The head of the SRT governor’s office, Ekarat Sri-arayanpong, stated that the new track will enhance logistical operations along the 421-km route.
The upgrade is set to reduce journey times on the southern line by up to 90 minutes, making rail travel more attractive to tourists.
With trains no longer needing to wait for each other to pass, the system’s overall safety will also see significant improvements.
The railway begins in Nakhon Pathom and travels through Ratchaburi, Phetchaburi, and Prachuap Khiri Khan before concluding in Chumphon. Predominantly at ground level, the tracks are elevated in urban areas to alleviate traffic congestion.
Two major landmarks are located along the line. The first is the bridge across the Mae Klong River in Ratchaburi, which the government aims to develop as a new tourist attraction for the province, and the second is the new Hua Hin Railway Station, which maintains the architectural style of the old station.
Plans are underway for further dual-track expansions, including routes from Khon-Kaen to Nong Khai and Nakhon Ratchasima to Ubon Ratchathani in the northeast; Pak Nam Pho to Den Chai and Den Chai to Chiang Mai in the north; and Hat Yai to Padang Besar, Surat Thani to Songkhla, and Chumphon to Surat Thani in the south.
By the time these upgrades are completed in 2029, Thailand will boast 2,370 kilometers of dual-track railways. This extensive network is expected to significantly boost the nation’s logistic efficiency and tourist appeal, said Ekarat.
