TRAiX K(iUllPED WITH ELECTRO-PNEUMATIC CONTROL SYSTEM chased about 150 equipments of the same type, which have beenin satisfactory operation for nearly a year. The Westinghouse multiple train control system was de-scribed in these columns two years ago, but a number ofchanges have been made in it, so that the present system is dif-ferent than that previously described. As will be rememberedthe Westinghouse system involves the use of compressedair for moving the current-controlling apparatus, electro-magnetic valves governing the admission of air to the con-trolling cylinders and low-voltageelectric circuits running from carto car for controlling the action ofthe magnet valves. The connec-tions for the low-voltage circuitsare the. only ones which have to RELEASE MAGNET,OPERATING MAGNET
