BNSF ES44C4 6615 is the final unit on this intermodal at Beevers, NM on March 1, 2011.

A closer look at BNSF ES44C4 6615 at Beevers, NM on March 1, 2011. The 6615 is one of the first batch of 25 units which has 4 powered axles instead of 6. At speeds below 15 mph the center axle can be raised to increase the weight on the four powered axles. Compare the trucks on the 6615 with the lead truck of the preceding unit (5519). The cylinders and lever controlling the mid axle height provide a much "busier" appearance on the 6615's trucks.
