A system and method for virtual block operational status control with long block time delay is presented. The present disclosure can advantageously increase the capacity and safety of the existing railroad track infrastructure used by the railroads by determining whether a virtual block is healthy or unhealthy. The long block mode can provide a coarse granularity on the presence of a train. In virtual block mode, the system can implement a finer granularity so the virtual aspects of the sub blocks can be realized. The present disclosure provides a long block mode that can provide the system an opportunity to analyze the potential tradeoffs between granularity and reliability by determining which mode (virtual block or long block) is best utilized in a given situation. The system can operate by default in long block mode and ignore the virtual block capabilities until absolutely needed.

A railroad infrastructure communication network is presented. The network can include a plurality of infrastructure nodes distributed proximate a railroad track, such as near railroad equipment and/or assets. Infrastructure nodes can be configured to receive data from equipment sensor and/or assets and transmit such data via the network. Infrastructure nodes can further generate alert and/or alert packets based on such received data. Infrastructure nodes can self-define in a network infrastructure depending on configured connection types, and can for example, serve as repeater nodes (to promulgate a transmission to additional infrastructure nodes) and/or collector nodes (to collect data for a centralized server node). A server node can be configured to receive data and/or packet from infrastructure nodes and generate requests for additional systems, personnel, etc. to address such requests. The network can limit the data transmission size and leverage distributed processing capabilities to enable transmissions over long ranges, such as by reducing the bandwidth required to transmit packets.

A system and method for virtual block stick circuits is presented. The present disclosure implements specialized algorithms adapted to determine the true status of a virtual block based on multiple inputs from different perspectives. In one embodiment, the system can use the far house perspective of that virtual track segment and the PTC hazard for the near virtual track segment directly adjacent to the near house uses the near house perspective of that virtual track segment. For the middle virtual track segments, the near house perspectives of the middle virtual track segments are held 'TRUE' if they are already ‘TRUE’ when the train first enters the block, using stick circuits for the near house perspective of the middle track circuits. The vital application can then indicate the true state of the virtual track segment as occupied (FALSE), to protect the train from trains that follow.

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.

A Wireless Slide Fence utilizing signal reflection technology to detect rockslides and can determine the size and location of fallen rocks/objects impeding travel along a train track is presented. The present disclosure solves the technological problem of determining rock size and location to validate rockslide/fall alarms to reduce false alarms, while minimizing repairs required by conventional systems through the use of obstacle detection units and vital logic controllers. The present disclosure improves the performance of the system by, generating validated alarms when fallen rocks/objects satisfy the size criteria and are located in an area hazardous to train operations. In one exemplary embodiment, a loitering time can be implemented to validate object detections to reduce false positives due to transient objects such as migrating animals.
