Walthers Mainline, HO Scale, 910-21003, EMD SD75M, BNSF #8252, DCC & Sound – Model Train Junction: Quality Parts and Art Supplies

Bring big power to your HO railroad with the WalthersMainline SD75M! Built from 1995 to 1996 at the request of the Santa Fe for a higher horsepower unit (4300 versus 4000 for a standard SD70), most were later transferred to the new Burlington Northern & Santa Fe Railway following the 1995 merger, where many are still in service for BNSF.
