A diagram which HS2 Ltd seems particularly fond of shows rail passenger growth, which they claim shows the need for a new high speed rail line.
Here’s the version as it appeared in the David Higgins’ HS2 Plus report:
But this is misleading as the passenger numbers do not start at 0. In addition it is all rail passengers, not just the passengers who use long-distance travel on the West Coast Main Line.
The picture is very different when one includes the data for long distance passengers, especially on the West Coast Main Line.
