There never been a 19:58 Haywards Heath to Cambridge service or is this something that's happened due to covid?
If you wish to get on a train to Reading, officially you need to get the 19:50 and have a 29-minute wait at Gatwick Airport.
That's 9 minutes longer than some of the time savings I have previously read about when they talk about speeding up train services.
As it is, I am taking my chances on the 20:12. That isn't an official connection at Gatwick Airport, as you only have 6 minutes to change trains and that isn't long enough.......officially.
Update: As it transpires, due to trespassers they cancelled the Gatwick Airport stop on the Gatwick Airport to Reading service.
There is a 20:32 to Redhill but no 21;00 services so will have to wait until 21:43. Had this occurred last week I could have got the 19:53 but because it's very essential that skips Haywards Heath now and I didn't make the 19:50, I had to get the 20:12. Last week I could have got the 20:19 Peterboriugh service and I'd have been ok. Oh well it's not often this happens.
I even arrived into Gatwick Airport before the incoming service from Reading was due to arrive but 10 minutes is 10 minutes.
My ticket isn't valid via Clapham Junction and there was no ticket acceptance. I bought my particular ticket as it was cheaper. So one must accepts the consequences of doing so. I could have paid extra to change my tixket but I decide to sit it out instead.
