Introduction

Athearn 28678 HO Scale ALCo RS-3 Rio Grande D&RGW 5203

ALCO built the RS-3 to respond to competition with EMD, Fairbanks-Morse, and Baldwin Locomotive Works. In the case of ALCO, the builder added more improvements to create new locomotive lines beyond the RS-2. ALCO produced 377 RS-2s versus the more successful RS-3s at 1,418.

The new model produced slightly more horsepower than the earlier design at 1,600 hp using Alcos 12-cylinder, model 244 prime mover. Visually, the RS3 very similar to the RS2. Both had much more styling then ALCOs first diesel, the RS1. Additional curves with strong beveling to corners and edges giving the unit a much more streamlined appearance. At the time, some railroads elected to employ theirs RS3 diesels in passenger/commuter service. Many railroads appreciated this model for its versatility and reliability. RS3s were one of Alcos shops more popular locomotives.

DRGW purchased five RS-3s in 1951 and used them for local and switching service. Along with the S2s and PAs, they were the only ALCOs on the roster. Only unit 5204 was ever repainted into the black switcher scheme; the other units wore their original paint until retirement. By 1966 the units were off of the roster.
