Abstract: A contact shoe assembly for a train movable along a support track having an electrically-energized power rail extending substantially parallel with the support track. The contact shoe assembly includes a support member with two spaced-apart guide channels. A bracket arm is positioned between the guide channels and equipped with ball bearings that roll within the guide channels. A contact shoe is connected to a lower outwardly-extending portion of the bracket arm for contacting the power rail. A spring mounted between the support member and the bracket arm biases the contact shoe into a yielding engagement with the power rail. Vertical movement of the bracket arm responsive to a varying height of the power rail maintains the contact surface of the contact shoe horizontal and parallel to the power rail. This parallel arrangement reduces wear to the equipment and ensures the effective transmission of power to the train.
