The steady sticks would not serve as originallymounted owing to their lack of clearance. A longershank was, therefore, needed on the hanger to get suf-ficient distance between the messenger and trolley andto enable the steady stick to be mounted at an anglethat would give 8 in. clearance from the pantographhorn in a vertical plane. The steady stick bracketsare now made for horizontal as well as vertical swivel-ing of the stick, thus eliminating stick breakage. With 6600-volt operation the cars coasted withlowered pantograph over the crossings with 600-volt.
