplified scheme); Kansas, Oklahoma & Gulf (black, red, and white in one number); Midland Valley (black, red, and white in one number); and St. Louis-San Francisco (Frisco, Mandarin Orange and white). Each road name is offered in three numbers unless noted.

The Athearn HO scale EMD GP7 features an injection-molded plastic body; a die-cast metal chassis; and a Genesis driveline with a five-pole skew-wound motor, machined flywheels, and multi-link drivetrain. The road switcher, which has a minimum radius of 18”, has all-wheel drive and electrical pickup.

Additional features include light-emitting-diode lighting; Celcon handrails; separate, factory-installed windshield wipers, m.u. and trainline hoses, lift rings, uncoupling levers, and wire grab irons; and etched-metal radiator intake and fan grills. The model has a plastic fuel tank with fillers, gauges, breather pipes, and retention tanks. The Blomberg-B trucks have railroad-specific bearing caps. The cab window glazing is clear, and the side windows are positionable. The cab interior is painted and detailed.

Direct-current models with a 21-pin NEM connector are priced at $219.99. Versions with a dual-mode SoundTraxx Tsunami 2 sound decoder sell for $319.99.
