On the site, there are two decommissioned locomotives: Chumphon was the location where the two sides of the Southern Line construction met, one from Thon Buri, one from U-Taphao Junction (Hat Yai).

This was completed on 17 September 1916, and services started running from Thon Buri to U-Taphao, stopping at Chumphon and Thung Song Junction for fueling and resting (at the time no services ran at night).

Chumphon was a water and wood refueling station for steam locomotives, as well as a place for reducing carriages going further south.

During the Second World War, Chumphon acted as a junction for the 90 km military line to Khao Fachi, Ranong, under the coordination of the Imperial Japanese Army.

In March 1945, Allied bombings (using Consolidated B-24 Liberators) destroyed Chumphon station and the line to Khao Fachi.
