Such a project changed the racing classes of the newly fitted M5 class engines to sub-racing classes such as M5A, M5B, M5C as the project is entirely a Sri Lankan project. But because the W3 project was a contractual agreement with a foreign company, the final product was classified as a new race class, the W3. The company was ADtranz, which had previously bought Henschel, the maker of the W1 class engine. Under the agreement, 10 new sets of Caterpillar 3512 DI-TA engines were used for the project. United Tractors Ltd. acted as local agent for the project, which was fully implemented with the assistance of the Dutch Government.
Under this project, the original Power Plant and Power Transmission unit of the W1 engines used were removed and replaced with new ones, and the operation of the engines so fitted was a modern electronic control system outside the existing mechanical control system of the W1. Assigned to. Accordingly, most of the work on these new locomotives is controlled by the same electronic control system. According to the original design, the chimney was slightly smaller than that of the W1. It is mounted close to the windshield, but the rear window is slightly off at the driver's request due to the discolouration of the windshield by the exhaust gases. it was.
Trains that require high power during operation are equipped with the ability to use multiple units (or multiple locomotives attached to one side). The W3 locomotive is powered by a double-headed locomotive that controls both engines from the same cabin. The W3 engine also incorporates the Hydro Dynamic brake feature not found in the W1. These engines also feature air brake and vacuum brake, which is another advantage of being able to run even with Chinese cabs. The W3 engine is also the only hydraulic engine that can be used in Chinese cabins.
In terms of driving, these engines are generally lightweight and can run on any railway line in the country, including Kelani Valley and Matale. It is also often used for rail transport (sleeper transport, etc.).
The noise generated by the engine during the operation of these engines is slightly higher than that of the original W1 engines. It is also said that the lifespan of these W3 engines is coming to an end. The warranty period for these was 10 years from the date of repair. Therefore, by the year 2008, the relevant companies had recommended that these be referred for significant major repairs. However, 9 of these W3 engines are still running, and only the 636 engine has been removed from service due to the destruction of the power engine frame.
