Sri Lanka Railways S12 is a class of Diesel-electric multiple unit (DEMU) built for Sri Lanka Railways by China's CSR Corporation. The first batch arrived in Sri Lanka in August 2012. They were built to replace locomotive-hauled passenger trains. Seven of the S12 DMUs were ordered to strengthen long-distance travel on the Main line from Colombo to Badulla. Four of S12s were built to serve the Kelani Valley Line. The remaining set was designed as a luxury train.
