This morning I bounced enthusiastically into the shower, out of the house, on the bus, to New Street, to the ticket machine, to the departure boards... only to see no trains to London. Apparently as part of the "West Coast Main Line Hash Up" there are replacement buses and alternative routes. So, given the choice of a 45 minute longer journey, starting from another Birmingham station, at some undetermined point in the future I got back on the bus and came home.
Rar! Decisive action ;-)
