it's not a subsidy if it's a user-pays system. A subsidy is only a subsidy if users don't necessarily pay the full cost, and the rest is borne by some other group of people who _don't_ use the service.

Other example, people who rarely take the train still benefit from rail infrastructure (freight, reduced congestion etc). Is the rail network subsidized?
