The facility at Hatfield station in Hertfordshire features 27 charging points.
Charging provider Pod-Point worked with Govia Thameslink Railway (GTR) to create the facility, which increases public chargepoints in the Welwyn Hatfield region by 150 percent.
Hatfield was chosen following a heat-mapping exercise to find EV ownership and sales hot-spots.
Pod-Point says the installation will now serve as a blueprint for EV charging across the railway industry.
It will also help make electric car ownership more viable to those who don’t have off-street parking.
“We’re taking great strides toward our goal of having one of the best electric vehicle infrastructure networks in the world,” said Grant Shapps MP.
“This means a network for current and future electric vehicle drivers that is affordable, reliable, accessible and secure.
“Today’s landmark announcement ticks all those boxes and will make journey son road and rail much greener.”
GTR has also installed another 12 EV charging points at the Haywards Heath railway station.
They are in addition to 114 existing chargers across the GTR network.
Pod-Point now has the largest network of railway station EV chargers in the UK.
