Modern Tendencies in Vehicle-Based Condition Monitoring of the Railway Track

IEEE Transactions on Instrumentation and Measurement, 2023
Condition monitoring (CM) describes the continuous observation of a dynamical system or process in order to track the evolution of its state and to detect signs of faults in an early stage. It constitutes the core block for performing fault diagnosis and

Anchor‐adaptive railway track detection from unmanned aerial vehicle images

Comput. Aided Civ. Infrastructure Eng., 2023
Autonomous railway inspection with unmanned aerial vehicles (UAVs) has huge advantages over traditional inspection methods. As a prerequisite for UAV‐based autonomous following of railway lines, it is quite essential to develop intelligent railway track ...

Estimation of railway track longitudinal irregularity using vehicle response with information compression and Bayesian deep learning

Comput. Aided Civ. Infrastructure Eng., 2021
In railway transportation, track geometry irregularity is one of the main factors in controlling train safety. At present, railway practitioners typically use the track geometry car (TGC) based on the inertial navigation system to inspect track ...

Railway tracks

2021
Abstract Many factors influence the safe and efficient operation of railway tracks throughout the world. The most important tasks for railway track engineers are the design, installation and maintenance of a highly stable track network that will reliably carry goods and passengers with safety and high speed.

Railway track longitudinal force model

Vehicle System Dynamics, 2021
Most railway track dynamics models focus on vertical and lateral directions. Vehicle dynamics have strong implications for track longitudinal dynamics, but railway track longitudinal force models are rarely published.

Obstacle detection in dangerous railway track areas by a convolutional neural network

Measurement science and technology, 2021
The obstacle detection in the dangerous area of railway track is an important research direction in the field of the driverless train. Traditional obstacle detection methods have many issues, such as complicated steps, low detection accuracy, and slow ...

Analytical study on high-speed railway track deformation under long-term bridge deformations and interlayer degradation

, 2021
Bridges are subjected to long-term deformations in addition to deformations under design loads. In high-speed railway bridges, long-term bridge deformation and potential degradation of materials may adversely impact the operation safety and riding ...

MUHAFIZ: IoT-Based Track Recording Vehicle for the Damage Analysis of the Railway Track

IEEE Internet of Things Journal, 2021
Fault diagnosis plays a major role in railway condition monitoring, as early diagnosis of the emerging faults can save valuable time, reduce maintenance costs and, most significantly, help save people’s lives.
