Well, since the cost of a round-trip ride on the Cog train is only $31 to $35, I'd say charging rescuees $100 for a ride down the hill would be more profitable. 911 would get the call, let the rescuee know when the next train is coming by, and let the Railroad folks know they will have some pickups and to get the money up front before letting them on the train, at least that's the way I'd do it. The railroad can do VISA, and who doesn't travel up Pike's Peak these days without their plastic?
