Ireland Is Ready to Bet Big on Battery-Powered Trains

In an effort modernize its rail system, the country is looking to a technology it pioneered in the 1930s and ‘40s.
From 1932 to 1949, Ireland ran one of the earliest battery-powered train lines, from Central Dublin to the beach town of Bray.

Ireland’s quest to modernize its train network could soon make it a global leader in battery-powered trains.

National carrier Iarnród Éireann launched its request for proposals last week to purchase 600 new train carriages by 2040—a near-total overhaul of a fleet that currently contains 629 carriages nationally. All those new trains would run on electricity, and up to half could be powered by batteries. That would represent a remarkable transformation for a network that today runs largely on diesel.
