Or why not simply have a public transport ticket that's valid on buses or trains?
A while ago I had purchased a 1st class ticket from Plymouth to London, in between purchasing it and the date of travel bustitution was scheduled due to engineering works (no-one told me, despite having bought the ticket via my
FGW▸ account), luckily I checked, so ended up doing half the journey on a rattly, smelly coach with no working toilet or catering facilities.........asked for a partial refund or compensation, was told I was entitled to nothing - so a first class ticket equates to a bus seat in FGW's book .
