General Electric Oil-Electric Boxcab

In 1928, General Electric introduced a series of diesel-electric boxcab locomotives with engines from Ingersoll-Rand. All major equipment apart from the diesel engines was built by GE themselves, unlike the earlier ALCO-GE-IR boxcabs where ALCO was responsible for the construction of the whole chassis and running gear. All had two two-axle trucks, but the weight and power varied between different variants.

The lightest were two sixty-ton models with a 300 hp six-cylinder engine. The greatest number of eleven was built of a 100-ton variant that had two of the 300 hp engines. The Illinois Central was the biggest customer of this variant with six locomotives. GE built a single 120-ton prototype for the Erie that had a single 800 hp engine. Another 120-ton locomotive was built by the Canadian National in their own shops and had two 300 hp engines like the 100-ton model. The only one existing today is also a 100-ton model, built for the contractor Foley Brothers and now on display at California State Railroad Museum in Sacramento, California.
