Abstract:
A railroad switching apparatus utilizing a tie which is positioned under rails and points used in switching railroad cars. A support is interposed the tie and the rails and points and includes a passageway to guide the first and second indicator bars which are attached to the points. A slider is also employed at the attachment point of the indicator bars to the points to accommodate the thermal expansion and contraction of the rails and points. The indicator bars are formed into a coaxial unit in order to allow simple observation of the relative movement between the first and second indicator bars to determine proper movement of the points relative to the rails.
