Hitachi is developing a battery-powered train in north-east England .

It replaces one of its diesel generator units with 16 lithium batteries.

This allows it to use up to 50% less fuel when running on lines with no overhead wires.

Siemens is also developing its own battery-only trains at its factory in Goole , Yorkshire .

The first train to rely solely on batteries went into service in 2016 in Japan .

UK experts say they could pose unique fire safety challenges.

Hitachi ’s train uses Nissan Leaf cells, which have been involved in 16 fires in the 14 years they have been used in road vehicles.

This is out of more than 500,000 cells that have been sold worldwide.

When lithium batteries are corrupted, they can experience thermal runaway meaning a cell undergoes uncontrollable temperature rises, making a fire hard to control.
