The High Speed Two Railway Route was published 15 November 2016 on the Governments Web Site just click the links.
Click here for the Long Eaton to Trowell section. There are two options, a High Level or a Low Level so is as yet there is some element of uncertainty.
There are four maps illustrating the route from Trowell to Tibshelf. To find the route from Trowell to the A610 you need this document – HSL13A Preferred Route Sheet 1 of 4. It does appear that the plan indicates a cut and cover tunnel by Strelley Hall. The M1 Motorway and the HS2 Railway Line converge for some distance. There is some writing giving some explanation but as I enlarge the words they become pixelated and difficult to read.
