Toll Royal Railways have been busy refurbishing the Cambodian
rail system for the last few years.
Some old trains they have restored are on display at the Phnom Penh railway station, including this 1969 German diesel railcar and coach. Apparently there were two of these at one stage, but the other one is lying down an embankment in Battambang, after being blown up during the wars. As you can see from the pictures, it's the same model (perhaps the same train) as the one in this 1975 photograph of the Democratic Kampuchea leadership. Pol Pot is sitting in front on the left, with Nuon Chea behind. On the right are Vorn Vet and Ta Mok. At the bottom you can see the train as it was prior to restoration.
