Some thoughts on the following would be most helpful. Thank you in advance. My journey was from Hayes and Harlington to Old Hill, 20th March, for which I used contactless from Hayes and Harlington to Paddington (GWR), Paddington to Marylebone by tube then held an advance ticket for the 14:10 Chiltern Service to Birmingham (then local LM services to Old Hill to complete my journey). I boarded the 13:10 GWR service at Hayes and Harlington which became severely delayed between Southall and Ealing Broadway due to a failed Heathrow Connect service sat at West Ealing (so Im told). The driver announced that he had been instructed to change ends and take us back to Hayes and Harlington to switch to the main line and take us into Paddington that way, which is what happened. Essentially, we arrived at Paddington 63 mins late http://www.realtimetrains.co.uk/train/C20960/2017/03/20 I therefore missed the train at Marylebone for which I had an advance ticket but Chiltern quite happily endorsed my ticket for the 15:10 so nothing lost there but 1 hour of time. I have two questions: 1. Did Chiltern endorse my ticket because theyre obliged to or because they used discretion? 2. Do I have any recourse to make a claim for my delay between Hayes and Harlington and Paddington? I'm particularly interested because I used contactless.
