Genebal Bemabks. The maximum gradient of the present line between Bonny Glen and Turakina is 1 in 50, but there are two or three sharp curves near Turakina which I understand cause considerable inconvenience to heavy traffic. I examined this portion of the line, and consider that, with a small amount of work, a great improvement could be effected, or, if thought desirable, the mile containing the l-in-50 gradient, and these sharp curves, could be reduced to 1 in 60 or 65 at a cost of about £3,500. In surveying these deviations I have endeavoured to keep as near to the existing line as possible, and, with the exception of Fordell, no station of any importance would be affected by the deviations. With regard to the curves throughout the length of deviations surveyed, they are generally easy, nothing sharper than 10 chains radii being introduced. The country generally is subject to land-slips, particularly in the vicinity of Fordell, but as a rule they are not deep, being the surface of from lft. to 3ft. in depth overlying the marine clays or papa rock. I have especially studied to keep clear of treacherous ground, and do not consider that any danger from this source need be apprehended. Traces of ballast appear along the route, but not in large quantities. It might, however, be plentiful although not showing on the surface. The total length of the deviations considered in the four sections between Turakina and Waitotara is practically 27f miles, giving an excess mileage of, say, 30 chains over the present line. These deviations would reduce all gradients steeper than 1 in 50 over the entire distance between Marton and Eltham (according to Public Works records of the line as constructed). The prices upon which these estimates are based are supplied by the Public Works Department, and the total cost of proposed deviations compiled from the estimates herein given is £271,130.
