As the charger is supplied by a third party and added to their network of public charge points (perhaps with limited access hours), assume the user is charged something like 60p/kWh. The railway is supplying the juice, so the agent is going to be paying something like cost plus 20%. Potentially as a large user of sparks, the railway is on a spot contract with kWh cost changing quite often.
The car owner is contracting with the charge point provider via their app so any gaming of the free 15 mins is the charge point provider's problem. The railway is still being paid for the electricity consumed and making a profit.
Of course, if the railway hasn't set up the contracts in that way, then it ain't no way to run a railway.
