GTR had a pretty shoddy Monday for what feels like a weekly ritual and/or an unkind joke at the expense of hard pressed commuters, who regularly face a Monday morning slog to work. This Monday 11% of all GTR trains were either delayed for over 30 minutes or cancelled, whilst 31% were delayed by more than 5 minutes. Meanwhile, the Gatwick Express suffered an eye watering - or perhaps patience bursting - 29% of trains either delayed for more than 30 minutes or cancelled, whilst altogether 55% were delayed by 5 minutes of more. Monday also saw troubles on the Brighton Mainline, which had 50% of its services delayed by over 5 minutes and 18% delayed by over 30 minutes or cancelled.
On the upside, if one just considers raw statistics, things were not as bad during the rest of the week...but I'll leave it to your good judgements to decide whether this was indeed the case or not!
