Chumphon railway station is a railway station in Tha Taphao Subdistrict, Chumphon City, and is the main railway station for Chumphon Province. It is a class 1 railway station, 468.534 km (291.1 mi) from Thon Buri railway station. It is the first fueling station from Bangkok, and thus all trains going further south must stop here. Chumphon is also the site of a locomotive depot.

On the site, there are two decommissioned locomotives:

• 178 Unit No. 21810 (North British Locomotive Company)
• 235 Unit No. 59441 (Baldwin Locomotive Works)

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). In 1922, night services became available.

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. The line was built in December 1943. In March 1945, Allied bombings (using Consolidated B-24 Liberators) destroyed Chumphon station and the line to Khao Fachi. After the war, the Japanese requested the dismantling of the railway to prevent further Allied attacks on Japanese military bases.

Chumphon Station was rebuilt in 1948. It is currently being a rebuilt again as part of the double tracking project
