In 1986, Czechoslovak locomotive manufacturer KD built a prototype hybrid shunting locomotive termed the DA 600. The locomotive was powered a 190-kW diesel engine and four electric motors, with a maximum overall power 360 kW powered from batteries. The batteries were recharged while the diesel engine was running, by regenerative braking or from external electric power.
After tests on the Railway test circuit Velim and some minor tweaks, the locomotive was lent to the Olomouc train depot and successfully operated there for ten years. Czechoslovak socialist economics failed to start mass production, mainly because of a lack of proper battery manufacturing capacities.
An example of a typical “hybrid” is the new Autorail grande capacit (AGC or high-capacity railcar) built by the Canadian company Bombardier for service in France. This has dual mode (diesel and electric motors) and dual voltage capabilities (1500 and 25000 V) allowing it to be used on many different rail systems .
In May 2003, JR East started test runs using a NE (New Energy) train, testing the system performance in cold regions.
The design had two 65-kilowatt fuel cells and six hydrogen tanks under the floor, with a lithium-ion battery on the roof. The test train was capable of 100 kilometres per hour (60 mph) with a range of 50100 kilometres (3060 mi) between hydrogen refills. Research was underway into the use of regenerative braking to recharge the test train’s batteries, intending to increase the range further.
JR had stated that it hoped to introduce the train into scheduled local service during the summer of 2007. This production version became the KiHa E200 diesel/battery railcar.
Since 1936, a fleet of London Underground battery-electric locomotives have been used for engineering work on the Tube system. These locomotives operate from either third rail, or their battery bank and can be recharged on the move.
A Sunday-service operated on the Stourbridge Town Branch Line for a period of two years, using a flywheel-based energy storage system built by Parry People Movers. In 2008, a pair of British Rail Class 139 railcars were ordered to provide full service on the branch line from 2009 onwards.
During 2007, a modified Class 43 power car ran on the Great Central Railway and then as part of the Network Rail New Measurement Train (a 200-kilometre per hour track-recording train). The Hitachi developed system used a battery-assisted diesel-electric drive system; the hope being that it would demonstrate a cut in emissions by up to 50 percent and a reduction in fuel consumption costs of 20 percent. The modified locomotive, named Hayabusa, was semi-permanently attached to a converted passenger carriage containing the battery bank during the testing period.
In February 2009, it was announced that Hitachi, as preferred contractors for the Intercity Express Programme (IEP) would deploy hybrid technology on the self-powered variants of the IEP trains. This trains would be capable of 200 kilometres per hour. Some hybrid-trains would also be bi-modal, allowing power to be taken from overhead lines.
In 1928, Kennecott Copper ordered four 700-series electric locomotives with on-board batteries. These locomotives weighed 85 tons and operated on 750-volt overhead trolley wire with considerable further range whilst running on batteries. The locomotives provided several decades of service using Nickel-iron battery (Edison) technology. The batteries were replaced with lead-acid batteries, and the locomotives were retired shortly afterward. Three out of the four locomotives were donated to museums and are currently displayed at Boone and Scenic Valley Railroad, Iowa, Northwest Railway Museum, in Snoqualmie, Washington and at the Western Railway Museum in Rio Vista, California.
A Green Goat hybrid shunting locomotive.
In 2004, Railpower Technologies, a Canadian company, began running pilots in the United States with the Green Goat shunting locomotives. The trials led to orders by the Union Pacific and Canadian Pacific Railways, starting in early 2005.
These diesel-electric hybrid trains are expected to cut emissions by up to 90 percent and to decrease fuel consumption by up to sixty percent, when compared to conventional diesel-powered locomotives. The “Green Goat” locomotives were intended to be used in marshalling yards.
General Electric (GE) put[when?] their hybrid locomotive on display at Los Angeles Union Station. The locomotive used regenerative braking and a bank of high-capacity batteries that GE was constructing to achieve its fuel savings and to achieve higher emissions standards than previous ordinary diesel locomotives. It was expected to join GE’s current line of GE Evolution Series locomotives. as of May 2007[update].
The city of Savannah, Georgia tested the operation of a W class Melbourne tram in service as a biodiesel fuelled hybrid with on board battery storage in late 2008. Regular service along the River Street Streetcar started on February 11, 2009.
