The two locomotives were routed to Progress Rail’s Tacoma facility earlier this summer for repainting prior to delivery. Tacoma Rail No. 7001 was spotted outside Progress Rail yesterday in fresh paint this week. The locomotive was former EMDX No. 1211.
The two SD70ACe-P4s will initially be leased with an option to purchase. Tacoma Rail’s SD70ACe-P4s have the distinction of being the first two SD70ACe-P4s produced new.
The departure of these locomotives leaves only two remaining demonstrators in EMD’s fleet, SD70ACe-P4 EMDX No. 1207 and SD70ACe-P6 EMDX No. 4223.
The SD70ACe-P4 is EMD’s solution 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.
