Actually muppet , I was thinking of the current Thameslink line to
bedford, but feel free to keep smiling. Oh , but if the power supply is

Milton. This makes it almost (but not quite) impossible to run 8-coach
trains North of Cambridge.
Actually you could run any length of train you wanted , since as a great
