I'm on the Northbound Sleeper to Fort William, currently sitting at Birmingham International.
We were not supposed to be in Birmingham International this evening because a tree fell on the line near Penkridge, causing significant damage to the overhead electric wires. As a result, the railway is closed between Stafford and Wolverhampton whilst repairs are made. Hence rail replacement transport was arranged to take passengers to Crewe to join the train there.
However there has been a signalling error. The signaller at Rugby routed the train towards Birmingham rather than via the Trent Valley. The train had to proceed to Birmingham International and is currently awaiting a route conductor as the route it will take out of Birmingham is not the usual route, and the driver doesn't have the route knowledge for a small section of that route.
Currently +99.
