Not withstanding HS1, which is kind of like a closed, seperate railway, I was thinking something earlier. There's a temporary speed restriction between Tamworth and Elford in the Up direction due to a slipping embankment. Linespeed is 125mph, the TSR is 5mph. 5mph is the slowest TSR board available, so this must at the worst be the equal most severe TSR on the network. Any thoughts?
