ආයුබෝවන්.අපි පසුගිය සතියේ Life On Rails යූ ටියුබ් නාලිකාවේ එම් පන්තිය අවසන් කළා. බොහෝ දෙනාගේ ඉල්ලීම පරිදි මෙවර අපි තීරණය කළේ W පන්තියේ දුම්රිය එන්ජින් තුන පිළිබඳ වීඩියෝවක් ගෙන ඒමටයි.
Hello.We finished the Class M category last week on the Life On Rails KZitem Channel. At the request of most people this time we decided to bring a video about the three class W locomotives.

Everything in the video about the Class W1 engine has been translated into English. I think it is better than our foreign subscribers.

In shape, this W1 engine bears a close resemblance to another engine you have always seen. That's the M6 racing class engine. Both the M6 and W1 engines are manufactured by the same manufacturer. Although similar in shape, the two engines differ greatly in their characteristics. The manufacturer of the W1 engine is said to have used the DHG-1200, one of the most successful designs for locomotives. However, THYSSEN HENSCHEL (West Germany), the manufacturer of these engines, split into different parts some time ago and each of those parts came under different companies. One company was ADtranz, which later became Bombardier, and they still make trains today. Another part of the original THYSSEN HENSCHEL became Henschel Antriebstechnik, and today they only manufacture gearboxes and some train parts.
However, this W1 class locomotive is also unique in our field of railways due to the fact that the manufacturer is also here. It is considered to be the "first diesel hydraulic type locomotive" brought to Sri Lanka for transportation on a railway line (see this article on Diesel Hydraulic Technology). By this time the S2, S3 and S4 power trains were running on hydraulic technology. But when it comes to locomotives, the W1 is considered to be the first diesel hydraulic locomotive to be imported for board gauge.
Also, the total number of locomotives of this type brought to Sri Lanka in 1969, the year when the largest number of locomotives were imported, was 45. It is a very large number and the W1 class engines are the most imported type of engine in the country. When these were brought to Sri Lanka, only the M1 and M2 class locomotives ran as other major diesel engines. Most other trains were powered by steam engines. Accordingly, with the advent of these W1 engines, many of the steam powered engines that had been in use until then were taken out of service. These W1 engines were used for most trains powered by the same steam engines. For about 25 years from the time of its introduction until 1995, this type of engine was sometimes used in addition to the M-class engines for most mountain trains, including the Kandyan and Podi Menike trains. These engines were able to run on any road in Sri Lanka except the Kelani Valley Road which was a narrow gauge road until about 1996. At present these engines can run on any railway line in Sri Lanka. It is said that they had a very smooth ride like a car and drove with very little noise and as a result their drivers had a very pleasant attitude towards these locomotives.
However, about 20 years after its inception, the unfortunate season of these engines began to deteriorate. The manufacturer recommended that new engines be fitted to these engines at the end of the 10-year warranty period. Accordingly, the relevant maintenance should have been done around 1980 but it was not done. Installing a new power supply engine for a train engine is an extremely complex and costly task. Therefore, it is possible to purchase new locomotives if required with the money required to install new power supply engines for these engines. However, this may have been due to the lack of funds for the railway service to be used for the purpose.
These short-range engines had a very high RPM of 1500 RPM, and their power supply engines weighed quickly due to the acceleration and deceleration that occur at short distances. It was also started because the recommended maintenance work was not done properly. It was unfortunate that many of these had to be taken out of service by the 1990s due to their dilapidation.
