1. An apparatus for testing a pneumatic system on a tracked vehicle, the apparatus comprising:

  • a. a signal producing means disposed on the track wayside in close proximity to the track;

    b. a first inductive device located on the vehicle for selective stationing adjacent said signal producing means so as to be magnetically coupled thereto when a signal is produced therein;

    c. a second inductive device located on the vehicle in spaced relationship to said first inductive device;

    d. coupling means located on the vehicle for electrically coupling said first and second inductive devices in response to the condition of a pneumatic system aboArd the vehicle; and

    e. a signal receiving means disposed on the track wayside in spaced relationship to said signal producing means, said signal receiving means being adjacent and magnetically coupled to said second inductive device when the vehicle is selectively stationed, so as to be responsive to said signal producing means through said coupling means.
