Abstract
287,475. Rangiertechnische Ges. March 21, 1927, [Convention date]. Track apparatus actuating signals other than on trains.-A relay, which controls safety devices, is connected to two or more insulated portions of track rail and picks up its armature only when both sections are connected by wheel axles to the opposite rail but holds its armature so long as one section is so connected. The relay may have two coils r<1>, r<2> each connected to one insulated section i<1>, i<2> or may have one coil connected to the sections through resistances in parallel.
