From 1898 onwards, both the Selangor Government Railway and the Perak Government Railway in Malaysia received 13 and eight ten-wheelers respectively, which were built by various British manufacturers and hardly differed from each other. When the Federated Malay States Railways was founded, these became class G and were supplemented by eleven others. Two more came from the Malacca Railway, which only later joined the FMSR.
All but two locomotives were retired before World War II. These two were likely used by the British troops to form an armored train during the war. One of these is also said to have been brought to Siam and Burma by the Japanese.
