Excerpt from Lectures, Light and Temporary Railways, and Temporary Expedients in Engineering Construction, Delivered at the School of Military Engineering, Chatham

The sleepers are spaced generally to the mile, and are sometimes half-round, 6' 6 long x 9 x in other cases 7' x 6 x 5 rectangular. Those for India are of Baltic timber, creosoted under pressure; in Brazil, and in Canada native timber is used. In India the half-round sleepers are laid round side down.

Mr. Wood of Middlesborough has introduced a form of wrought iron sleeper, which is specially adapted for light railways, is very portable, and, at present prices, as cheap as wood. Of this a model is exhibited.

The chief difficulty with this light permanent way is to keep the gauge.
