If you wish to detect which public rights of way (PROWs) are close to the 
route of the proposed HS2, my web site http://www.thehs2.com may help.

www.thehs2.com can be used to display a map showing:
    the route of the HS2;
    the PROWs that are close to the route of the HS2;
    the points at which these PROWs cross the route of the HS2.
The underlying map can be from the Ordnance Survey, OpenStreetMap, Google 
or Bing.

Examples are:
    Phase 1 (from London to the West Midlands):
       http://www.thehs2.com/phase1/maps/showmap.php?place=South%20Heath&type=rcOSM&lat=51.705&lon=-0.677&zoom=13
    Phase 2 (from the West Midlands to the North West and the North East):
       http://www.thehs2.com/phase2/maps/showmap.php?place=Culcheth&type=rcOSM&lat=53.45&lon=-2.52&zoom=13

Those web pages show a map from OpenStreetMap with various items 
superimposed on the map:
    a multi-coloured line that shows the route of the HS2;
    some cyan coloured lines showing the route of PROWs;
    some circles showing crossing points (i.e., where HS2 and a PROW meet).
You can click on any of these items to get more details about the item.

www.thehs2.com provides information about PROWs close to the HS2 as 
follows:
    Phase 1:
       Only for those PROWs which I've walked.  This is all but two of the
       crossing points between Euston and Offchurch (near Leamington Spa).
       Because of my GPS device, this data is inaccurate in places.
    Phase 2:
       Only for those PROWs where the council has released data about their
       PROWs.  This is actually most of the PROWs as only the councils of
       Manchester, Sheffield and Trafford are unable to supply data.

The data is also available in KML format:
    Phase 1:
       crossing points: http://www.thehs2.com/phase1/kmls/c/all.kml
                 PROWs: http://www.thehs2.com/phase1/kmls/r/all.kml
    Phase 2:
       crossing points: http://www.thehs2.com/phase2/kmls/c/all.kml
                 PROWs: http://www.thehs2.com/phase2/kmls/r/all.kml

The crossing points are also available in csv files:
    Phase 1:
       http://www.thehs2.com/phase1/kmls/c/all.csv
    Phase 2:
       http://www.thehs2.com/phase2/kmls/c/all.csv
In these csv files, the word "Fill" means "embankment" and the phrase
"At Grade" means "level with the nearby land".

So these maps/data may help you find the PROWs which cross the route of 
the HS2 that are missing from OpenStreetMap and so need some mapping done.
