"The SD70M-2 is the SD70ACe's DC-traction counter-part. Like the SD70ACe, the locomotive was rated at 4,300 hp. NS ordered all of their SD70M-2's at 4,000 hp. Norfolk Southern (NS), Florida East Coast (FEC), and Canadian National (CN) were the only customers to purchase this locomotive new.
"CN has the most SD70M-2's of any railroad, at 190 units."
