Abstract: Systems and methods for determining cable routes of a railway infrastructure are described herein. A graphical user interface for interacting with graphical representations of railway infrastructure on a map interface is operated. A request for at least one cable route between a first position and a second position of the railway infrastructure is received. Railway infrastructure information indicative of configuration of the railway infrastructure between the first position and the second position is obtained. The at least one cable route is determined based on the railway infrastructure information. The at least one cable route is displayed on the graphical user interface.

The present disclosure describes a brake system for a track section of a linear motor system. The brake system includes a housing receiving a brake flag of a mover and a first brake pad disposed within the housing and having a first tapered surface. The brake system also includes a second brake pad disposed within the housing and having a second tapered surface and a wedge disposed within the housing and comprising a third tapered surface. The brake system also includes an actuator that moves the wedge, wherein movement of the activation wedge causes the first brake pad to move and causes the second brake pad to move.

A universal retarder system for slowing a railcar on rails. The system includes a lever arm configured to be pivotable within a vertical plane, where the lever arm is configured to support a brake shoe. An engagement device is coupled to the lever arm and configured to pivot the brake shoe towards one of the rails. A disengagement device is coupled to the lever arm and configured to pivot the brake shoe away from the one of the rails. The lever arm, engagement device, and disengagement device are each positioned between the rails. Pivoting the brake shoe towards the one of the rails is configured to force the brake shoe into engagement with the railcar to slow the railcar.

A system for retarding a railcar. The system includes a brake and an actuator that moves the brake between a closed position in which the brake slows the railcar and an open position in which the brake does not slow the railcar. The system further includes a hydraulic circuit through which a hydraulic fluid flows between the actuator, a pump, and a reservoir. A variable speed motor drives the pump to supply the hydraulic fluid from the reservoir to the actuator. The variable speed motor is operable at a plurality of speeds between fully-on and fully-off states. A control system determines a speed setting within the plurality of speeds for operating the variable speed motor based on a pressure of the hydraulic fluid in the hydraulic circuit, the speed setting being determined such that the pressure is sufficient for operating the actuator.

Systems and methods for determining braking distances and systems and methods for positioning of wayside signals are described herein. A graphical user interface is operated for selecting at least one wayside signal of a railway. At least one selected wayside signal is received via the graphical user interface. Railway parameters indicative of a configuration of the railway and one or more rail transit vehicles operable on the railway are obtained based on the at least one selected wayside signal. At least one braking distance is determined based on the railway parameters and the at least one selected wayside signal. The at least one braking distance is displayed on the graphical user interface.

Systems and methods related to railway management systems with data repositories are described herein. A graphical user interface including a map interface of a railway infrastructure is provided. A request for information is obtained via a graphical element displayed on the map interface, the graphical element corresponding to a component of the railway infrastructure. Railway infrastructure information is obtained from a data repository based on the request. The railway infrastructure information is displayed on the graphical user interface.
