The Magic Behind Our Steam Trains
Magic Kingdom
The Magic Behind Our Steam Trains, a Magic Kingdom park tour, explores Walt Disney's passion for steam trains, while giving Guests the opportunity to join the opening crew as they prepare for the daily railroad operation at the MAGIC KINGDOM. This tour also offers the rare opportunity to visit our backstage "roundhouse".
The tour highlight is the train trip back to the roundhouse with an up-close and personal look at one or more of our locomotives, but the experience is also rich in history about Walt Disney's lifelong fascination with steam trains, how we acquired our four old locomotives, and the operating procedures we follow to serve our annual ridership of over 3 million. You will received an exclusive pin, designed by one of the engineers, at the end of the tour.
Offered Monday, Tuesday, Thursday and Saturdays at the MK turnstiles at 7:30 am and ends approximately 10:30 am.
The cost is $40 plus tax and theme park admission is required. Guests must be at least 10 years old to participate. DVC members can receive a 15% discount.
