The Tyne Valley rail line - connecting Newcastle with Hexham and Carlisle - has closed again,. just hours after re-opening.
Network Rail says staff worked through the night to clear the line of 70 tonnes of rubble after a landslip in the Hexham area yesterday.
The line re-opened at 6am today - but closed again after a second landslide, just a mile from the first one.
This time 120 tonnes of rubble and trees needs to be cleared from the trackway.
At this stage it is not known how long the work will take.
The landslip, which caused part of the Carlisle to Newcastle rail line to close, is expected to re-open fully on Monday, February 8.
The massive landslip which caused part of the Newcastle to Carlisle rail line to close for the last month, has finally been cleared.
Engineers say they hope a section of the Network Rail line between Prudhoe and Hexham blocked by a landslide could reopen in a month
