This first electrification system with GE-built boxcabs were the only three-phase AC power ever used on North America railroads, see Three-phase AC railway electrification. The electric boxcabs pulled trains through the tunnel with their steam locomotives still attached until they were retired in 1927.
Railway electrification is the development of powering trains and locomotives using electricity instead of diesel or steam power.The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin, London, and New York City.
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive (or a generator car) at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs.
[citation needed] Electricity consumption fell in Denmark only 4% in the 2009-2008 recession (while falling 7.1% in Sweden, 7.9% in Finland and 8.6% in the UK; in Iceland consumption fell only 0.9%). Danish average consumption of electricity per person was 0.8 MWh less than the EU 15 average of 7.4 MWh in 2008. [11]

So, even with the addition of 28 high-speed trains purchased in 2016 with $2.45 billion, it won’t be until 2035 that even 30 percent of the route offers up speeds worth talking about.
SNCF Class B 81500, an example of an electro-diesel multiple unit. An electro-diesel multiple unit (EDMU) or bi-mode multiple unit (BMU) is a form of a multiple unit train that can be powered either by electric power picked up from the overhead lines or third rail (like an electric multiple unit – EMU) or by using an onboard diesel engine, driving an electric generator, which produces ...
Exceptions include: Saltsjöbanan and Roslagsbanan (1.5 kV DC), the Stockholm Metro (650 V and 750 V DC) and tramways (750 V DC). The Oresund Bridge linking Sweden and Denmark is electrified at 25 kV, Danish standard; the split is located on the Swedish side near the bridge. Only two-system trains (or diesel trains; rare) can pass the point.
