Freshly-remanufactured Union Pacific AC4400CWM units 6930, 6913, 6904, 6911, 6933 and 6910 were outbound on the Wabtec-BNSF interchange just north of the builder’s Fort Worth plant. The locomotives had been built in 1998 as 7500-series AC6000CW units and were renumbered when they were repowered with 4400-horsepower prime movers. |
