A short freight consisting of grain hoppers departs the Texas Gonzales and Northern yard in Harwood, Texas, and makes its way to Gonzalez to switch some elevators there. Power for this train is TXGN "SW10" 105. A 1952 product of EMD, this engine was originally Western Pacific 605. It was later acquired by Union Pacific, and rebuilt into one of their SW10 switchers with the distinctive raised radiator section. On the UP it carried number 1273. It was eventually sold to TXGN, which numbered it 97 before changing it to 105.
