Hua Hin Railway Station is one of oldest train stations in Thailand with a unique architecture. Its most striking feature is the royal waiting room constructed in the jaturamuk (จตุรมุข) style, an architectural style in which a building has four gable ends or four entrances, sometimes with each one pointed to a direction of the compass. Originally, during the reign of King Wachirawut (วชิราวุธ), i.e. Rama VI, it was part of the Sanam Chan (สนามจันทร์) Palace in Nakhon Pathom (นครปฐม) province, a 888 rai domain of buildings in built in 1907 by Wachirawut (Vajiravudh) when he was Crown Prince. In 1968, the waiting room, then called Sanam Chandra Palace Railway Pavilion to Hua Hin to become the royal waiting room at the local train station and was renamed Phra Mongkut Klao (พระมงกุฎเกล้า) Pavilion, after another name used for King Rama VI. The original station building was built in 1910 and opened service in November 1911 with the third phase of the Southern Line between Cha-am (ชะอำ) and Hua Hin, which in January 1914 was extended further southward to Wang Phong (วังก์พง). In 1926, the Hua Hin train station was rebuilt by Prince Burachat Chaiyakon (บุรฉัตรไชยากร) to the current Victorian building still in use. However, construction of a new elevated dual track railway and associated station is currently in progress and can be seen on the background in this video.
