Only if they're going to be the only users of the service. I was
arguing near the beginning of this thread that the lack of other
users was a problem for the proposed Prague service, whereas a
similarly expensive line in Edinburgh could cover its costs by also
serving large business parks, a university, other transport hubs
and residents of much denser residential zones. Not many of these
local users are going to be using hardshell wheeled suitcases or
carrying skis, and many more will be disabled or want to take their
bicycles than is the norm for air travellers.
(I guess I'm not really disagreeing - the analysis still needs to
be as specific as possible).
