All longitudinal and vertical joints in the conduitare sealed with bitumen to prevent the entrance of any stud is electrically connected with the cable, when the carpasses over it, by means of a plunger which is held by a springnormally away from the iron cable. When the magnets onthe car pass over the stud plate, the plunger is magnetically. [ ; ,^. yja G m
