Mallet locomotives

A batch of 0-6-6-0 locomotives were built by Baldwin c1918 for Russia but the order was cancelled following a change in the Russian Government. Two were purchased by FMSR in 1920 and used on the Port Swettenham - Kuala Lumpur line for slow, heavy freights. They survived only for about 8 years. They had single axle plus 4-wheel bogie tenders.
