Purchased train tickets from Cambridge to Axminster via trainline.co.uk three days before travel. Paid 200 GBP, but was theoretically able to reserve seats on the train out, so my three family members could all sit together. Day before travel (day after purchase) I get an email indicating there *could* be disruptions in travel due to a planned strike and encouraging me to download their app to help in the event of a train being cancelled. No specific information about our train though. Arrive in London following day to discover posters ALL OVER THE STATION indicating the strike has been planned well in advance and in fact, our train is cancelled. Check the app. No mention of any of this. Take to Southwest Rail staff, who inform me that this strike has been planned for some time, this train hasn't been scheduled to run since the strike was announced, and that Trainline regularly sells tickets for trains that aren't running. She kindly works with us to figure out how to get us to Axminster via another train AND BUS, which takes several hours longer. Had Trainline been forthcoming with this information in the first place, we wouldn't have booked the travel - or we would have found another way to get there before being stranded in London. When I contacted Trainline today to express my dissatisfaction, I was told repeatedly that it was not their fault that Southwestern Rail hadn't shared the strike information with them (which I do not believe given the very public nature of the information available in the Station) and that since Southwestern Rail *DID* get us to our destination eventually, I had nothing to complain about and no right to any refund from Trainline. To which I say, I will never be spending money on Trainline again.
