Disruption on Plymouth rail line this morning
Rail passengers travelling from Plymouth were subjected to disruption yet again this morning.
Safety checks had to be carried out on the line between Plymouth and Newton Abbot, near Marley Tunnel, closing the line.
A spokesman for First Great Western said: "The line was closed to Eastbound services for approximately 40 mins between Plymouth and Totnes. We continued to run services east and west of those points. The line reopened at 11.10am."
Replacement bus services were supplied in the meantime.
A spokesman for Network Rail said the closure was put in place after reports of something falling from the roof of Marley Tunnel. "That's something we take very seriously. But it turned out it was what we call spalling, which is when a few flakes of concrete have come away. It has no effect on the structural integrity of the tunnel itself and we have reopened the line because it is completely safe. At some point in the near future we'll re-line the tunnel, that's routine when things start to get a bit old."
