Why 80xs? They are 125 mph (or 140mph if necessary) trains so where would they be able to reach anywhere near that speed? They would take 20 minutes to get to Stevenage, then slow down for Hitchin, followed by another 30 minutes to Cambridge (which at 26 miles is less than 60mph). What a waste that would be when an over 20 year old outer suburban commuter EMU could do the same journey in exactly the same time. This obsession with Inter-city status in some towns/cities is ridiculous. Maybe those settlements calling for it should pay the difference in cost as they think it will benefit them so much. Even Her Majesty goes to Sandringham on a class 365 so why is it not good enough for the oh-so important visitors to Cambridge?
