These railbuses are of Japanese origin. This first one used to be Japan's national railways JNR train RBE26007 of JNR's 300 series. Beginning from 2005, members of Japan Railways Group and other, privately owned Japanese railway companies donated a sizeable amount of old rolling stock to Myanmar Railways. The front of the train is still in the old colours of JNR.

Also this diesel locomotive DD930 is from Japan and it still carries the original JNR colours. It has only received a small Myanmar Railways MR logo on its front. This is a four axle dieselhydraulic locomotive built by Nippon Sharyo in 1961, fitted with a 1100 horsepower MAN engine built under license by Mitsubishi.

A similar formerly Japanese diesel DD.933 is leading a passenger train. In the Japanese JNR numbering system the first D stands for diesel, second D indicates that the machine has four axles, 93 is the series or class and the last digit is the number of the locomotive.

Myanmar Railways diesel locomotive DF.2083. These machines are brand new. They were built by the CRRC Dalian Locomotive & Rolling Stock plant in China and they are of their type CKD7B. These are metre gauge locomotives specially designed to cope with very poor rail conditions, steep hills and high temperatures. Myanmar Railways got two batches of them in 2008 and seven of them in 2015. By 2018 Myanmar had already over 50 of these Dalian's Chinese machines. They are made for metre gauge, have three two-axle bogies and Caterpillar CAT3516B engines. Top speed is 100 km/h.

Two trains meeting, both with new Chinese type CKD7B locomotives. However similar, note how these two locomotives have slight differences in their front parts. The 2063 is a couple of years older. The very newest of these locomotives are all over dark blue.

Myanmar Railways MR locomotives of the class DF.1200 are actually designed and built in Myanmar, by the Insein workshop of the railways. They have a long tradition in repairing locomotives and coaches since 1870. The Insein Locomotive Workshop constructed this 1200 horsepower diesel locomotive and built the first one, DF.1200-01 in April 2007. This one, number 08 is the last one in the series and it was delivered in June 2010. The machines have Caterpillar's CAT 3508 B engines. It's easy to see that the basic design of this locomotive and the new Chinese CKD7B locomotives pictured above are closely related. But the basic design with the upwards tilted front screen and the 3x2axle bogies comes from France, from GEC Alsthom. They delivered to what then was Burma locomotives numbered DF.1601-DF.1645. They were put in service in 1971.

A closer look at the MR class DF.1200 locomotive. For being less than eight years old, the machine looks already now fairly worn and rusty. And when compared with the new Chinese locomotives shown above, it's clear that the basic design has been copied from China.

This diesel locomotive is a former Indian railways no.6123. It is a metre gauge machine made by the American Locomotive Company ALCo in the 1940s. In India it belonged to the locomotive class YDM-4 and worked on the Siliguri to Lataguri railway SGUJ. It was exported to Myanmar in 2010 as a form of neighbour help and in Myanmar it was renumbered to DF.1340.

The locomotives no. DF.1625 to DF.1645 were built by GEC Alsthom in France and put into service in May 1979. The locomotive weighs 73 tons, has an axle load of 11,95 tons per axle. This is Alsthom's type 1600 HP DEL V16BZSHR, with 6 axles. It has been retrofitted with a new Caterpillar CAT3512 engine in February 1995.

Myanmar Railways rail truck / rail tractor ED/RGC.122. Unfortunately it has not been possible to find any information about the origin or technical details of this one, but very similar rail trucks of Chinese origin are used for example in Africa.
