Passengers on the London Overground are getting a slow service when it comes to complaints or making travel inquiries.

Responses on Twitter from the train company run by TfL can take around an-hour-and-40-minutes, by far the worst of any operator in the country according to a passengers' survey.

The Overground was way off track responding 40 minutes behind than the next worst which was Caledonian Sleeper services taking a sleepy one hour to respond.

The poll carried out by Callcare, a call centre and contact specialists, shunted 45 rail companies to the test and recorded their different twitter responses.

Some of the best operators, however, include c2c which runs the Fenchurch Street network through east London and south Essex, which has steamed into second best place taking just two and a half minutes to respond to inquiries, according to the survey.

But way out in front is Grand Central in the Midlands with an average response of just two minutes, out of the 48 Twitter feeds analysed.

Now the survey organisers suggest it might be quicker for London Overground commuters to make phonecalls instead!

Callcare's Gemma Harding said: "We'd suggest better practice (for rail operators) is to direct people to customer services telephone number to make sure issues are resolved. People have higher expectations for quick response times with Internet usage growing immensely over the last decade."

But some commuters wanting a speedy reply to inquiries about delays, refunds or available services just aren't getting it, including those on the Overground's East London line through Whitechapel or the Barking to Gospel Oak service.

A TFL spokesman, however, assured: "We aim to respond in a timely way including Twitter, which is just one of the ways people can get in touch with us."

{ It took TFL 23 hours to answer our inquiry about long delays responding!
