MAYFIELD, Ky. – EMD will shrink its demonstrator fleet of SD70ACes when it ships two locomotives to a Texas utility. Luminant, the largest generator of electricity in Texas, will take delivery of two EMD SD70ACes from EMDs current fleet of 10 demonstrators.

EMDX Nos. 1204 and 1205 arrived at Progress Rail’s Mayfield shop in late September for work prior to their movement to Texas. The two units will receive new road numbers and reporting marks, becoming TUGX Nos. 53008 and 53009. Its currently unknown if they will be repainted or retain EMD colors.

The departure of Nos. 1204 and 1205 will leave EMD with eight demonstrator SD70ACes, all with axle control technology in both P4 and P6 configurations. Axle control uses one AC inverter per axle for a total of six inverters. Traditionally, EMD AC traction locomotives have used one inverter per truck. An SD70ACe with axle control is designated as an SD70ACe-P6 to differentiate them from standard SD70ACes.

SD70ACe-P4s are EMD’s answer to provide an AC traction alternative that is equal to or better than the performance of the company’s SD70M-2 that uses six DC traction motors. The six-axle SD70ACe-P4 uses four AC traction motors and two idler axles nearest to the fuel tank.

EMD demonstrators in the P4 configuration are EMDX Nos. 1207, 1211 and 1212 while the P6 versions are EMDX Nos. 1206, 1208-1210, and 4223.
