Matale railway line terminus engineering: manual stub switches and semaphore interlocking?

The Matale branch line—extending 17 miles north from Kandy through Peradeniya—terminates at a single-platform station governed by colonial-era mechanical signaling. Station control relies on a mechanical lever frame interlocked with Tyer’s electric token instruments. To prevent conflicting train movements, signals cannot be pulled to "Off" unless the station master physically inserts the correct track token into the interlocking box. Stub switches and point levers in the yard are manually operated by pointsmen using weighted ground levers.
