I was in Badulla that day.. The SPL derailed near Kotagala I think, M6 797 was the 1046 pilot engine and the main was 785. Somehow 797 took the set back to Colombo and 796 was attached as the 1045 pilot engine with 788. 797 was supposed to haul the 1126 but that was worked by the previous day 1596 engine, M6 790. The previous day 1007 engine, M6 795 only worked the 1008, which I came back in.
M5c class locomotives probably best and most attractive train engine brougjt from japanese firm in 1979 with maximum horse power 1800-2000 aswellas maximum speef around 97 kph. Which also has minimum wheight around 84 tons aswell.M5 catogery locomotives minimum length exactly around 55 feets. This class of locomotives mostly used on up and hillcountry railway tract because M5c enginrs have dynamic and airtight break systems aswellas most trusted and garanteed train engines inbadulla and kandy matale railway lines aswell.
