The control used is Sprague-General Electric MultipleUnit Control for alternating and direct current operation. Thiscontrol is similar to the type M control for direct current oper-ation, the essential difference being the addition of the and connections and the necessary appliances forchanging from the one current to the other without interferingwith the motion of the car. There is the usual master controllerthe train line, the direct current resistance grids and the con-tractors. The master controller used is of the same shape andappearance as the ordinarjr city car controllerj hut it is smallerand is provided with a dead man release. While this controllertakes its current from the trolley it is so built that no heavycurrents are allowed to pass it and it is protected by fuses* The contractors are
