Recently it emerged that a Southern Rail train service had been delayed every day for a year, while thousands of commuters at London Bridge have faced disruption this year due to engineering work.
With that in mind here are the ten worst excuses given by public transport companies for delays to their services.
1 Leaves on the line
2 The driver getting lost
3 Toilet troubles
4 The bus driver falling asleep at the wheel
5 The grass being too long
6 The milkman not arriving
7 The driver having a sprained eyebrow
8 The wrong kind of snow
9 The staff being left in Cardiff
10 The driver's wife throwing him out and him having to sleep in the car
