Each car is fitted with acomplete telephone set, thus enabling the crew to reportpromptly to headquarters any serious breakdown or thefailure of any part of the system. Giant strain insulators are used on the span wires. They are located 6 ins. outside of the rail, between the trolleyhangers and the transmission line. The requirements ofthis service led to the development of a special mechanicalclip and soldered ear,to carrythe grooved trolleywire. Theclip is about 15 ins. long, with a smooth finished channel,on each side of which is a downwardly projecting lip,having on the inside a small rib, which fits into the grooveof the trolley wire. The latter is sprung into the channeland the sides of the clip are then crimped together, so thatthe ribs on the inside are closely fitted into the groove ofthe trolley wire. This would generally be considered suf-ficient to hold the
