Grand Canyon Railway, Heritage railway in Arizona, United States.

The Grand Canyon Railway is a historic rail line in Arizona that connects Williams to the South Rim of the Grand Canyon, covering 64 miles (103 kilometers) through high plateaus and pine forests. The trains run on a single track that winds through open landscapes and wooded sections before arriving at the station near the canyon.

The line opened in 1901 as part of the Santa Fe Railway network and greatly reduced travel time to the canyon compared to earlier stagecoach journeys. Operations ceased in 1968 due to increasing car traffic and resumed only in 1989 as interest in environmentally friendly alternatives grew.

The line's name comes from the canyon it serves, and the railway company shaped the South Rim's tourist village: it built the El Tovar Hotel, opened in January 1905 just 20 feet from the rim, and architect Mary Colter designed several of its buildings. The 1910 log depot at Grand Canyon Village, the last operating log head-end station in the United States, is protected as a federal landmark.

The ride takes about two and a half hours each way and allows several hours at the canyon before the train returns. Booking early usually makes it easier to find seats in the different carriage classes, which vary in comfort and viewing options.

Some rides are interrupted by performers dressed as bandits who ride horses alongside the train and stage a mock hold-up scene. This entertainment recalls Wild West myths and often delights children in particular.
