[Talk-GB] High Speed 2 route mapping

The proposed routes are in OSM. There is a relation for each phase of HS2. See:

Phase 1: https://www.openstreetmap.org/relation/1986960

Phase 2a: https://www.openstreetmap.org/relation/6748946 

Phase 2b western leg: https://www.openstreetmap.org/relation/6775224

Phase 2b eastern leg: https://www.openstreetmap.org/relation/6775258


Note that 2b eastern leg does not reflect the latest proposed alignment as I’ve yet to see a shapefile for that.

I don’t expect any significant changes to proposed 2b western leg.


These relations are based upon the alignments (shapefiles) as published by Gov/HS2 and predate hybrid Bill, therefore we can expect tweaks and modifications to the details once main construction commences.


I recently added Vesting Declaration interests for all Phase 1 areas to that relation except I think I still need to do Camden which is mostly the Euston block which is mainly under demolition anyway. Some construction areas are mapped by me or by locals and I’m familiar with most of the construction related requirements of phase 1. Note that some current construction work areas for phase 1 are only for enabling works (utility diversions etc.) so expect construction areas to change over 2019 and into 2020.

Main contractors who will build phase 1 are not now expected to commence main site works until the first quarter of 2020.


It would be good if locals in the greater London area can keep an eye and update construction areas, especially at Euston and at the tunnel vent shaft locations out to Ruislip.


The new HS2 sliproads off the M25 at Chalfont could do with a clean up to their proper alignments when some form of access or aerial imagery is available.

Subject: [Talk-GB] High Speed 2 route mapping


I'm doing some professional work with High Speed 2 data.


Can anyone update or add detail to https://wiki.openstreetmap.org/wiki/United_Kingdom_Railways/High_speed_2 ? I know that @blackadder worked on this.


I've also been looking at http://www.thehs2.com/


I also know that there are now some active (pre?) construction sites on the route which could be mapped.


....and, is there any advice or links to discussion on the addition of proposed railway lines?
