Did fog affect coaches?

[notadriver]

Does anyone know if coaches ran late due to the recent fog ?

I'm sure they did.

Commuter services were certainly affected. A general slowing down of traffic, poor visibility and the associated accidents when people fail to take conditions into account invariably have an effect on timekeeping.

As an example, the M2/A2/A102 got no higher than 40 mph for most of the way between Gravesend and the Blackwall Tunnel for the last two days, and had significant sections quite a lot slower (i.e. 4 mph) than that.

0100 Plymouth to London M6 Megabus was 15 early into London the other day, despite some heavy fog en route! :P
