Railroad object detection systems and methods include radar sensors detecting object presence, speed and heading in a different manner. A controller compares signal outputs from the different sensors to make real time health assessments and self-diagnose sensor problems in a railroad application. The sensor devices may include an ultra-wideband (UWB) impulse radar device and at least one reflective device providing failsafe object presence detection and object non-presence detection in redundant fashion with at least a second sensor device such as a side-fired radar device.

A control arrangement for a railroad level crossing is disclosed. The control arrangement comprises monitoring sensors for monitoring the level crossing, the monitoring sensors arranged to detect an obstruction within a restricted area at or near to the level crossing, and a processing unit associated with the monitoring sensors and arranged to generate an alarm warning when an obstruction is detected. The alarm warning is used to adjust a Movement Authority issued to a train approaching the level crossing.

An information sharing system derives from a roadway vehicles management system position-related data of a roadway vehicle along a road and determines a roadway vehicle timing at or during which the roadway vehicle is estimated to arrive at or cross a railway crossing. The information sharing system further derives from a railway vehicles management system position-related data of a railway vehicle along the railway and determines a railway vehicle timing at or during which the railway vehicle is estimated to arrive at or have passed the railway crossing. The information sharing system determines, based on comparing a roadway vehicle time window to a railway vehicle time window, that the roadway vehicle time window and the railway vehicle time window at least partly overlap. The information sharing system provides information associated with the overlap to the roadway vehicle or the railway vehicle.

A railway crossing programmable device includes a communication module in signal communication with a central server for authentication of a user to use the programmable device to modify the railway system circuit. The programmable device further includes a circuit modification module configured for electrical coupling to a railway system circuit for modifying an electrical connection of the railway system circuit in a programmed manner. The programmable device further includes a user interface configured to receive user data and display output information related to at least one of a user, a device, and a circuit modification.
