HO SW1500 Locomotive ALS #1506 (ATH-2522)

HO-scale EMD SW1500 switcher locomotive ALS #1506 from Athearn is a detailed model designed to reproduce the four-axle diesel switcher used in yards and industrial settings. It captures the SW1500’s distinctive dual exhaust stacks and compact silhouette, making it ideal for authentic switching scenes on an HO layout.

Designed for flexible operation, this SW1500 features an injection-molded, highly detailed body with see-through radiator grilles and cab windows, LED lighting and operating ground lights, and finely rendered handrails. It rides on RP25 wheels with McHenry scale knuckle couplers (Kadee-compatible) and is DCC-ready with Quick Plug 21-pin NEM connectivity; sound-equipped versions add a SoundTraxx Econami decoder with a single speaker for authentic engine, horn, and bell sounds. Available in multiple roadname schemes such as GN, ALS and ITC, it suits a wide range of prototypes, and a minimum 18-inch radius makes it friendly for smaller home layouts.
