Abstract
A system for indicating occupancy of track sections in an interlocking area is disclosed comprising a multicomputer system which is assigned to several track circuits and processes the 'unoccupied' or 'occupied' indications of these track circuits. The multicomputer system, which is of a fail-safe design, also checks the operation of the associated track circuits and transfers an 'unoccupied' or 'occupied' indication of an associated track section to the interlocking station only if the test of this track circuit was positive. Any failures detected are also signaled to the interlocking station.
