ANGRY rail passengers claim a carriage which feels like a "sauna" has yet to be fixed despite months of complaints.

Irritated train users have been reporting the heating fault on c2c's carriage 67771 to the rail operator since April.

But despite the constant complaints, passengers say the faulty carriage is still running on the line between Southend and London Fenchurch Street.

The fault has led to heat blasting out of an air conditioning unit in the carriage, even at the height of summer.

Last week, commuter Hayley Walker tweeted c2c, saying: "The heating is on on the 8.02am from Benfleet in carriage 67771.

"Please turn the air conditioning on as it's boiling."

A similar tweet from Laura Sherlock on a train leaving Westcliff on August 5 reported a fault in the same carriage.

She said: "It's too warm for heat".

Several tweets from sweaty commuters in May, on what had been the hottest day of the year so far, described the carriage as "like a sauna".

A passenger who travels regularly from Laindon to Fenchurch Street, who asked not to be named, added: "They don't seem to be doing anything about it.

"It is not difficult to have something at a constant temperature."

A c2c spokesman confirmed the company was aware of the problem and was addressing this issue.

He added: "We would like to say sorry to everyone who has had an uncomfortable journey due to this problem, which affects one area of seating in this particular carriage.

"Our suppliers are awaiting a crucial part which will provide a permanent solution to this issue.

"In the meantime we are applying an alternative short-term fix, on a regular basis which means that the air conditioning does still work properly during on most journeys.

"We'd also like to thank our customers for reporting details whenever the air conditioning is not working satisfactorily.

"This information is crucial, as this allows our team to assess the affected carriages much more swiftly, and to carry out repairs."

This is not the first time there has been issues with the temperature on c2c trains, with hot and sweaty commuters again taking to Twitter to complain after the air conditioning failed on July 19, what had been the hottest day of the year.
