A method and an apparatus for a train control system are disclosed, and are based on virtualization of train control logic and the use of cloud computing resources. A train control system is configured into two main parts. The first part includes physical elements of the train control system, and the second part includes a virtual train control system that provides the computing resources for the required train control application platforms. The disclosed architecture can be used with various train control technologies, including communications based train control, cab-signaling and fixed block, wayside signal technology. Further, the disclosure describes methodologies to convert cab-signaling and manual operations into distance to go operation.

A robust system processor comprising three parallel processors, each configured to process in parallel an input and emit an output; and a reconciler that compares the three outputs, determines whether at least two of the outputs are equal, and if so validates the majority output and communicates the validated output via a network to at least one other system processor.

A method for controlling a train (10) of railway working vehicles (11) comprising at least two railway working vehicles (11) forming a railway train (10); each of said at least two railway working vehicles (11) comprises a multifunction vehicle bus MVB (20), and a wired train bus WTB (12), which enables connection of said multifunction vehicle buses MVB (20) of said at least two railway working vehicles (11); said multifunction vehicle bus MVB (20) comprises: a train-communication-network TCN port (14)7 which connects said wired train bus WTB (12) to said multifunction vehicle bus MVB (20); a traction control (22) of the means; and a translator (21), which connects said TCN port (14) to said traction control (22); said method being characterized in that: each vehicle of the train writes its own maximum speed on its own TCN port (14); the maximum speed of the train is defined as the lowest of the maximum speeds defined on the TCN ports (14) by the individual vehicles; the master vehicle activates the traction control handle; the master vehicle sends on the TCN port (14) the predefined speed lower than or equal to the maximum speed of the train that is to be reached according to the setting of the traction handle; and all the vehicles of the train detect the pre-set speed that is to be reached and contribute to traction until said speed is reached, regulating their speeds with torques that may even differ from one vehicle to another.

A system includes a safety mode activation device disposed onboard a vehicle system and operatively connected to a controller of the vehicle system. The safety mode activation device is configured to receive a status signal indicating a presence of one or more of an operator or an active work marker in a location proximate to the vehicle system. The safety mode activation device is further configured to transmit a lockout signal to the controller to prevent movement of the vehicle system along a route responsive to receiving the status signal.

A locomotive communication system includes a lead communication device wirelessly communicating command messages to remote communication devices onboard a rail vehicle system during a messaging cycle. The lead device receives reply messages from the remote devices during the messaging cycle in response to the command messages. The lead device receives a status signal from at least one of the remote devices during a guard interval that follows completion of the messaging cycle. The lead device communicates the command message and receives the reply messages using analog modulation or digital modulation. The lead communication device also receives the status signal using the other of the analog modulation or the digital modulation. The command messages, the reply messages, and the status signal are communicated using a designated frequency channel.

A train control system comprising a track switch controller; RFID tags located at first and second track switches coupled via a length of track that store characteristics of train sets as they pass the track switches, and RFID tag readers located on the train sets, connected to a network. The train sets write data to the RFID tags such that the data is read by RFID tag readers of subsequent trains; and the data stored in the RFID tags is overwritten with new data each time a train set passes by the RFID tags.

A positive train control system and method may comprise one or more switch monitors and/or one or more track monitors providing sensor data relative to one or more switches and/or one or more tracks, respectively, determining whether there is an anomaly of a switch or track, and when there is, providing a message, alert and/or warning, and/or initiating a train control action. Determination of an anomaly may be preformed on a train or at a remote location, e.g., a central facility.

System includes a control system used to control operation of a vehicle system as the vehicle system moves along a route. The vehicle system includes a plurality of system vehicles in which adjacent system vehicles are operatively coupled such that the adjacent system vehicles are permitted to move relative to one another. The control system includes one or more processors that are configured to (a) receive operational settings of the vehicle system and (b) input the operational settings into a system model of the vehicle system to determine an observed metric of the vehicle system. The one or more processors are also configured to (c) compare the observed metric to a reference metric and (d) modify the operational settings of the vehicle system based on differences between the observed and the reference metrics.

A vehicle control system and method may include one or more processors that may receive a data set associated with plural waypoint locations along one or more routes. The data set may indicate plural waypoint locations, target arrival time windows for a vehicle system to reach the plural waypoint locations, and priority ranks of the plural waypoint locations. The processors may create and/or adjust a pacing trip plan based on the data set. The pacing trip plan may designate one or more operational settings of the vehicle system as a function of time, distance, and/or location. The pacing trip plan may be created and/or adjusted to direct the vehicle system to reach one or more of the plural waypoint locations within the corresponding target arrival time windows.

A system includes a safety mode activation device disposed onboard a vehicle system and operatively connected to a controller of the vehicle system. The safety mode activation device is configured to receive a status signal indicating a presence of one or more of an operator or an active work marker in a location proximate to the vehicle system. The safety mode activation device is further configured to transmit a lockout signal to the controller to prevent movement of the vehicle system along a route responsive to receiving the status signal.
