Shin-Karikachi Signal Base, Railway signal base in Shintoku, Japan

Shin-Karikachi Signal Base is a railway signal facility in Shintoku, on the island of Hokkaido, Japan, with two tracks where track 1 serves trains heading downhill and track 2 handles uphill traffic. The facility is linked to the adjacent rail line through a long tunnel running across a steep section of the route.

The base opened on September 30, 1966, as part of the railway infrastructure built to connect the Ishikari and Tokachi regions of Hokkaido. It operated for nearly 60 years before the relevant section of the Nemuro Main Line was closed in 2024.

The name of this signal base combines "Shin", meaning new, with "Karikachi", a word that references the meeting point of two old regions: Ishikari and Tokachi. Standing at the facility today, you can sense this boundary role in the way the tracks split traffic going in opposite directions across the pass.

The facility is not open to the general public and is intended for railway staff only. Anyone interested in viewing the area from nearby should check local rail connections in advance, as services in this part of Hokkaido are limited.

Even after the line closure in 2024, the base kept its status as an active facility rather than being formally decommissioned. This makes it a rare case where a railway point remains officially operational without running any regular passenger service.
