I have just seen London's proposal for the "Superloop" express bus network. I believe it is separate buses rather than one bus but it just got me thinking about the outer circle 11A/C. The journey I make tends to take 55-60 minutes on the bus, whereas the car journey takes 18 (via a quicker route). I know that taking the 11 for me is always unappealing due to the long nature of the route. With its curtailing due to reliability issues too, I know some passengers are unhappy with changing at Acocks Green. I am curious as to how popular an express circular route would be. The route would not necessarily be the same, but instead more directly link key areas like Acocks Green, Kings Heath, Selly Oak, Perry Barr, Erdington etc. Surely this would be attractive to passengers who could easily travel around outskirts without having to go via city centre or go on the excessively long circular journey. After all, not everyone travels from the city centre! The 11 is obviously very useful and the stops between areas are well-used, but an X11A or X11C (horrible numbers!) would surely benefit people who want to make a more direct journey between outer areas.
