If you look closely at this engine you will see that there is another type of engine used in our country which is somewhat similar to this. That is the M4 class Canadian ALCO engine that I described in a previous article. It has some similarities in shape as well as some technicalities. This is because the engine was manufactured by Indian DLW based on an original design by ALCO. The power supply engine here is completely ALCO 251B modeled.
Although not specific, I have heard that the reasons for producing these engines are as follows.
Once ALCO placed an order for a large number of locomotives for India, ALCO failed to supply such a large number to India quickly. As a solution, the Indians demanded permission to manufacture the engines in their own country. After obtaining the permission and technology, India produced the required number of engines by DLW in 1964, according to the original design of the ALCO. Now these engines are manufactured and exported to other countries. It uses about 2700 engines worldwide and has more than 1000 engines in India.Two such engines were first brought to Sri Lanka around 1996. Later 6 more engines were brought in and added to the drive under the M8 race class.These heavy-duty locomotives were the longest and most powerful locomotives in the country at the time and were often used for express trains as well as 15-18 compartment trains (some time ago used for office trains such as Samudra Devi and Mahawa. S10 trains are used for this engine which is capable of towing up to 20 compartments at a time)These engines are mostly used for North and East roads and coastal roads. This engine, similar to the M4, does not run on the Kandyan route (due to sharp bends), the Kelani Valley Road and the Matale route (only light trains run here) due to problems with the body length and bogie length. However, it is possible to drive on the Kandyan road to Kandy and beyond the Peradeniya junction to Nawalapitiya if required. There is almost no traffic on the Puttalam road either.In 2001, two more engines of this type were imported, which were smaller and less powerful than the original ones. It is said that the original engine of ALCO was slightly modified and designed with a 12 cylinder engine which was specially made for Sri Lanka. These have been added to the race in this country under the M8A race class.It is said that most of the parts are made of recycled iron. (It is now well known that India buys scrap metal from countries including Sri Lanka). There is an opinion that the reason for the rapid corrosion of these engines is due to the use of recycled iron. You have seen that almost all engines of this type in Sri Lanka are facing this threat. This situation is more common for engines running on the coastal road.
When these engines were brought to Sri Lanka, they originally had the Cow Catcher with straps commonly found on Indian trains. However, they were considered unsuitable for the country and a new Cow catcher was manufactured and installed locally. All the engines that were imported later were fitted with the right kind of cow catchers. Also, there was only one head light imported at this time. Therefore, double engines (Double head lights) were installed in all engines in this country. Also, when repairing this, the engine casing had to be lifted up and removed as it was before, and the casing of all the engines had to be rearranged so that it could be opened from the side as it was troublesome.
