Going Underground blog we can now see the big picture - of what a combined new circle line plus overground is going to mean for the Bush and west London in general. Much better connected is the answer.
I remember before I moved to the Bush I had to travel there from Golders Green in North London. A journey that takes about 15 minutes on the north circular by car took over an hour because of having to travel right slap bang into Tottenham Ct Rd to change onto the central line.
On my travels I see orbital lines of various types on metro systems all over the world - and I suspect I won't be the only one who can't wait for us to get plugged in like this as soon as possible.
