SD45s 904 and 910 at Springfield, Missouri (date unknown).

The units are on Track 2, at the southeast corner of the service track area. In the distance, on the far side of the service shed, one can see the silver sand storage tower, elevator leg, covered unloading shed and air tank. On Track 2 the locomotive wash rack is to the east (right) of the photo. Out of frame to the west (left edge of photo) is the Kansas Avenue overpass.

Special thanks to Mark Davidson.
