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.

Railroad virtual track block system

A railroad crossing warning circuit includes a lamp and a signal generator for generating a first signal of a selected frequency. Divider circuitry divides the frequency of the signal to generate second signal at a flashing frequency. A switch responsive to the second signal controls current flow through the lamp and cause the lamp to flash at the flashing frequency.

Systems and methods for controlling railroad highway crossing flashers

A system for remotely monitoring compliance with a railroad signal associated with a section of railroad track includes a remote aspect compliance subsystem for monitoring compliance with an indication for the section of railroad track represented by an aspect of the railroad signal. The remote aspect compliance subsystem selectively generates corresponding compliance messages, which are communicated via a network to server for display and processing.
