Hybrid Locomotives Overview of Construction Solutions

Application of hybrid drives in diesel locomotives

“…: General Electric ze Stanów Zjednoczonych, Railpower Technologies Corporation z Kanady oraz Toshiba Corporation z Japonii. Przedsiębiorstwa te, jako jedne z pierwszych, dzięki modernizacji starych spalinowych lokomotyw manewrowych i liniowych, wdrożyły do eksploatacji lokomotywy z napędem hybrydowym [2].…”

“…The leading producers of this type of solution are the following concerns: General Electric from the United States, Railpower Technologies Corporation from Canada and Toshiba Corporation from Japan. These companies, as one of the first, have implemented locomotives with hybrid drive to operation due to the modernization of old combustion shunting and line locomotives [2].…”

“…5). The modernized rail vehicle weighing 207 tons, in accordance with the initial assumptions, was supposed to save as much energy as it can be consumed by 160 households during the year [1,2]. Fig.…”

“…This allows to reduce fuel consumption by up to 15%, thanks to the use of accumulated energy with an additional power of 1470 kW (2000 hp). The technology used in GE Evolution Hybrid also allows to reduce the toxic gas emissions into the environment by 50% in comparison with the standard locomotives of this type [2,7]. The below scheme shows the hybrid drive system used in the GE Evolution Hybrid locomotive (Fig.…”

Application of flywheel energy storage for heavy haul locomotives

“…The characterisation of the main energy storage devices for railway applications can also be found in [6][7][8][9][10][11][12]. Battery, flywheels and fuel cell technologies are considered as a main energy source for all types of rail vehicles [8][9][10][11][13][14][15][16], and capacitors/super capacitors are generally used for light rail vehicles [16][17][18].…”
