Abt Road, Rail trail in Annaka, Japan

Abt Road is a rail trail in Annaka, Japan, that follows the old Usui Line. It runs from Yokokawa Station past the Maruyama substation and the Usui Third Bridge, known as Megane Bridge, to the former Kumanodaira signal station.

The trail follows the former Shinetsu Line, which closed in 1963. In 1996, work began to turn the abandoned track into a walking path, and by 2012 it reached the old Kumanodaira signal station.

Along the trail, you can see the old brick bridges and tunnels that are part of the Usui Pass railway heritage. Local people often walk here to enjoy the changing seasons, and the path offers a way to experience the region's railway past firsthand.

The trail starts near Yokokawa Station, where you can also find parking and facilities. The path has some steep sections and cracks in the pavement, so wear comfortable shoes and allow enough time to walk at an easy pace.

The trail is named after the Abt system, a special rack railway used to climb steep slopes. You can still see traces of this system in the old track beds and structures along the route.
