Why didn't they keep it consistent? Whats the point of C gauge the to
the spur then slightly smaller B+ beyond? Its not as if C gauge trains
could head off onto the DC lines.

It means that in the future, if we build a north-south HSL that goes
via the KXSP complex, or if we regauge the existing mainlines to UIC C
for freight/double-deck trains, we won't need to spend millions on
regauging HS1 as part of the work. This is a Good Thing.

What I meant was , why didn't they make the whole line UIC C? Would
that extra inch or so on the rest of the line really have made so much
difference to the cost?
