Composing each set of crossingsthere were sixteen frogs, four special, open hearth, cast-steel, double switches and mates, four single switches andmates, four 90-deg. angle crossings and six 38-deg. anglecrossings. All were made from 9-in. Cambria guard railof weight 104 lbs. and 107 lbs. per yard.
