The heav-iest gradients are 7 per 1000 (1 in 143), without counting asmall length on the north side where the gradientis 10 per 1000. The sharpest curve on the main line is300 metres (984 ft.) in radius, and 150 metres (492 ft.) isthe minimum used on the siding. The conditions the build-ers had to meet involved the hauling of one locomotive ofa passenger train weighing 300 tons at a speed of 70 kilo-metres (43.5 miles) per hour, and the same engine was alsoto be capable of hauling 400-ton freight trains at about 35kilometres (21.7 miles) per hour.
