EspañolELECTRO-DIESEL LOCOMOTIVE
An 'Electro-diesel locomotive' (commonly referred to as 'dual-mode locomotive') is a special type of locomotive that can be powered either from an electricity supply (i.e. as with a straight-electric "juice jack") or from an onboard diesel prime-mover. For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose.
===France===
More recently, Bombardier has built dual-mode variants of its AGC series for the French operator SNCF; the electricity is collected by means of a pantograph in these units.
★ B 81500 – multiple unit trains using 1.5 kV DC catenary, in service since 2005
★ B 82500 – multiple unit trains using both 1.5 kV DC and 25 kV AC catenary, currently still being built
===Russia===
In Russia, a number of electro-diesels were built which featured both pantographs and diesel motors; these locomotives were actually multiple-units, with distinct electric, diesel, and motor sections. These included:
★ ED16 (ЭД16), ED18 (ЭД18), and TEU1 (ТЭУ1) narrow gauge models
★ OPE1 (ОПЭ1), OPE2 (ОПЭ2), NP1 (НП1), PE2(M) (РЭ2(М)), and EL20 standard-gauge locomotives used mostly in quarries
===United Kingdom===
Only two types were built; in both cases, their electricity source was a 750 V DC third rail.
★ British Rail Class 73, dating from 1962 – the more successful design, with some still in regular use. They have lower power output in the diesel mode.
★ British Rail Class 74 – rebuilt from British Rail Class 71 electric locomotives in 1967 and withdrawn by 1977.
===United States===
In the US, three dual-mode locomotive types have been built. These also operated off a 750 V DC third rail in electric-only mode. The primary function for these models is to provide a one-seat ride between diesel territory and the New York City terminals (Grand Central Terminal and New York Penn Station), which have ordinances prohibiting locomotives from emitting smoke within the tunnels. See Metro-North Railroad.
★ EMD FL9 – primarily diesel-electric, third rail electric mode for short-term use only; nearly (2006) retired from passenger service
★ P32AC-DM – dual-mode version of the GE Genesis, electric mode only used for first 4 miles of travel.
★ EMD DM30AC – specific to the Long Island Rail Road
★ Biodiesel
★ Global warming
