Western River Railroad, Heritage railway attraction in Maihama, Japan

The Western River Railroad is a 762 mm narrow-gauge steam railway attraction at Tokyo Disneyland, departing from Adventureland station and returning there on a one-way loop through Critter Country and Westernland. Its four kerosene-fired 2-4-0 locomotives, built by Kyosan Kogyo, pull three open coaches each; the green No. 28 Missouri carries a gold "MISSOURI" plaque and "TOBY" nameplates.

The Western River Railroad opened with Tokyo Disneyland on April 15, 1983, initially with three locomotives: Missouri, Rio Grande and Colorado. A fourth, Mississippi, joined in October 1991 to increase capacity. Because Japanese rail regulations then treated any line with more than one stop as a railway business, the ride was built with a single station and a one-stop loop; that rule was abolished on April 1, 1987.

The trains follow design models from American Western cinema and give visitors an impression of historical steam locomotives. Along the route, travelers encounter moving figures that recreate scenes from frontier times.

Boarding and alighting take place at a single station in Adventureland; the line is a one-way loop and not a means of transport between park areas. The train passes two scenic stations without stopping: Stillwater Junction, visible on the right shortly after departure, and Dusty Bend Depot in Westernland. The ride runs at a maximum speed of 12 km/h and is suspended around the fireworks show.

The tracks pass through tunnels and over bridges, and travelers pass scenes that recreate the Colorado River and the wilderness of the American West Coast. During the ride, sounds of animals and waterfalls can be heard.
