AAR control stand on an EMD DDA40X; Other EMD models are similar. A control stand is a diesel-electric locomotive subsystem which integrates engine functional controls and brake functional controls, [1] whereby all functional controls are "at hand" (within reach of the locomotive engineer from their customary seating position, facing forward at all times). [2]
The following is a list of locomotives produced by the Electro-Motive Corporation (EMC), and its successors General Motors Electro-Motive Division (GM-EMD) and Electro-Motive Diesel (EMD). Streamlined power cars and early experimental locomotives
All Mark 4 Control Cars have full-sized driving cabs with EMD locomotive type power and brake controls. Locomotive control is by means of an AAR system, modified by Iarnród Éireann (IÉ) to include control of train doors and operate with 201 Class locomotives. Iarnród Éireann formerly operated Mark 3 Control Cars from 1989 until 2009:
In 1972, EMD introduced modular control systems with the Dash-2 line; the EMD SD40-2 became one of the most successful diesel locomotive designs in history, both in terms of sales and service longevity. A total of 3,945 SD40-2 units were built.
These locomotives are easily identified due to their full-length fuel tank, disappearance of the battery box cabinet, and a rectangular windshield on the engineer's side of the cab. Internally, the locomotive's standard control stand was now replaced with a short desktop control stand. Production spanned from August 1990 to September 1991.
With a new computer software for the on-board computer and one inverter per axle (or "P6"; EMD named it "Individual Axle Control") - unlike most of previous EMD locomotives that use one inverter per truck, the SD70ACe-T4 is capable of generating 200,000 pounds-force (890 kN) of starting tractive effort, and 175,000 pounds-force (780 kN) of ...
Locomotives could be built with the engineer’s control stand installed for either the long hood, or the short hood designated as the front. Two control stands for either direction running was also an option, but one end would still be designated as the front for maintenance purposes.
