This was a single tunnel, 244m long on the former North British Railway, now the East Coast Main Line.
During upgrade work to increase the clearance for larger containers the tunnel roof collapsed causing the deaths of Peter Fowler and Gordon Turnbull to whom the Penmanshiel Memorial is dedicated.
During the line^s closure trains were diverted over the West Coast Main Line via Carlisle.
The tunnel has been sealed and a new alignment has been opened alongside to the south west.
Just to the north of the tunnel, on the new alignment, the Southern Upland Way crosses the line.
