Project Overview
Rehabilitation and drainage improvement of the railway line at Magamaga and Budumbuli was identified as a key project in improving the track availability which was affected by the speed restrictions and the occasional line blocks at these locations. Both these locations are within cut sections stretching from Mileage 312/4 to 312/8 at Magamaga, and Mileage 322/2 to 322/6 at Budumbuli.
Due to the proximity of human activity to the railway track especially at Budumbuli, catch water drains were blocked by waste resulting into surface runoff and attendant sedimentation being directed onto the railway track. Additionally, boulders on the steep back slopes became unstuck and were released onto the railway track during heavy rains. All this led to line blocks in order to clear the track of the debris or temporary speed restrictions (TSRs).
At Magamaga, all the surface run-off from the surrounding hills was directed onto the railway track due to inadequate and blocked catch water drains. This coupled with the shallow and blocked side drains within the cut section, led to water ponding on the railway track that caused train failures (wheel slip) and line blocks. Eventually, this water ponding led to an unstable track and speed restrictions due to a weak formation.
As such, this project was identified to rehabilitate the railway line through re-ballasting at these sections with contaminated or no ballast and poor track joints as well as improving the drainage at these locations through stone pitching of the side drains, opening the catch water drains and culvert construction.
Due to a limited available budget, a variation order was issued to extend the coverage of the drainage improvement (stone pitching) in lieu of the re-ballasting. The project would play a key role in improving track availability in line with its 5 year strategic plan as one of its strategic objectives.
