A trio of BN SD40-2's curve around the bluffs as they make their way south along the Mississippi River on the Aurora Sub. The train is working in the section from La Crosse to Savanna. Lynxville is located 46 miles south of La Crosse.
The 3rd unit is a SD40-2B. The BN had 3 of these interesting units. Most of them were rebuilt from units that were wrecked over the years. The 7501 was rebuilt from BN SD40-2 BN 6914 in October 1983. The unit was originally built in 1972 as BN 6337. The unit is currently the BNSF 301 and normally assigned to hump service in Galesburg.
