Abstract
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.
