About the Santa Fe NW2:

The EMD NW2 is a 1,000 horsepower yard switcher, its distinctive twin-stack profile and short radiator creating a distinctive silhouette. Perhaps ironic, considering its 1000 horsepower engine, the N in NW2 stood for nine hundred horsepower, with the W designating that it was a welded frame locomotive, instead of a cast frame. The Santa Fe acquired its first two NW2s in 1939, delivered at first with factory issue short exhaust stacks which they then replaced with the longer, conical stacks more commonly seen on later switchers.
