The first railway in Thailand was a private line connecting Bangkok with Paknam at the mouth of the Chao Phraya River, a distance of 21 kms. Paknam at the time was the anchorage for sea-going ships that could not reach Bangkok. Work on the line was begun in 1887 and it was opened to traffic by the king on 11 April 1893. Besides the two terminals in Bangkok and Paknam it had ten intermediate stations.
