Could you or somebody else explain if what is referred to as the West Anglia side is the line from Liverpool Street/Stratford to Cambridge/Kings Lynn via Bishops Stortford?
If that is so, I find it a bit odd that it is given the West Anglia moniker, as when I was at primary school many years ago, Hertfordshire, Essex, and Cambridgeshire west of the River Cam were never part of the former Kingdom of the East Angles/Anglia (which contained Norfolk, Suffolk, and the eastern side of Cambridgeshire east of the River Cam).
Or did I have a rubbish geography teacher back then?
