To help reduce plastic pollution, Network Rail has now installed drinking fountains at eight stations in London.
They calculate that by the end of 2018, their refill points across the country will have saved up to 368,000 plastic bottles.
Andrew Haines, Chief Executive of Network Rail, said: “This is one of the many things we are doing to help our country become more sustainable. These small, but important steps, will help provide a healthier and greener future, for passengers and the planet.”
Members of the public have been posting on social media about the fountains. One Twitter user said: “I love this free water refill station at King’s Cross station. More of these please.”
Thames Estuary Partnership is a partner in the OneLess movement, designed to make London free from single-use plastic water bottles by creating a refill culture. Click here to find out how you can get involved.
