I bought a Leamington-London Terminals Off Peak Super Saver Return (SSR) for travel as part of a split-ticket journey yesterday, for travel to Paddington via Oxford and Reading. This is a good value £19.15 with a railcard, valid "VIA BANBURY" to either Marylebone or Paddington and set by Chiltern. What with one thing and another I used the XC 1038 service, and this was offered by the TOC journey planners. But originally I wanted to travel earlier, and the precise restriction text (code PV) is: - not valid for arrivals at MYB or PAD before 1130 - not valid for arrivals at RDG before 1100 Travelling via Reading, the first train from LMS avoiding the second restriction is the 1000, arr RDG 1109 (and PAD at 1154). However I could not get any TOC booking engine to offer anything before the 1038 arr RDG 1140 (PAD 1214). Does anyone know why the 1000 from Leamington is not allowed?
