Members of the Trinity College Automotive Society, together with Design and Motor Mechanism students at the Ordinary Level and Technology students at the Advanced Level, visited the sub-department of the Chief Mechanical Engineer’s Workshop (Ratmalana) of Sri Lankan Railways on an educational tour organised by the College. The group was accompanied by Mr Subash Dhanasekara and Mr Chathura Subhawickrama.
The visit offered a clear look at how train engines are assembled, repaired and maintained, as well as the processes involved in restoring different engine classes, including the M and S classes. The group explored a series of workspaces, among them Workshops 14, 21, 22, 23, 24, 27 and 28, along with the Lathe and Foundry Workshops and the Electrical Workshop. These visits helped broaden their understanding of mechanical engineering and industrial practice.
During the tour, the group examined key differences between two-stroke and four-stroke engines, watched injector cleaning and maintenance, and observed cooling systems that use liquid and air. They also watched overhauling procedures, studied air and vacuum brake systems, and saw motor winding and repairs carried out on both AC and DC motors. Time spent in the Foundry provided insight into mould casting with cast iron, aluminium and other alloys.
The Trinity College Automotive Society records its appreciation to the Department of Railways and the Chief Mechanical Engineer for granting access to the facility. The guidance offered by engineers, foremen, supervisors and staff enriched the learning experience. The Society hopes to arrange another visit in the coming year.
