A system includes a locator device and one or more processors operably connected to the locator device. The locator device determines a trailing distance between a trailing vehicle system that travels along a route and a leading vehicle system that travels along the route ahead of the trailing vehicle system in a same direction of travel. The one or more processors compare the trailing distance to a first proximity distance relative to the leading vehicle system. In response to the trailing distance being less than the first proximity distance, the one or more processors set a permitted power output limit for the trailing vehicle system to be less than a maximum achievable power output for the trailing vehicle system, the permitted power output limit being set based on a power-to-weight ratio of the leading vehicle system.

A system for monitoring a grade crossing is provided. The system may include a sensor co-located with a signage apparatus. The sensor may include a sensing area covering a portion of the grade crossing and a processor communicatively coupled to the sensor. The processor may be configured to receive data originating from the sensor and transmit said data to an analytics module communicatively coupled to the system.

A railroad crossing indication device (250) includes a processing unit (350) for receiving and processing data provided by a constant warning time device (40) in communication with a railroad track (20), wherein the data relate to a train approaching the railroad crossing, and a screen unit (300, 400, 500) for displaying information of the train approaching the railroad crossing based upon the data provided by the constant warning time device (40). Furthermore, a railroad crossing indication system (200) and a method (600) for displaying information at railroad crossings are disclosed.

A bidirectional overhead urban transport (TUEP) for a large transportation capacity, which is suspended over a series of poles, without interfering with the traffic of vehicles and pedestrians surface, which is characterized by having a continuum of autonomous cabins circulating about a tubular track suspended by static wires hanging from the poles. The system has overhead stations for passengers, by which access is given to the suspended cabins, moved by autonomous and independent electric motors which rotate a drive pulley rolling on the upper back of a horizontal tubular track raised or inclined according to the topography of the ground. The peculiarity of this transport system is that each of the cabins that are only for two passengers, travels directly to a destination station, where is diverted from the main flow to a station, so it is not necessary to stop the main flow of cabins, which results in the although circulating at low to moderate speed, the time required to travel is reduced.

An automated warning time inspection system and method to test a warning time at a railroad grade crossing on each route for a train. The automated warning time inspection system comprises a track circuit configured to activate when a train enters the track circuit, an event recorder configured to record a first log time for activation of a crossing warning system, a camera to detect a first motion detection indication in a motion detection zone of the camera if there is any motion and an island circuit to detect a presence of the train as the train enters an island. The event recorder to record a third log time for switch position indications when present. The event recorder to record a fourth log time for activation of the island circuit. The camera to detect a second motion detection indication in the motion detection zone of the camera after the activation of the island circuit if there is any motion. The event recorder to calculate and record a warning time as a difference between the first log time and the third log time and based on a motion detection before or after the activation of the island circuit and whether the warning time was more than or equal to a threshold time and whether the train was travelling more than or equal to a threshold speed a passing or a failing of the warning time inspection is logged into the event recorder in a given route of the train travelling on the train track.

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.

A detection and warning system is provided for a railroad crossing. The system comprises a sensor configured to be mounted on an underside of a gate arm of a railroad crossing gate to detect a presence of a vehicle or other object that is obstructing the railroad crossing. The system further comprises a communication interface coupled to the sensor. In response to a detection of the vehicle or the other object, the communication interface to relay a warning signal indicative of a possible collision on the railroad crossing with the vehicle or the other object.

A system includes a locator device, a communication circuit, and one or more processors, all disposed onboard a trailing vehicle system that travels along a route behind a leading vehicle system. The locator device determines a location of the trailing vehicle system. The communication circuit periodically receives a location of the leading vehicle system in a message. The processors monitor a trailing distance between the trailing vehicle system and the leading vehicle system based on the respective locations of the leading and trailing vehicle systems. Responsive to the trailing distance being less than a first proximity distance relative to the leading vehicle system, the processors set an upper permitted power output limit for the trailing vehicle system that is less than an upper power output limit of the trailing vehicle system to reduce an effective power-to-weight ratio of the trailing vehicle system.
