A brief update as I currently have no Internet connection.
Following the earlier bovine incident, trains seem to now be running.
The railway company are clearly doing their best to get everyone home.
The passenger experience has been bad and there are many grumbles, particularly from those who were stranded at Gerrards Cross.
It'll be interesting to see how the overnight recovery goes. Trains will be all over the place and there is supposed to be engineering work taking place.
