"Creative accounting"
They must be using the same accountants that Amtrak uses to "prove" that the Northeast Corridor is "profitable", while all other long distance and corridor trains are losing shitloads of money. (They do that by moving a handful of NEC costs to other long-distance trains; e.g. the cost of removing snow from platforms on NEC stations miraculously showsup as a cost for the trains gointg to or originating in ... wait for it ... Miami.)
