One of the illustrations shows the brake as appliedto a maximum traction truck; in this case but one shoe is usedbetween each pair of wheels. In the ordinary bogie truck, whereboth wheels have a separate brake shoe, two track shoes are alsoused, as shown by the detail electrically connected to their respective contact pins by means ofthe enclosed cord, and cylindrical terminals on the end of theflexible cord connecting with the car make the circuit completebetween the telephone and the overhead telephone wires. Eachtelephone is furnished with a holder, which is placed in the car inany convenient place.
