HO SDP40F Locomotive Amtrak Phase II #537 (ATHG64119)

HO Amtrak SDP40F Locomotive, Phase II No. 537 is an HO-scale replica of Amtrak’s SDP40F diesel locomotive, captured in the Phase II paint scheme. This model is designed for standard HO layouts, delivering a faithful, period-accurate representation of 1970s Amtrak power with detailed lighting and cab features. It uses a DCC-ready design with Quick Plug 21-pin NEM connectors for easy digital control, and select versions offer onboard sound for added realism.

Road-number specific features for No. 537 include an early pointed nose, icicle breakers, dual steam generators, and ACI plates, while the broader SDP40F lineup adds illuminated ground and classification lights, lit number boards, and front and rear MU hoses. The model includes a detailed cab interior with a control stand, a large fuel/water tank, and finely rendered details such as flush-mounted window glass and see-through intake grills. Built on a heavy die-cast frame with eight-wheel drive and RP25-wheel contours, it runs smoothly on HO track with a minimum radius of 18 inches and a recommended 22 inches. Some versions are offered with onboard DCC sound (SoundTraxx Tsunami2) for authentic engine, horn, and bell sounds when used with a DCC system.
