Locotrol

Locotrol is a product of GE Transportation Systems (GETS) that permits railway locomotives to be distributed throughout the length of a train (distributed power). It is installed on more than 8,500 locomotives around the world, sending signals from the lead locomotive and via radio to the remote control locomotives.

Locotrol was developed in the 1960s by an Ohio telephone and electronics manufacturer, North Electric Company. The technology was later purchased by GETS predecessor Harris Controls. The electronics were mounted in a separate railcar, but have since been miniaturised into relatively small cabinets with much of the functionality contained in software. Early Locotrol customers included the Southern Railway, Norfolk & Western RR, Canadian Pacific and Australia's Mount Newman Mining and Queensland Rail. Today 20 companies use the system, with 5,000 systems deployed.

Since 1975, both Queensland Rail and Mount Newman Mining (now called BHP Billiton Iron Ore) in Australia have used the system on coal and iron ore trains, permitting the doubling in the size of trains without exceeding draw-gear strength, through the use of mid-train locomotives.Westrail, Western Australia's government-owned railway introduced Locotrol working in 1996, also with retrofitted equipment. In June 2001 BHP Iron Ore in the Australian Pilbara set a record for the longest train with 682 ore cars and eight distributed GE AC6000CW locomotives in a 2-168-2-168-2-168-1-178-1 configuration. The Union Pacific Railroad, BNSF Railway are major North American Locotrol operators.
