context_page_description: The Dash 9 Series is a line of diesel locomotives built by GE Transportation Systems. It replaced the Dash 8 Series in the mid-1990s, and was superseded by the Evolution Series in the mid-2000s. Dash 9 series locomotives are some of the most common in the United States.
context_section_description: All 1,090 units of this model were built for the Norfolk Southern Railway, as road numbers 8889 to 9978.
  The orders for these units were basically an extension of NS's previous order for the standard cab Dash 9-40C (or C40-9) (see above).
  They were built under the same premise that a lower power rating than the 4,400 hp (3,300 kW) rating of the Dash 9-44CW (or C44-9W) (see below) would prolong the life of the engine, and use less fuel.
  However, there is a manual override switch that allows the engineer to run the engine with all 4,400 hp (3,300 kW) if necessary.
  As with the C40-9, Norfolk Southern began to upgrade their C40-9W's from 4,000 to 4,400 hp and AC traction in mid-2015, making them AC44C6M's as well. Others will be rebuilt as the AC44C6CF.
  Power output: 4,000 hp (2,980 kW)
