A commuter train from Surbiton to Waterloo was late every day for the last three months of 2015.

The 8.31am weekday South West Trains service was more than a minute late consistently from October to the end of December, according to Network Rail figures analysed by the Labour Party.

The party also found overall passenger satisfaction for South West Trains has fallen from 87 per cent in autumn 2010 to 80 per cent in Spring 2015.

Sadiq Khan, Labour candidate for Mayor of London, said: "The Tories have been in Government for six years and City Hall for eight, yet they’ve done nothing to sort out London’s worst commuter routes.

"Only by giving the Mayor the power to decide who runs our trains and to insist on high standards of service can we get a grip of the situation and get a better deal for London’s train users.

"The repeatedly poor service is a daily headache for thousands of Londoners, and also bad for London’s economy."

Commuters take to social media daily to report gripes and frustrations with the services from Surbiton into London.

A South West Trains spokesman said: "We operate one of the busiest railways in Europe with nearly 1,700 services per day. This includes nearly 30 trains from Surbiton to Waterloo between 6am and 9am with a service departing roughly every 6 minutes and so singling out one service is clearly misleading.

"In addition, over the more representative period since April 2015, 95 per cent of these services arrived at Surbiton within four minutes of their scheduled time. Furthermore, 94 per cent departed within four minutes and 87 per cent arrived at London Waterloo within that time frame.

"Punctuality figures represent the combined performance of train operators and Network Rail and the largest programme of investment for decades is already underway on this network to catch up on historic under investment which has affected reliability."

Transport for London announced yesterday that it will take over London's entire suburban commuter rail network.

The first route to be re-branded within the London Overground will be Southeastern's, in 2018. Southern, Thameslink and Great Northern will follow in 2021.

Transport for London announce takeover of London's suburban rail services

Richmond Park and North Kingston MP Zac Goldsmith, Conservative candidate in the mayoral race, said following the announcement: "Millions of people who live and work in Greater London rely on suburban rail services. Too often those services are not reliable or frequent enough because they’re not accountable to the people who actually use them.

"By giving the mayor the power over these services higher standards can be set and improvements delivered."
