I was travelling from Stroud to Cheltenham today with my 13 month old. When the train pulled in, I raced with my buggy to the disabled carriage, only to be told that disabled is 'in first class' and 'isn't for you'.
After politely explaining that my baby would scream and/or slide down to walk about while the train was moving if he was not clipped in, a kind member of staff - Nick - allowed me to sit there and offered me free tea whilst chatting about his own toddler.
On the way home, the staff were just as lovely. They let me sit there with the buggy (thankfully as my son has just gone to sleep) and pressed a free coffee on me.
But the lovely staff were all breaking the rules. GWR rent these trains from Hitachi; the lack of buggy/disabled space in Standard class means they can make a bit of extra cash. But parents are forced to fold buggies or stand in the vestibule.
It's put me off going to London to see family over the holidays.
