The Usui Pass line was historically the steepest section of the Japanese National Railways, requiring the use of rack-and-pinion trains until 1963.
The park houses the EF63 electric locomotive, specifically engineered to assist trains climbing the 66.7 per-thousand gradient of the Usui Pass.
Visitors can physically operate a retired locomotive in a simulator-style experience on-site.
The park's grounds include a preserved section of the original trackbed used by the Japanese Imperial Railway.
The location was once a major logistical hub where locomotives had to be coupled or uncoupled to traverse the incline.
Usui Pass Railway Heritage Park is an open-air museum located at the site of the former Yokokawa train station in Gunma Prefecture. It documents the history of the steep Usui Pass, once the steepest section of a major railway line in Japan. The facility showcases a vast collection of decommissioned locomotives, including electric and steam engines that navigated the incline. Visitors can operate a miniature steam train and ride a trolley on a portion of the original track. The museum features an extensive indoor exhibition hall displaying railway equipment, signaling tools, and historical photographs. It stands on the border of Gunma and Nagano prefectures, serving as a landmark for the transition between the Kanto and Chubu regions. The park preserves the infrastructure of the defunct Shin-Etsu Main Line segment.

Wear comfortable, closed-toe walking shoes to explore the extensive outdoor train displays.
Plan to participate in the 'Railway Experience' activities early in the day as slots can fill up quickly.
Bring a hat and sunscreen as the outdoor exhibition area offers minimal shade during summer months.
Do not expect to see the full original rail line still in operation; the main line through this pass was permanently closed in 1997.
Closed on Tuesdays; closed for several days during the year-end and New Year period.
Do not touch, climb on, or enter restricted areas of the stationary locomotives unless explicitly permitted by staff.
