As at 27/1/07 there were 7037 buses required to run the scheduled TfL
services on Mondays to Fridays when the schools are open. Note that this
figure does NOT include any spare buses that the operating companies own
to cover for repairs, damage, training or just to provide flexibility
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
to actual number of buses is very useful, because it's the bus garages
I'm interested in, and I wanted to find out how many buses they are
housing. Thanks very much for your efforts.

No thanks to Paul G for his rudeness. I'm surprised his Googling
skills did not reveal to him that I've previously recommended
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:
define: "humble pie"

Erm. Let's think (or not, I let the choice be yours). You asked a
question, I gave you an answer. You appear to have got the information
you wanted, by chance (due to the ever helpful and knowledgeable people
on this newsgroup), but if you had made your information request clearer
perhaps I wouldn't have posted what I did? Sure, sometimes I post short
retorts, especially when people ask lazy questions; it's about
considering other people's time too - not just your own. Dare I suggest
you do a google for a definition of humble pie as I can't see any
definition that fits? Preferably (from my perspective) you ought to do
course on how to ask a meaningful question?

I notice you didn't follow up on the suggestion that someone made of
doing a Freedom of Information request, which was the main cause of my
anger at keyboard. Lazy questioners I can deal with (I ignore them).
People who create work for others because they haven't done it
themselves annoy me intensely. Luckily the freedom of information act
recognises it and requests can be denied for various reasons, including
if the information is already available in the public domain.

I did notice that the responder said "if nothing else better comes
along", that's why my original post wasn't personal and was in the third
person. If you took it to mean yourself I can only suggest trying to
avoid the pitfalls I've outlined above and making reference to any
research you have done to avoid misunderstandings and potentially
wasting other people's time (like my own!).
