We need the TPC on track 3.  We need the TPC in front of the TIU so that if
someone hits the halt button on a cab-1, the power will be cut to the TIU.
Without the TPC, there is no way for the cab-1 user to kill track 2 in an
emergency.  We felt it was a good idea to keep the TPC even if it is only
for this purpose...
