SWITCH DEVICES SELECTIVELY OPERATED IN CORRESPONDENCE TO THE OPERATION OF THE BRAKE VALVE ON THE LEAD LOCOMOTIVE ESTABLISH SUITABLE CONTROL CIRCUITRY FOR RADIO TRANSMISSION OF APPROPRIATE BRAKE CONTROL SIGNALS FROM THE LEAD TO THE SLAVE LOCOMOTIVE. ONE OF THE SWITCHES IS CONTROLLED THROUGH AN INTERMEDIATE VALVE MEANS SO AS TO CAUSE REDUCTION OF EQUALIZING RESERVOIR PRESSURE ON THE SLEEVE LOCOMOTIVE IN CORRESPONDENCE WITH THAT ON THE LEAD LOCOMOTIVE THEREBY INITIATING A SERVICE APPLICATION OF THE BRAKE ON THE TRAIN AS THE SLAVE LOCOMOTIVE CONCURRENTLY WITH THAT INITIATED AT THE LEAD LOCOMOTIVE.
