摘要： There is provided a track current suppression device. An exemplary device includes an input coupled between rails of a railway track and configured to receive an input voltage corresponding to a track current. The exemplary device also includes an amplifier configured to receive the input voltage and generate a cancellation current. The exemplary device also includes an output coupled between the rails of the railway track and configured to deliver the cancellation current to the rails with reversed polarity compared to the track current.

摘要： An electric rail system includes a current collector mounted for movement along at least one rail of the electric rail system and a monitoring system for detecting a condition indicative of a problem with the rail system or the current collector. The monitoring system includes a detector having one or more of: a camera configured to record images of a portion of the rail system in front of or behind the current collector, at least one vibration sensor on at least one slip contact of the current collector, an optical spark sensor configured to detect sparks in a contact region between the slip contact and the at least one rail, and at least one distance sensor configured to detect a distance between the at least one distance sensor and the at least one rail.

摘要： A train approach detector uses frequencies in the audio spectrum to activate grade crossing protection devices in advance of and during the presence of railroad trains at grade crossings. The detector is completely solid state, and includes one transmitter and one receiver each connected to the tracks so that transmitted and received track signals, which are partially pulse modulated for optimum filtering and signal coupling and minimum third harmonic radiation, appear on opposite sides of the crossing. The section of track between the transmitter and receiver is designated as a crossing island and sections of rail outside of the island are known as approaches. In addition to its basic train movement detection function, the detector contains additional features that are designed to provide operation under a variety of application conditions, including automatic ballast compensation, loss of shunt, low signal/low gain condition, high signal/broken rail condition, delayed pick-up, delayed drop-out and reverse switch override, and bi-directional motion detection.

摘要： Electric railway systems are disclosed. In an embodiment, the electric railway system includes a continuous conductor, access points, connections, and a microwave link. The continuous conductor runs along the railway track for supplying high-voltage power to trains travelling on the railway system, and supplies high-voltage power to trains travelling on the electric railway systems. The continuous conductor is arranged as an overhead line suspended from poles or towers distributed along the railway track. The access points provide data communication with trains travelling on the railway system, and are arranged on the poles or towers above the railway track. The connections connect the electric railway system to an electric low-voltage power cable. The microwave link connects the access points.
