Kunming-Singapore Railway

The Kunming–Singapore railway, also referred to as the Pan-Asian Railway, is a network of railways that connects China, Singapore and all the countries of mainland Southeast Asia. The concept originated with the British and French colonial empires, which sought to link the railways they had built in southwest China, Indochina and Malaya, but international conflicts in the 20th century kept regional railways fragmented.
