Abstract
A railroad switch mechanism wherein the switch points of a track switch are moved between normal and release positions by a switch machine connected to the switch points by throw rod, lock rod and detector rod assemblies which are adjusted to have predetermined lengths. The lock or detector rod assemblies have couplings which enable temporary disconnection from the switch points when testing to verify whether the operation of the switch to normal and reverse positions is within an allowable range of variations with respect to the stock rails with which the track switch is associated without affecting the adjustment of the length of the assemblies and requiring long and costly readjustment after the completion of testing.
