As at 27/1/07 there were 7037 buses required to run the scheduled TfL

for swapping buses over during the day. Typically there is a 13-15%
margin for spare buses so the 8,000 value is about spot on.

Thanks, Dave & Paul C. The 13-15% to get from Peak Vehicle Requirement

www.londonbusroutes.net/details myself, in a post called "Bus route
statistics" on 17th January 2005. Hey, Paul G, why don't you Google
this:
