Large diameter HS3 tunnels for speed and services

First published August 2014; updated August 2015

Wikipedia's London Underground shows how tube trains fit their tunnels so snugly that they almost act like pistons pushing air in front of them.


In comparison the new Crossrail tunnels are large enough for full sized trains to run at speed. HS3 tunnels could be larger still at relatively little extra cost, and the track raised to create better air flow and a useful space for additional services.



HS3 plays a natural part in Loose Ends, the second of the Buffalo Future novels, which is in proofing. Ideas are futuristic and realistic.
