- First battery powered train operating a passenger service in the UK in over half a century
- Battery-driven BOMBARDIER ELECTROSTAR train entered passenger operation as part of a trial on British railways
Rail technology leader Bombardier Transportation is celebrating the launch of an Independently Powered Electric Multiple Unit (IPEMU), which can be driven entirely by battery technology, in addition to drawing power from its pantograph. Modified from an existing Stansted Express Class 379 ELECTROSTAR electrical multiple unit (EMU) train, the upgraded train is operated by Abellio Greater Anglia and is part of a research program partly funded by Network Rail and the Rail Executive arm of the Department for Transport. At the official trade press day, attendees were able to inspect the IPEMU, travel on it to and from Harwich International, and meet with specialists from Bombardier, Network Rail and other partner agencies participating in the project including Valence and Abellio Greater Anglia.
Working with industry stakeholders during a 7-month design phase, Bombardier reconfigured an ELECTROSTAR Class 379 train to enable the installation and integration of an operational traction battery system. The alteration required engineers to modify the carriage creating the necessary space in the underframe to accommodate the lithium iron magnesium battery cells.
Engineers also added high voltage and communications cabling, standard safety features and battery controls as well as integrated the traction and train control management systems. The new design uses existing line converter equipment to charge the batteries and connects the motor converters to the batteries when the 25 kVAC overhead line is not available.
In addition to its low noise and reduced energy consumption, battery operation’s main benefit is that it enables the train to cross non-electrified lines or can be used in the event of electrical failures without using overhead wire systems or diesel power. They can also use branch lines where it is not cost-effective to install additional overhead electrification as well as expanding rolling stock capacity by increasing the flexibility of existing diesel powered trains.
After a phased approval process and dynamic track testing, the train entered passenger service in January 2015 as part of a trial.
Per Allmer, Head of Western Europe, Middle East and Africa region at Bombardier Transportation said, “The IPEMU demonstrates what battery technology offers the rail industry. Following extensive design and testing work, the train has now successfully begun a trial passenger service, proving the viability of the concept. It’s a technology we can incorporate onto future new-build trains, such as our BOMBARDIER AVENTRA platform and retro-fit into existing modern rail vehicles, adding value to existing fleets.”
