Planning changes to the phase 1 route of HS2 have been agreed by the Department of Transport (DfT), after a number of appeals were raised during a House of Commons Select Committee review.
The improvements will mean that fewer properties will be affected by the development of the line between London and Birmingham.
The new safeguarding directions include the preservation of 30 acres of woodland in the Chilterns with a 1.6 mile extension into a deep bored tunnel under the hills.
Also allowing the realignment of the route near Lichfield to allow the railway to pass under the A38, the West Coast Main Line and the South Staffordshire Line, rather than run over them on viaducts and make to crossings over the Trent and Mersey Canal.
The directions serve to both protect the land required for HS2 and to trigger statutory compensation arrangements for the affected homeowners.
