Delays 1: Rail replacement bus

Lovely final morning in London meeting a uni housemate of Adams. Then sadly the end of our holiday and time to head home. Since the train line was washed away last week we had a huge chunk of the journey to complete by bus from Bristol. All going very well until coming to a standstill 10 mins before Plymouth due to a multi car pile up just ahead of us. We sat there for over 1.5 hours - and to make matters worse the coach toilet was not working. Was very glad to finally get back!
