HO RTR RS-3 Green Bay & Western 307 (ATH28684)

HO-scale Green Bay & Western RS-3 No. 307 is a detailed, ready-to-run representation of ALCO’s RS-3 diesel locomotive, faithfully painted in GB&W red with bold initials on the hood. Designed for HO layouts, it recreates the railroad’s Wisconsin operation and its RS-3 roster, delivering a faithful centerpiece for GB&W-themed layouts. The model comes fully assembled and ready to operate, with finely applied decoration and window detail that adds realism to any scene.

Notable details include metal grab irons, fine-scale handrails, and see-through etched radiator fan and cab windows, as well as McHenry scale knuckle couplers compatible with Kadee. The drive system uses all-wheel drive with precise gearing for smooth, quiet operation and reliable electrical pickup, with RP25 wheel contours for compatibility with popular HO track. A new, more powerful and quieter can motor drives a 5-pole skew-wound design with flywheels and a multi-link drivetrain, and DCC-ready versions include a 21-pin plug for easy digital installation. Sound-equipped models feature onboard Tsunami2 decoding with a cube speaker and LED lighting for long life; engine, horn, and bell sounds work on DC and DCC (some functions limited on DC). The locomotive requires an 18-inch minimum radius and faithfully reproduces GB&W’s historic red scheme, including the Nathan P-3 horn, partially-blanked cab windows, a steam-era bell, and a warning beacon with a flashing light on DCC+sound versions.
