Khun Tan Tunnel is the longest rail tunnel in Thailand that is 1,352 metres long. It was built by a German named Mr. Emile Eisenhofer, but it was not finished because during the construction of the tunnel there was World War I. This caused Emile to return to his country. Then, in 1918, Krom Phra Kamphaeng Phet Akarayothin, Father of the Thai Railroad came to be a construction worker. The Tunnel was completed in 1918.
