Abstract
A method of railroad track control includes partitioning a physical track block into a plurality of virtual track blocks, the physical track block defined by first and second insulated joints disposed at corresponding first and second ends of a length of railroad track. The presence of an electrical circuit discontinuity in one of the plurality of virtual track blocks; is detected and in response a corresponding virtual track block position code indicating the presence of the discontinuity in the one of the plurality of virtual track blocks is generated.
