First Capital Connect will roll out free Wi-Fi at Huntingdon Railway Station in the summer.
The station has been chosen as one of 17 key stations on the rail company's lines in a £2milllion investment.
David Statham, managing director, said: "This is all about giving people better value for money. Free WiFi at our key stations turns downtime into productive time for our busy passengers giving fast access to the entire net and features such as our mobile website and new mobile ticketing app.
"This £2m-plus investment will also give passengers cleaner trains, improved customer assistance, further measures to prevent graffiti and improvements to stations along the route.
"It builds on what we have already delivered over the past eight years of our franchise: almost 30,000 extra seats at our busiest times of the day, new stations at St Pancras, Blackfriars, King's Cross, Farringdon and West Hampstead, better stations, new or upgraded trains and a 36 per cent reduction in crime."
