The Colombo Suburban Railway Project, CSRP, which is funded by Asian Development Bank, is aiming at electrification of the section from Veyangoda to Panadura (64 km) in the Colombo Suburban Area of Sri Lanka. This is a 600 Million USD project, under which the Railway-Tracks will be rehabilitated and reconstructed to increase the speed from 80 to 100 kmph, the Signalling and Telecommunication System in the section revamped, the Railway Stations upgraded, Multi-Modal Centers erected and finally electrification carried out.
Whereas Part I deals with the technologies and the difficulties of re-CSRP, PART II, PDFengineering the existing tracks to become sound, healthy and fit to cater a modern high capacity Urban and Suburban Rail Transport System, Part II deals with technical solutions for the KV-Line and the Main-Line from Colombo to Kandy, especially for the Balana Incline between Rambukkana and Katuganawa, that can be learned from other advanced railways.
In order to increase the geometry stability in the tight curvatures with troublesome and narrow top-formation of the KV-Line and the Balana Incline, the author suggest making use of Thyssen/Krupp Schulte GmbH Y-SHAPED STEEL-SLEEPERS with Pandrol Fast Clip rail-fastenings and long welded rails. This track system is used in Italy, Switzerland and Germany for mountain and hill railways with tight curves and steep ruling gradients. Y steel-sleepers are advantageous on shallow ballast beds and narrow top-of-formation width and allow long-welded rails in tight curves. In curves, those sleepers provide the rail-grid with excellent geometry stability.
A conversion of the KV rail-track to METER GAUGE would provide many advantages, especially higher speed in tight curvatures on narrow formation. METRE GAUGE CONVERSION should be possible, since the KV ends at Maradana/Fort and carries no long-distance trains proceeding on other broad-gauge lines.
As ROLLING STOCKS the author suggests to make use of modern Light Weight Rail Cars of Swiss Stadler technology propelled by Diesel-electric power packs rating 2 x 800 KW in a middle traction van/module with a free gangway for the commuters, as the author has designed and envisaged for the LANKA ECONO RAIL PROJECT, initiated by L. Perera of Micro Cars. Those Rail-Cars with middle traction run in Lithuania, Germany, Switzerland, Italy and Greece.
