20mph speed restriction in the twin bore Marley Tunnels

« on: May 16, 2012, 10:18:39 AM »

Since last Saturday there has been a 20mph speed restriction in the twin bore Marley Tunnels at the top of Rattery Bank in South Devon.Heard that some sort of subsidence of the overlying land has occurred hence the emergency speed restriction and that it could pose a longer term problem.When the original broad gauge single bore was built by Brunel I think it was built cut and cover as the nearby land owner did not want his view spoiled by passing trains could this be something to do with the current problem.

There was a bit of a subsidence scare on Friday, the tunnel was closed for a couple of hours on Friday afternoon while waiting for a tunnel engineer to attend and check it was safe.

The 20mph speed restriction on the down line tunnel has been lifted but remains in place on the up line tunnel.Have heard it could be a long term problem.
