A modern EMD road locomotive
Introduced in the mid-2000s, the SD70ACe continued EMD's long line of six-axle freight locomotives while using AC traction and updated emissions technology.
What SD70ACe means
SD identifies EMD's six-axle Special Duty family, 70 places it in the SD70 series, AC identifies AC traction, and the final 'e' is associated with the emissions-era evolution of the design.
How to identify it
The SD70ACe is a large six-axle road locomotive with a wide North American safety cab and substantial rear radiator/cooling section. Details vary among production groups and railroad orders.
Heavy-haul work
Its six powered axles, AC traction and high tractive effort make the SD70ACe well suited to heavy freight, including bulk trains and demanding grades. Units can also be used in distributed-power arrangements.
Identification reminder
Locomotives are rebuilt, repainted and modified during long careers. Use several clues together—road number, trucks, hood and radiator details, cab shape and known roster history—rather than relying on paint alone.
