Τα ηλεκτρικά τραίνα συνήθως τροφοδοτούνται από εναέριο αγωγό επαφής, αλλά η Network Rail η εταιρία διαχείρισης της σιδηροδρομικής υποδομής των Βρετανικών Σιδηροδρόμων πιστεύει ότι τα ηλεκτρικά τραίνα που μπορούν να κινούνται με μπαταρίες θα μπορούν να εξυπηρετήσουν σε γραμμές όπου δεν συμφέρει η εγκατάσταση ακριβής υποδομής ηλεκτροκίνησης.
The first battery-powered train to run on Britain’s rail network in over 50 years carried its first passengers in January 2015. This achievement marked an important milestone in the drive to demonstrate the viability of an eco-friendly, battery-powered train for the 21st century
Electric trains normally take their power from overhead cables but Network Rail, the company responsible for the nation's rail infrastructure, believes that independently-powered trains could be used to bridge gaps between electrified routes.
They could also be used on branch lines which are not cost-effective to electrify.
It is hoped the trials could ultimately lead to a fleet of battery-powered trains running on Britain's rail network, which would be quieter and more efficient than diesel-powered trains, making them better for passengers and the environment.
The project, first announced a year ago, is being funded by Network Rail and the Department for Transport. It has the backing of Bombardier, train operator Abellio Greater Anglia and technology partnership FutureRailway.
The train being used for the test is a four-carriage Bombardier-built Class 379 Electrostar, constructed at Litchurch Lane and leased to Greater Anglia.
