Just did a quick check on some of my profiles for the Coquihalla. Tunnel
widths there were something just over 18 feet in width and about 22 feet 4
to 6 inches from centre line of tunnel to top of rail. Tunnel walls
appeared to be around 16 feet vertical before starting curve to top centre.

Subject: [cpsig] Kettle Valley Railway tunnel dimensions
Am I correct that CPR tunnels generally were about 16-17 feet wide, and 23-24 feet tall?
I got this from looking at drawings for liners on the cpsig site -- 8' radius around the top, and 14.6 to the rail bed. Did CPR keep the unlined tunnels to these dimensions more or less?
