This is the idea of Bob Brimley, so we will let him explain, though we would prefer to extend this to all forms of public transport photographs, not just buses. Here is what Bob says:

Given the number of photographers who are submitting their photos to the website I thought it would be a good idea to dedicate part of the site to enable them to showcase their images.

So what do you consider to be the top 3 best bus photographs that you have taken and why? It could be the vehicle, the composition, the memories it evokes etc.

I have sent in my top 3 and the reasons (although my favourite will probably be the next photograph I take)
