The Aberfeldy Branch of the Highland Railway: the Tummel Viaduct at Logierait, [Scottish Highlands], 1865. 'A short branch of the Inverness and Perth Junction Railway has lately been constructed to Aberfeldy, in the upper valley of the Tay...Though its length is less than nine miles, its construction has been a task of some difficulty, and does much credit to the engineers, Messrs. Joseph Mitchell and M. Paterson, and to Messrs. Macdonald and Grieve, the contractors; the earthworks extending to about half a million cubic yards of cutting, and an equal amount of embankment; while the bridges, including the viaduct across the Tummel and the Tay, are no less than forty-five in number...This Aberfeldy branch crosses first the Tummel and then the Tay within about half a mile of the village of Logierait...The Tummel viaduct consists of two main openings 122ft. span each, and two side girders of 35 ft. span each, making the entire clear waterway 314 ft. The girders are elevated 16 ft. above the bed of the river, and are supported by six cast-iron cylinders, 8 ft. diameter. These cylinders were sunk into the bed of the river 22 ft. on the average, by the aid of divers...The total height of the cylinders, with the ornamental towers, is about 55 ft.'.
