I have bought a return ticket through London so I can break my journey back in London on Sunday.
I'm just looking at the trains back to Paddington and the usual 20 min journey from slough is replaced by a 1 and 1/2 hour bus replacement service, then a further train journey, which added on to the part where I get to slough makes the trip just back to London nearly 3 hours.
I would have taken a different route out of London if I had realised. Is there any chance I can use a different route on the grounds they aren't providing a reasonable service?
