Hi All. I am looking for some help and advice on what to do. A few days ago, I bought a Gatwick Airport to Reading single, route via Gomshall. This is for travel on Sunday 4th February. I now see that the GWR website is saying that there is planned engineering work between Reading and North Camp with replacement buses, but it also says that due to industrial action, GWR trains will not run between Blackwater and Gatwick Airport (screenshot attached). As my ticket isn't valid via any other route (that I am aware), I cannot see how I can actually get home using this ticket. Given this situation, would this ticket be accepted along an alternative route, such as via Clapham Junction? I am unsure what to do, so any advice would be welcome.
