We're in a bit of a sticky situation here at Ashchurch for Tewkesbury. There's a 42 bus to Cheltenham that departs at 1926, yet our train only arrived at 19223, and the rules do say that we need to allow at least a five minute connection time where it is not stated, so that marks that bus out. It is also the last bus of the day.
Staying on the rails, the only departures in the next two hours both only go to Worcester, otherwise there is a 2202 south to Bristol, but that's over the two hours permitted at any station.
I would rather take the 2202 as I think heading back to Worcester is stupid, but in order to comply with the rules I think we have no option other than to board the 2011 First Great Western service 2E27 back to Worcester Shrub Hill, arriving there at 2027 on Monday evening.
