Disneyland fans have been waiting months to hear the memorable sound of the horn honking as the Disneyland Monorail glides above and throughout the resort. The “highway in the sky” has returned for guests to board once again as a part of the phased reopening of the Disneyland Resort.

The Disneyland Monorail has been a beloved attraction for decades, ever since it first debuted at Disneyland in 1959, becoming the first daily operating monorail in the Western Hemisphere. Originally known as the Disneyland- Alweg Monorail System, Alweg — a German transportation company — aided in its design. The monorail first glided on its beam around Tomorrowland, but was soon extended when new train models debuted and began transporting guests to and from Disneyland Hotel in 1961. At that time, it was the first monorail in the country to cross a public street, and it became more of a transportation system than a theme park ride. Disneyland Monorail later debuted trains with seating facing toward the windows in 2008.

Since its debut, the Disneyland Monorail has been powered by electricity, emitting zero direct emissions. In the 1970s, Disney started a Community Transportation division to market the clean-running and dependable monorails and people-movers to cities, but the only installation was a people-mover at the Houston Intercontinental Airport. Later, the technology was licensed to Bombardier, Inc.

The Disneyland Monorail not only serves as a fun transportation experience, but also offers a unique way to see the sights around the resort, including aerial views of Tomorrowland and Fantasyland in Disneyland park and Buena Vista Street in Disney California Adventure park.
