The stupid thing is that those business travelers won't use the rail line, they'll happily chug along in their self-driving Teslas and ultra comfy Audis/Mercedes/BMWs.
Toronto just dealt with this. We built a rail line that goes from our international airport right into the heart of the downtown. The plan was that business travelers could get off the plane, get on the train, and go right into the city without a car. Nobody uses it. They forgot about the comfort of the taxi and limo - you don't have to carry your luggage and you don't have to share the car and listen to screaming children.
