Good to see the data being released, But.... 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). Not much guidance is given for when a plan has reached a status that fits with the 'proposed' tag. I'd hope everyone would agree that to map *any*proposal, whatever the source, would be ridiculous.
I've only added one 'proposed' route and that was in winter 2011. The route was South Devon Link Road [link<http://www.openstreetmap.org/?lat=50.4974985122681&lon=-3.59270095825195&zoom=14>], was proposed in the 1950's, but constantly been put to the back of the queue. Last summer as the likely hood of it happening started to increase I looked at the 'proposal' tag wiki page for the first time, and it wasn't much help. Looking at the 50 years of setbacks this route suffered I think it demonstrates a route must be "likely certain" to proceed before it's added to the map. For the UK I think this means two tests 1. The proposal has, at least, outline planning permission 2. The proposal has funding in place 3. The proposal is also likely to proceed. (eg Developer hasn't pulled out) So for the South Devon Link Road, I added it this winter after (1) It had planning permission, (2)Funding had been allocated and (3) the local authorities have announced it they'll now proceed with the project. The HS2 had funding in place (although is reasonable to be cynical about spending allocated to future governments), and is likely to proceed, but it does not have planning permission. Therefore I believe the HS2 route should not yet be added. Many active mappers of OSM, including me, have some level of bias in favour of high quality transport networks, but we shouldn't let that impact on how we choose what's added to OSM. All the above doesn't change the fact that the current 'proposed' tag is very generous and would appears to allows adding proposals that will not happen.
