ALL LOGIC CIRCUITS ARE REDUNDANT. ALL INSTRUMENT CHANNELS, BISTABLES, ANNUNCIATORS, COMPUTER INPUTS, AND INDICATOR LAMPS ARE NOT REDUNDANT.
MANUAL CONTROL DO NOT HAVE REDUNDANT ACTUATORS, BUT DO HAVE REDUNDANT CONTACTS WHERE LOGIC IS REDUNDANT.
ALL INDICATOR LAMPS, COMPUTER INPUTS & ANNUNCIATORS ARE CONNECTED TO BOTH TRAINS SO THAT A SIGNAL IN EITHER TRAIN WILL ACTUATE.
