The present disclosure relates to a train autonomous control system (TACS) based method for train interval protection control, and an apparatus for the method. The method includes: step one: receiving, by a carborne controller (CC), a train operation command sent by an automatic train supervision (ATS) system to obtain a movement mission; step two: calculating, by the CC, a train guaranteed zone in real time according to information of train localization, car characteristics, and carborne controller characteristics; step three: calculating, by the CC, track resources required to be used in combination with current mission information according to the train guaranteed zone, and requesting to a wayside information control (WSIC) for information of collided trains occupying these track resources; and step four: sending, by the WSIC, a list of the collided trains on the track resources required to be used to the CC according to information of the track resources required to be occupied by a train on a whole line. Compared to the prior art, the present disclosure has the advantages of high operation efficiency, communication resource saving, reliability, safety, etc.

The present invention relates to a TACS system supporting a fallback train control mode and a manual fault handling mode. The system supports mixed running operation of a main mode train and a degraded mode train. The main mode is a TACS mode, and the degraded mode includes a fallback mode and a device cut-off mode. The TACS system includes a central train supervision device, a station train dispatching device, a wayside resource management unit RMU, a wayside target controller OC, a data communication system DCS, and an on-board controller CC. Compared with the prior art, the present invention has the advantages of improving the functionality and practicality of the system.

An example locomotive consist control system includes a locomotive controller located on a locomotive consist to control movement of the locomotive consist along one or more tracks, and a field operator control unit in communication with the locomotive controller. The field operator control unit is configured to control movement of the locomotive consist via the locomotive controller. The system also includes a yard supervisory controller configured to monitor a location of the locomotive consist along the one or more tracks, and a remote operator controller in communication with the yard supervisory controller and the locomotive controller. The remote operator controller is configured to transmit speed and direction orders from the yard supervisory controller to the locomotive controller to control movement of the locomotive consist.

A vehicle control system and method includes identifying a segment of a route where one or more first vehicle systems were operated manually instead of operated by one or more processors according to one or more trip plans during prior traversals of the segment by the one or more first vehicle systems. A segment plan is generated for traversing the segment under control of the one or more processors. The segment plan is generated based on how the one or more first vehicle systems were manually operated during the prior traversals of the segment. One or more second vehicle systems are controlled with the one or more processors to traverse the segment according to the segment plan.

According to various aspects, exemplary embodiments are disclosed of systems and methods for safety locking of operator control units for remote control locomotives. In an exemplary embodiment, a system includes a machine control unit located on a locomotive to control operation of the locomotive, a primary operator control unit including a primary network interface configured to transmit received input commands to the machine control unit to control motion of the locomotive, and a secondary operation control unit including a secondary network interface and a secondary input interface. The secondary operator control unit is configured to operate in a secondary role that does not include motion control of the locomotive, and the secondary operator control unit is configured to transmit a lock command to the machine control unit to inhibit movement of the locomotive in response to receiving a lock command input at the secondary input interface.

The present disclosure relates to a train-ground interlocking method and system for rail transit train operation control. In the train-ground interlocking method, a train is taken as a subject of wayside and carborne resource management, and the train actively calculates a required resource according to a “movement mission”, applies to a wayside at an appropriate time and location, uses the resource after obtaining a resource use authority, and actively releases the resource after use of the resource; and once the wayside allocates the resource to one of other trains, the resource cannot be reallocated without being released by the train. Compared to the prior art, the present disclosure has the following advantages: interlocking control of integration of the train and wayside equipment is achieved, rail transit is improved from original passive and indirect interlocking control of the train to active and direct interlocking control of the train, the train safety protection function and the utilization efficiency of wayside resources are further improved, and safe, timely and appropriate match between a movement behavior of the train and a status of the wayside equipment is truly realized.

A method and an apparatus for a train control installation are disclosed, and are based on the absolute permissive block concept. The train control installation employs a plurality of generic absolute block signal units (ABSU), wherein each signal unit includes means for detecting the crossing of a train passed a discrete point, means for exchanging data with adjacent ABSUs, means for generating and communicating a movement authority limit to a train, means for generating and displaying a signal indication, and means for enforcing a stop aspect. The train control installation can be used in conjunction with a communication based train control (CBTC) system to provide a degraded mode of operation without impacting the availability and the reliability of the CBTC system. Further, the train control installation has a self-healing feature to maintain train service during an ABSU failure.
