Railways after the election

[kudu]

To base the case for HS2 or HS anything on capacity rather than speed has an unfortunate drawback: that halving the speed would double the capacity.

... which would be disastrous if the competition where to be short-haul airlines and constant speed (i.e. driverless) trucks.

... in which case there is no capacity problem in the first place. This shifts the argument to averting a possible future modal shift to air or road. If that's the case for HS2, advocates should say so and not rest on spurious capacity arguments.
