The Hertford East branch line, and Lea Valley lines, are both in which country?
Lea Valley lines The Lea Valley lines are two commuter lines and two branches in North East London, so named because they run along the Lower Lea Valley of the River Lea. They were part of the Great Eastern Railway, now part of the "Anglia Route" of Network Rail.
North Warwickshire Line The North Warwickshire Line (also known as the Shakespeare Line) is a suburban railway line in the West Midlands region of the United Kingdom. It runs from Birmingham to Stratford-upon-Avon, Warwickshire, now the southern terminus of the line, although until 1976 the line continued to Cheltenham as part of the Great Western Railway route from Birmingham to Bristol.
