• Abstract:
  This paper describes locomotive tractive effort testing on Norfolk Southern Railway. The purpose was to measure maximum locomotive performance under real-world conditions on wet and dry rail. A variety of DC and AC locomotives were tested, ranging from low power switchers and gensets to high power road units. Typically, two locomotives were used as head-end power, followed by Research Car NS 32 for data collection purposes, and then a number of loaded hoppers that were individually weighed on certified scales. Testing was conducted near Roanoke, VA; the 2.75 mile test segment ascended a 1.38% average grade with a series of four, six and eight degree curves. Loaded hoppers were either added to or cut off the rear as needed to achieve a 10 mph (approx. 16 kph) average speed up the mountain.
