Gravel is found in large quantities at several points along theline, and this is employed as ballast. Practically all thecurves are of sufficient radius to permit of full-speed opera-tion of cars around them, and the most excessive, grades areencountered at the approaches to the viaducts. The trolleysof No. 00 wire are supported 20 ft. above the rail. Quite anunusual feature in connection with the line will be the ar-.
