A remote controlled light adjustment device includes a horizontal adjustment arm, a vertical adjustment arm, a mounting base comprising multiple anchor points for coupling the horizontal adjustment arm and the vertical adjustment arm to the mounting base, and a remote control, wherein the mounting base, the horizontal adjustment arm and the vertical adjustment arm are configured to be mounted to a light device, and wherein the horizontal adjustment arm and the vertical adjustment arm are configured to move the light device based upon signals transmitted by the remote control and received by the mounting base.

Remote controlled light adjustment device and associated method

To locate a shunt, the shunt includes an RF transmitter configured to wirelessly transmit an identifier of the shunt such as the configured shunt frequency. The shunt may include switches or memory locations that may be configured by an installer to correspond to the configured shunt frequency. Other embodiments employ switches or sensors influenced by jumpers installed in the shunt to configure the frequency of the shunt. A portable device receives a transmission including the identifier and displays it along with an indication of the received signal strength of the transmission, and maintenance personnel move the portable device along the track to locate the highest received signal strength, which indicates the location of the shunt. The shunt may also include a test circuit that may be configurable to generate a test frequency, determine a parameter indicative of shunt performance, and output a signal based on the parameter.

Aspects of the disclosed embodiments generally relate to railway track circuits, in particular track circuits with continued distance monitoring and broken rail protection.

Track circuit with continued distance monitoring and broken rail protection

A railroad crossing control system () includes a constant warning time device () with a control unit () configured to produce multiple signals, and a wheel sensing system () comprising at least one sensor () connected to a rail () of a railroad track () at a predetermined position (P), wherein the wheel sensing system () detects a presence of railroad vehicle travelling on the railroad track () such that the at least one sensor () detects wheels of the railroad vehicle using electromagnetic fields, wherein the wheel sensing system () provides speed values of the railroad vehicle to the constant warning time device (), and wherein the constant warning time device () produces a constant warning time signal for controlling a railroad crossing warning device in response to receiving the speed values of the wheel sensing system ().

There is described systems and methods for managing an electrical surge of railway signaling equipment. A breaker includes a mechanical reset button that shifts positions in response to detecting the electrical surge exceeding a threshold amperage. An opto-isolator deenergizes in response to the position shift of the mechanical reset button. The event recorder transmits an alarm signal to a remote office system in response to the deenergizing of the opto-isolator.

A traffic control system () includes a railroad crossing control system () with a constant warning time device (), a wheel sensing system () with a sensor () connected to a rail () of a railroad track () at a predetermined position (P), and a communication network () interfacing with the railroad crossing control system () and the wheel sensing system () and adapted to transmit data. The wheel sensing system () provides speed values of a rail vehicle travelling on the railroad track (), wherein the speed values are transmitted to the railroad crossing control system () via the communication network () for producing a preemption signal for the traffic signal control system (). Further, a method for providing a preemption signal for a traffic signal control system () is described.

A railway road crossing warning system () including a railway road crossing control unit () that may be selectively set to a primary or a secondary mode of operation is provided. In the primary mode of operation, the railway road crossing control unit is responsive to a primary activation signal () received from a primary activation-signal source (), such as a positive train control (PTC) system. In the event the primary activation signal from the primary activation-signal source is not available, railway road crossing control unit () is set to the secondary mode of operation, where the railway road crossing control unit is responsive to one or more signals () received from a secondary activation-signal source () including a railway-vehicle sensing system () electrically-decoupled from a railroad track (). Disclosed embodiments maintain operational robustness in the presence of changing weather and avoid variable electrical ballast conditions that otherwise could develop across the rails, while providing a cost-effective and reliable backup capability for a PTC-started crossing system.

Systems and methods for detecting the dynamic train-to-rail shunting performance of a train as it is moving along the rails of a railroad track. The systems and methods use portable equipment temporarily installed at a site where it is desired to test the shunting of one or more trains or the electrical equipment installed at the track. The systems and method use sensor plates and a high speed recording system to simultaneously capture measured train-to-rail shunting characteristics and the positioning of a train's axles and any rail conditions impacting the measurements. The captured information can be used to fine tune the train, the electrical equipment installed at the track and/or to design new devices.

A cover plate for a junction box may include a plate portion configured to cover an opening of the junction box. The cover plate may include a mast portion configured to couple with equipment configured to be mounted on a mast. The cover plate may include an offset portion coupling the mast portion with a front side of the plate portion.

A track test load device includes an inductor assembly with simulated track inductors simulating a rail track, a connector assembly for connecting the inductor assembly to a constant warning time device, and a multi-way-switch-assembly with a multi-way-switch with multiple switch positions. The multi-way-switch assembly is operably coupled between the inductor assembly and the connector assembly, wherein a switch position of the multi-way-switch corresponds to an operating mode of the track test load device. Furthermore, a track test load system and a method for testing a constant warning time device are disclosed.
