One of the first successful AC traction motor-equipped locomotives, railroads nationwide purchased large numbers of the SD70MAC. Although most commonly found on coal trains and railroads with heavy grades where their slow speed performance was essential, the locomotives wandered into all sorts of services and locations. Mergers and sales have increased the variety of paint schemes worn by the thousands of SD70MACs still in service today. Lionel's latest run of this modern muscle includes some of these patched and repainted units along with the one of a kind BNSF merger scheme. Also for the first time, these locomotives are available with Bluetooth control and in two powered numbers and a SuperBass unit to really amp up the sounds as you put them in Run 8 on a heavy coal drag!
