The contactrails are rectangular in section and notched at the sides, so flammable. The whole tube also has been fitted with a sys-tem of electric lighting, electric lamps being placed at inter-vals of 40 ft., these lamps being supplied by an entirely differ-ent source of current from the cables which supply the powerfor operating the trains. The signalling system is that known as the Westinghouseelectro-pneumatic automatic, and is similar to that which isinstalled on the Metropolitan District Railway, which wasdescribed on page 417 of the Street Railway Journal forMarch 4, 1905.

The other running rail is divided^into blocksections by insulated joints and is connected to the negativemain through a resistance at one end of the section, and apressure of from 2 volts to 4 volts is maintained between thetwo running rails. Power is supplied from the motor genera-tor sets installed in each sub-station at 60 volts press
