Network Rail has announced that the stretch of rail between Banbury and Leamington Spa will reopen next week after it was close by a landslide on January 31.
More than 350,000 tonnes of earth had to be removed from the line, which carries more than 130 freight and passenger trains a day between Birmingham and London Marylebone or Southampton.
Network Rail and its contractor J Murphy worked round the clock to repair the line, near Harbury, a few miles south of Leamington Spa and trains will begin running again on March 13.
Network Rail chief executive Mark Carne said: “Harbury cutting has suffered from landslips for more than 150 years. We have secured the cutting and made it safe and will carry out long term repairs which will significantly reduce the chances of similar incidents in the future.”
