Part of a £70 million fine to be issued to Network Rail will be spent on introducing and improving wi-fi services on busy commuter trains, it has been announced.

For train routes which already have available wi-fi, the internet speed is expected to be increased by at least ten per cent, reports bbc.co.uk. South West Trains, Southeastern, Gatwick Express and c2c do not currently offer wi-fi to passengers but will be able to do so in the near future.

Network Rail is being fined by the Office of Rail Regulation for poor punctuality, although many believe there is no point as it will only take away funds which could be used to improve service. Ministers are now pledging the cash to help passengers connect when travelling.

Transport Secretary Patrick McLoughlin said: “We all know how frustrating it can be to have our phone calls and internet use constantly disrupted by poor signal while travelling on trains.

“At the moment it happens too often. Passengers expect and deserve better and with these plans, that is what they’ll get.”

Train routes set to enjoy free wi-fi for the first time include many from Portsmouth, Brighton, Manchester, Bedford and Sheffield. Although train firms will have to pitch in order to get a share of the money, the busiest commuter lines will be given priority, reports independent.co.uk.
