context_page_description: The EMD SD70 is a series of road switcher diesel-electric locomotives produced by 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; most of these are the SD70M and SD70MAC models. All locomotives of this series are hood units with C-C trucks, except the SD70ACe-P4 which has a B1-1B wheel configuration, and the SD70ACe-BB, which has a B-B-B-B wheel arrangement.
  Superseding the HT-C truck, a new bolsterless radial HTCR truck was fitted to all EMD SD70s built 1992-2002; in 2003 the non-radial HTSC truck was made standard on the SD70ACe and SD70M-2 models; the radial HTCR truck remained available as an option.
context_section_description: The SD70ACS is a 4,500 horsepower (3,400 kW) AC variant for heavy haul freight, used in desert environments. The first 25 units were ordered for Saudi Railway Company in April 2009 and assembled in the London, Ontario plant for delivery in the second half of 2010. Special features include a pulse filtration system, movable sand plows, EM2000 control system and FIRE display system.
  Mauritania's Société Nationale Industrielle et Minière placed a contract for six SD70ACS locomotives in October 2010.
  In July 2011 Etihad Rail ordered seven SD70ACS locomotives for delivery in 2012. Seven locomotives were delivered in 2013.
