It takes 20-30min, and one of the coach cars are really cool in side. And yes it's 10 bucks and they take card, the train it self is where you get the tickets, goes to oaks park and you may get off and enjoy a afternoon there and return on the train back to the museum which is located near omsi. By the way again the train tickets are purchased at the train, not the museum.
They don't offer rides. Its a museum.
$10 to ride on a vintage diesel train to Oaks amusement park and back.
