Are closely and efficiently monitored here:

I wasn’t amused to spend an hour this morning waiting for a bus that didn’t arrive. But I was amused after I gave up, went home and checked the Thames Travel website.

Please be aware there are severe delays to our services due to the amount of traffic congestion on the roads, we apologise for any inconvenience caused to our passengers but we are doing our up most to keep the buses running as close to their timetables as possible.

A vivid image. Some bus companies keep their buses running close to the side of the road. Thames Travel buses run close to their timetables.

And the rest.
