The gage of the track is 3 ft. 6 ins.,laid with girder rails, weighing 83 lbs. to the yard. Thefish-plates are of steel, 2 ft. long, and weighing 50 lbs. per pair, embodying the method of fish-plate constructionknown as the Dicker patent joint. The rails are bondedwith double Neptune bonds, no cross bonding being used.All the special track work, consisting of junctions, etc.,was manufactured by Dick, Kerr & Co. at their works atKilmarnock, Scotland.

The usualfeeder pillars are arranged at half-mile intervals, eachterminus being in telephonic communication with thepower station.
