The Civil Engineering Department has as its responsibilities the proper design, construction, maintenance and renewal of all track, bridges, culverts, viaducts, buildings, roads, platforms, drains, fences and water supplies. The department is also responsible for the maintenance of all engineering department transport vehicles, tools and plant. However, the primary duty of the department is the track and its supporting structures (bridges, culverts, etc.) These and other works must be inspected as frequently as possible in order to ensure that they are safely and efficiently maintained. Proper track inspection is the most important service the department can provide to ensure the safe passage of trains. The track inspector is the final link in a chain, which reaches from construction and maintenance to actual train operations.
