The joint fastenings on street railway track have been patternedsomewhat after those in use on steam railroads, so that the fail-ures on the latter will assist in finding a remedy for street railwayjoint troubles. When the old-fashioned chair joints were aban-doned and fish plates (two straps of iron) were adopted, achange for the better as regards vertical strength, was secured,though all support of the base of the rails was sacrificed, beingdependent on the bearing or support these straps gave at the pointof contact under the head of the rail, assisted somewhat by a one-tie support at the rail ends. As creeping of track had to be pre-vented without slot-ting the base of therails, suspended jointscame into use with aflange to the fishplates at their base,extending beyond andl
