The EMD SD70 is a series of diesel-electric locomotives produced by the US company Electro-Motive Diesel in response to the GE Dash 9-44CW. Production commenced in late 1992 and since then over 5,700 units have been produced.

The SD70M has a wide nose and a large comfort cab (officially known as the "North American Safety Cab"), allowing crew members to ride more comfortably inside of the locomotive than the older standard cab designs. There are two versions of this cab on SD70Ms: the Phase 1 cab, which was first introduced on the SD60M, and the Phase 2 cab, which is a boxier design similar to the original three-piece windscreen on the SD60M, which is shared with the Phase 2 SD90MAC, SD89MAC, and SD80ACe. The Phase 2 cab has a two-piece windscreen like the Phase 1 windscreen but the design of the nose is more boxy, with a taller square midsection for more headroom.

The SD70M is equipped with D90TR DC traction motors and the 710G3B prime mover. They are capable of generating 109,000 lbf (480 kN) of continuous tractive effort. From mid-2000, the SD70M was produced with SD45-style flared radiators allowing for the larger radiator cores needed for split-cooling. Split-cooling is a feature that separates the coolant circuit for the prime mover and the circuit for the air pumps and turbocharger. There are two versions of this radiator: the older version has two large radiator panels on each side, and the newer version has four square panels on each side. This modification was made in response to the enactment of the United States Environmental Protection Agency's (EPA) Tier 1 environmental regulations. Also the truck was replaced with HTCR-4, instead of HTCR-I on former model.

Production of the SD70M ceased in late 2004 as production of the SD70M-2 model began (the EPA's Tier 2 regulations went into effect on 1 January 2005). 1,609 examples of the SD70M model were produced. Purchasers included CSX, New York, Susquehanna & Western (NYSW; part of EMDX order no. 946531), Norfolk Southern and Southern Pacific (SP; now part of the Union Pacific Railroad), but the vast majority were purchased by Union Pacific.

In 2000, an order of SD70Ms made history when Union Pacific ordered 1000 units of the model (UP 4000 through UP 4999, inclusive, although 4014 was renumbered 4479 to accommodate steam locomotive Big Boy 4014 in 2019). This order was later extended by nearly 500 additional units (UP 3999 and below, UP 5000 and above, except for 3985, which was left vacant for the Union Pacific Challenger 3985).

This locomotive model is also built for export, and is still catalogued by EMD (at 4,300 hp or 3,200 kW). CVG Ferrominera Orinoco has 6 SD70Ms that were built as an add-on order to UPs FIRE cab equipped SD70Ms. Companhia Vale do Rio Doce (CVRD) in Brazil has ordered 55 of this model for service in Carajas pulling trainloads of iron ore. Since CVRD track is gauged at 1,600 mm (5 ft 3 in), a wider bogie, the HTSC2, was designed for these units by EMD. Wikipedia.
