I read recently that the Midland Mainline is being upgraded to 125mph in places. I know the Turbine Powered APT did London-Leicester in 58 minutes in the 1970s doing 125mph. I'd imagine they will get London-Leicester to about 60 mins, Sheffield in 2hrs should be possible. How much is the projected cost? Which stretches are suitable for 125mph? Has the work started and when is it due for completion? I don't know the line that well but think London to Bedford and Leicester to Derby would be suitable for 125mph.
