Systems and techniques for intelligently repairing deviations in the execution of an optimized operating schedule associated with a hub. In embodiments, intelligently repairing deviations in the execution of an optimized operating schedule associated with a hub may include managing hostler-aided multi-hop operations that may be configured to repair the impact of mis-located units within the hub by optimizing the use of hostler resources during execution of the optimized operating schedule to insert multihop operations configured to move or transport the mis-located units from suboptimal locations to optimal locations into hostler route operations, which may improve or reoptimize the unit throughput within the hub over the planning horizon of the optimized operating schedule. In embodiments, an optimal location includes a location that leads to a higher unit throughput for the hub when the unit is located therein than when the unit is located in the current mis-location.

Systems and techniques for intelligently diffusing units across parking lot resources of a hub based on a dual-stream resource optimization (DSRO). In embodiments, a unit diffusion manager intelligently diffuses or spreads units across the parking spots of a parking lot resource to which the units may be assigned based on unit characteristics to maximize unit throughput within the hub. The unit characteristics of a unit include a unit-train assignment identifying the outbound train to which the unit may be assigned, a train-track assignment of the outbound train identifying the production track to which the outbound train is assigned for loading the units onto the outbound train, an identification of the customer to which the unit belongs, and/or other characteristics that may be relevant to the movement of the unit within the hub.

A system and method for automating railroad maintenance by a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables collision avoidance between members of the tie gang performing maintenance on railway assets (e.g., Rails, Ties, Ballasts, Turnouts, Crossings, etc.). The system can generate production numbers for the railway assets and evaluate an asset queue for the tie gang to perform maintenance. The system can utilize real-time updates from the tie gang to optimize work output. The system can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset. The system also provides for a heads-up-display (HUD) to notify an operator of relevant information, such as maintenance information, travel indicators, and updated asset queue. The system can identify a next location and calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics.

A method for controlling a main circuit of a traction system is provided. The method includes: under a braking condition, controlling a protection module to be turned off; controlling the protection module to be turned on and monitoring a first current detected by a first current sensor in a case that a rail vehicle runs on a charged third rail; and controlling the protection module to be turned off and monitoring whether the rail vehicle runs on a charged third rail in a case that the first current is less than a first preset current.

A test release mechanism for a railway switch machine includes a block structured to attach to a lock box in order to move in conjunction with the lock box and a lift pin structured to be operable to selectively engage and disengage the block with a slide bar.

In one embodiment, a method includes receiving first Light Detection and Ranging (LiDAR) data associated with a railroad environment, extracting an asset from the first LiDAR data associated with the railroad environment, and superimposing the asset into a spatial model. The method also includes receiving a field indication associated with a modification to the railroad environment and modifying the spatial model in response to receiving the field indication associated with the modification to the railroad environment. The method further includes receiving second LiDAR data associated with the railroad environment and comparing the second LiDAR data to the modified spatial model.
