For a change we decided to catch the train to Gatwick airport instead of crawling round the M25. Got on at North Camp for the hour’s journey - it was a small unit of 3 carriages and it started to get crowded as travellers got on at Guildford and other stations along the line - as you might expect on this service there were a lot of cases in the corridor. At Redhill you can either stay on the train whilst is stops there for 5 or 10 minutes, or you can hop off and join the faster train which leave a few minutes earlier - too be honest it’s easier to sit and wait, as did most passengers. Have to say seats are hard and uncomfortable - wouldn’t have wanted to undertake a long journey sitting in them. Strangely, the guard came round and asked if anyone wanted to purchase tickets but never checked any.
