I'm separating out the various sections (cutting, tunnel etc) to separate shape files and converting to lat/lon. I'll have a play with it in JOSM once done. I'm splitting with whatever the west side attribute is (the east side may be different where the natural ground slopes etc).
I'll put all the various files on dev once I'm done.

I don't believe this "proposed" route should yet be added to OSM. You'll regularly here the phrase "map what's on the ground", but we all(?) accept upcoming changes to "what's on the ground" can be mapped, and these upcoming changes to the land are mapped using the proposed tag (then construction tag). By that reasoning we wouldn't map boundaries, as these don't appear "on the ground", they are entirely abstract concepts. The point here is that this is *helpful geographical information*. If the proposal goes away or changes, remove the data. Let's be pragmatic here. I agree that one should not add every aspirational route, however this is much more than an aspiration and there is considerable support for it from official sources. I believe we should indeed add transport proposals where they have committed funding and official firm support. We should of course tag is as 'proposed'. If the project goes ahead we change it to 'consturction', if it goes cold then we delete it. Fyi, I did just that on the Tintewhistle bypass to the east of Manchester. I added it when it was funded and and in the HA plans and then removed it when the public inquiry collapsed a while later. It is of course up to map rendering script to determine if it is appropriate render 'proposed' transport schemes and this will depend on the use to which it is to be put. Mapquest probably wouldn't show them (because mapquest are primarily providing maps for the traveler. OSM Mapnik will probably show it because it tries to map almost everything. Other mapping outlets can make their own decision. Good news re rendering HS2 for use in Potlatch. One suggestion... I notice that the shape file contains details of cuttings, embankments, bridges (and viaducts) and tunnels. Could you present that using distinct colours or textures or something? It is tagged separately for each side of the route, ie eastside=cutting. Regards, Peter We also seem to mark routes of old railways for which there is no evidence on the ground. (Quite why, I don't know, and this raises the question again of representing any historical data, but that was discussed at length recently).
