HO F7A / F7B Locomotive Set ATSF #257L and #257A (ATHG19574)
HO-scale Santa Fe F7A/F7B Locomotive Set featuring ATSF #257L and #257A. This two-unit pairing captures the dual-service heritage of Santa Fe’s F-units, with the B-unit equipped with a steam generator and both locomotives finished with water fills for prototype accuracy. Painted in the cat-whisker scheme, the pair reflects units commonly assigned to both freight duties and occasional passenger power on the roster.
Design and performance details include a heavy die-cast frame for traction, a Genesis driveline with a 5-pole skew-wound motor for smooth, quiet operation, and a suite of authentic features such as see-through cab interiors, LED lighting, etched metal details, and body-mounted knuckle couplers that are Kadee-compatible. The models are DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector; some configurations offer onboard DCC sound with Tsunami2 decoders and dual speakers, working in DC or DCC. The set uses RP25 wheel contours for reliable track contact and all-wheel electrical pickup, with a minimum operating radius of 18 inches (22 inches recommended) to ensure smooth performance on typical HO layouts.
