Power for today's train was engine 5000. This was the Santa Fe's first 2-10-4 built by Baldwin in 1930. This locomotive had 69 inch drive wheels while all the rest of the 2-10-4s had 74 inch drive wheels. Most of the engines in this class were assigned to the Pecos Division between Belen and Amarillo.

The engineer poses for a picture while waiting for an air test. The 5000 class 2-10-4s actually developed more horsepower than a four unit set of FTs. But this horsepower was at 40mph. The back emf that builds up as electric motors turn faster actually works against the diesel electric locomotive. However, there were major benefits with the diesels. First, they didn't consume vast amounts of water. This was critical in the desert southwest. Second the drawbar pull of the FTs was almost twice that of a 2-10-4 at low speeds. And third was the addition of dynamic brakes. Both of these factors were essential in the mountainous regions of the Santa Fe Railway.
