Great Western Railway’s innovative FastCharge battery trial has achieved another significant step – just days after laying claim to a battery train UK distance record without recharging.
The train demonstrated its capability on the Cotswold Line by travelling a UK record of 86 miles (138km) on battery power alone and without recharging.
The Class 230 battery train completed a 70-mile move from Long Marston to Reading Train Care Depot – using just 45 per cent of its battery capacity. GWR’s team of specialist engineers on board the train claim it could have travelled more than 120 miles on a single charge.
GWR’s FastCharge technology has been designed to solve the problem of delivering reliable, battery-only trains capable of fulfilling timetable services on branch lines, eliminating the use of diesel traction and helping to meet the Government and wider rail industry’s target to reach net-zero carbon emissions by 2050.
The use of batteries for extended operation has typically been constrained by their range and meant widespread implementation has, until now, not been possible. It also negates the need for overhead electric lines which are expensive, time consuming to install and impact the landscape.
At West Ealing, where the technology will be trialled in a real-world environment for the first time this spring, the train will charge for just 3 ½ minutes before restarting its journey on the Greenford branch line.
GWR has already carried out simulations on other branch lines in the Thames Valley to explore how it could be rolled out even further in the future. This could reduce GWR emissions alone by over 1,700 tons of CO2e per year.
It is hoped the technology could one day see battery-powered trains in operation across the UK’s approximately 2,000 miles of 80-plus branch lines.
