Co-Co Diesel Electric
These 5 standard gauge locomotives were built by CSR Qishuyan Locomotive Co. Ltd. in 2002 and are that companies model JMD 1360. Interestingly the company identifies the locomotives as 1000 mm gauge on it's website and one source also states that they are metre gauge, but another source lists them as standard gauge. Photos (including the one above) appear to show them on 1435 mm track as well. A change at the last minute?
They are standard gauge. They are numbered 2011 to 2015. One source classifies them as D14Er class but there are no photos of units marked that way.
They are regularly used on the Hanoi to Ha Long line.
Manufacturers data for this locomotive is as follows:
JMD1360 diesel locomotive is specifically developed and manufactured by CSR Qishuyan Locomotive Co., Ltd. for both passenger and freight transportation on Vietnam railways. The locomotive is equipped with 3508B diesel engine from Caterpillar, JF205F synchronous main alternator and ZQDR-410 traction motor; AC-DC electric transmission technology is utilized;The three-axle bogie is designed on DF8B bogie basis; and the car body is Jof outside corridor and load supporting platform.
Performance and characteristics: The locomotive adopts new technologies such as microcomputer control system, brake units and etc., with dynamic brake device having full-power self-load testing function.

Steam Locomotives generally used the traditional French classification system. A steam locomotive with a 2-8-2 wheel arrangement is classified as 141 class, a locomotive with 4-6-2 wheel arrangement is classified as 231 class etc. Pretty straight forward, except what they did if two classes had a 2-8-2 wheel arrangement I'm not sure. It didn't happen so wasn't a problem?
Diesel locomotives have a completely dfferent clasification system.
All diesel classes start with the letter 'D' (for diesel?) then a number which I believe is related to the locomotives power output. The third character defines Electric' (E) or hydraulic (H).
e.g. D5H class = Diesel + 500 hp + hydraulic.
Diesels used on the standard gauge (1435 mm) have the letter 'r' added to their classification. But the are cases where this doesn't happen.
Again, what happens if two classes are the same I don't know.
I am still investigating pre 1975 classifications. Some are the same e.g. 141 steam class, and some are different e.g. 'BB' class instead of D9E.
