CSX #102 is a
road slug. I cannot find this road number on any CSX locomotive roster so maybe it's just headed to the scrap pile. I do not what type of locomotive this was before rebuilding as a slug. Alco?
Road slugs take advantage of diesel electric locomotive surplus power available at low speeds. Take a mature diesel, remove the diesel, generators, cooling, dynamic braking, cab, and air compressor and you have a frame with traction motors below. Replace the removed mechanicals with ballast like concrete, get power from a "
Mother" locomotive and you have a unit with as much as double the tractive effort at speeds of less than 35 MPH or so. CSX has somewhere around 150
road slugs and 30 or so
yard slugs.
