In one implementation, video images containing detected irregularities on the rail track are transmitted to a control center for further analysis and possible alert.Bar-am, MichaelUS8942426 * Feb 27, 2007 Jan 27, 2015 Michael Bar-Am On-train rail track monitoring system...
The method involves detecting position data of track with two rails (1) geometry in a monitoring region in a continuous sensory manner. The detected position data is evaluated with respect to trafficability and/or maximum permissible run-over speed of a rail track system in the monitoring region...
An automatic inspection system is provided for monitoring rail track for detecting and generating alerts for certain hazards to the operation of trains that may cause various safety concerns and even derailment. The monitoring is during normal railway service runs without interrupting the normal railway...
aA system for monitoring the passage of trains on a rail track by measuring train length, employs track circuits which detect the presence of any part (wheel axle) of a train in any part of the track-circuit. A distance indication of the overlap of train and track-circuit is provided by...
Using Acceleration Signals Recorded on a Railway Vehicle Wheelsets for Rail Track Condition Monitoring The subject matter of the paper is the partial analysis of the results of acceleration signals from the prototype of Rail Vehicles and Rail Track Monitoring System exploitation The prototype of the ...
28, 2023, when a passenger train smashed into an oncoming cargo train put onto the same track and heading in opposite directions. It was Greece’s deadliest railway disaster. Many of the 57 people killed were university students heading back to class after a public holiday. Related ...
To improve the overall safety and effectiveness of railway operations, the concept described in this abstract presents a comprehensive railway infrastructure monitoring and safety system that makes use of state-of-the-art technology. In order to actively identify railway track cracks and deliver real-...
A system and method for detecting and measuring rail and/or track defects may comprise: an array of time-of-flight distance measuring sensors measuring distance to the rail head; wherein the distance measuring sensors are synchronized and the dimensional data therefrom is geo-tagged. A memory sto...
Research and development of monitoring system for railway track condition : 1st report; Easy method for measuring of wheel/rail contact forces Measurement of wheel/rail contact forces, such as wheel load and lateral force is very important for railway safety, but it is difficult to measure them....
The rail fastening system is an important part of a high-speed railway track. It is always critical to the operational safety and comfort of railway vehicles. Therefore, the condition detection of the rail fastening system, looseness or absence, is an important task in railway maintenance. Howeve...
