1 minute ride, the train loops every 2 minutes. So if you miss it no worries it'll be back in 2 minutes. Best way to enter and exit airport is via that train, no congested terminal traffic.
Aprox 1 o 2 minutes, good luck!
I dont believe the train run as much after a certain time at night because the train to the car rental doesnt run as much as during the day. However, I don't think you will have to wait that long and the ride to the parking garage is fairly short.
