The SD70MAC is one of the most common locomotives plying the rails today, from east to west, Alaska to Mexico, in freight and passenger service. Originally introduced in 1993, the production of SD70MACs now totals more than 900 units. The BNSF unit represents a one-of-a-kind paint scheme used when Burlington, Northern and Santa Fe announced they would be merging. These models feature lighted ditch lights and numberboards along with a directional LED headlight, Kato knuckle couplers and a factory-installed DCC socket.
