Description

The EMD SD70ACU is a 6-axle 4,300 hp (3,200 kW) road switcher diesel-electric locomotive originally built by General Motors Electro-Motive Division as an SD90MAC, and rebuilt by the Norfolk Southern Railway and Progress Rail Services. They are operated by two railroads, Norfolk Southern and the Canadian Pacific Railway.

Rebuilt units have added rear ditch lights per NS prototype
Rebuilt units have 5-chime horn per prototype
High headlight location per NS practice
All selected road numbers have deck mounted ditchlight placement

The SD70ACU began under Norfolk Southern, who rebuilt their SD90MACs to this configuration at its shops in Altoona, Pennsylvania. The first locomotive entered the rebuilding process in September 2015, which was number 7299. As of 2019, all 110 units have been released into active service.

All of the SD70ACUs will be rebuilt with the latest EMD cab which meets current FRA crashworthiness standards. The Siemens electronics will be replaced with Mitsubishi electronics. The rebuild also includes the installation of Ultra Cab II, locomotive speed limiter (LSL), and cab signals. The trucks will be rebuilt only as needed and they are not getting traction motors swapped out.

In 2018, Canadian Pacific started a similar rebuild program with their long dormant SD90MAC fleet. Unlike NS, the work on these rebuilds will not be done in-house, but by Progress Rail at their Mayfield, Kentucky and Muncie, Indiana facilities.
