Passenger numbers have risen by 84 per cent on London Midland’s Rugby to London service after it was made quicker.
The announcement follows the introduction of 110mph trains on the route, which have cut journey times between Rugby and the capital by 34 minutes, as well as introducing an additional hourly departure to London.
Some 40 new carriages are due to be delivered in 2014 as part of the company’s plans to run extra and longer trains on the route.
London Midland’s head of marketing, David Whitley, said: “The impact of these reduced journey times has exceeded all expectations. We inherited a service that was barely surviving five years ago – today we’re looking at ways to run longer trains to meet demand. That’s a great place to be.”
The Government ordered London Midland to compensate passengers in December following hundreds of delays and cancellations.
