About I am suggesting the full length of the West Anglia Main Line from London Liverpool Street to Cambridge, I am also including the Hertford East Branch and Sansted Airport Branch. In total, all the lines would be about 71.9 mi (115.7 km), including the branches. Current operators are Greater Anglia, London Overground and CrossCountry. This is the London overground map the only section on this map I am recommending is the section from London to Liverpool and Stratford Street to Chesshunt and Hertford East both via Tottenham Hale. The trains below are ran by Greater Anglia Cross Country also 1 train every 2 hours between Stansted Airport and Birmingham but for us it only goes as far as Cambridge. Rollingstock Class 170 "Turbostar" (CrossCountry) Class 710 "Aventra" (London Overground) Class 720 "Aventra" (Greater Anglia) Class 745 "FLIRT" (Greater Anglia) Class 755 "FLIRT" (Greater Anglia)
Would it not be worth missing Hertford East but then going up to Kings Lynn giving the 755 playable services, the 387 playable services and the 170 services being a bit longer, also the lengthened GA services
