Abstract:

The proposed Railway Track Management System is designed to detect faults in railway tracks by continuously monitoring track vibrations using accelerometers installed along the track. These accelerometers measure the vibrations caused by passing trains and other environmental factors. When an abnormal vibration pattern indicative of a track fault is detected, the system triggers an alarm using a buzzer and displays a message on an LCD screen located at the control center. One of the key features of the Railway Track Management System is its ability to identify various types of track faults, in

ABSTRACT: Rail is one of the most energy efficient and economical modes of transportation. Regular rail- way track health inspection is an essential part of a robust and secure train operation. Delayed investigations and problem discoveries pose a serious risk to th e safe functioning of rail transportation. The traditional method of manually examining the rail track using a railway cart is both inefficient and susceptible to mistakes and biasness. It is imperative to automate inspection in order to avert catastrophes and save countless lives, particularly in zones where train accidents are nu

Abstract:

A large part of the noise emissions from rail traffic originates from rolling noise. This is significantly determined by the surface roughness of the wheel and the rail. To quantitatively assess the noise generation from the wheel–rail contact, it is necessary to measure the surface roughness of the rail network. Direct measurements via trolley devices are usually associated with the need for a free track and limitation in velocity. Indirect measurements of rail roughness, such as measuring axle-box accelerations, enable operation during regular passage but only estimate the acoustic roughness

Abstract:

In Indonesia, trains are one of the most popular means of transportation for Indonesians to help with the mobility of passengers and goods. However, train derailment is also something that happens quite frequently. The train derailment was caused by several factors, the rail line damage is one of the biggest possible causes. For this reason, it is necessary to carry out inspections on it to detect and find defects on the rails for subsequent repairs. Manual inspections, as is still often done by officers in Indonesia, have shortcomings such as low efficiency, human error, and danger. Automatic

Abstract:

With increases in train speed and traffic density, problems due to wheel polygons and those caused by wheel–rail impacts will increase accordingly, which will affect train operational safety and passenger ride comfort. This paper investigates the effects of polygonal wheels on the dynamic performance of the track in a high-speed railway system. The wheel–rail interaction forces caused by wheel polygons are determined using a dynamic vehicle–track model, and the results are entered into a slab track finite element model.

The proposed IoT-enabled crack detection system enhances railway safety by addressing undetectedrail track cracks that can lead to derailments and economic losses. This innovative solution utilizesautomated anomaly detection, geolocation tracking, and cloud-based analytics through a compactautonomous robotic unit that traverses rail tracks to identify surface and sub-surface defects withhigh precision.

Abstract:

Measurement of wheel/rail contact forces is of importance. Traditional methods for wheel/rail interaction force measurement all need strain gauges on wheel sets and/or rails. Because strain gauges have the performances of zero-drift, poor anti-interference property and instability of test system, they can’t meet wheel/rail force test requirements in high-speed and heavy haul railways. A new method based on PVDF piezoelectric sensing technology is presented for the test of vertical and horizontal wheel/rail force in this paper. Firstly, based on the wheel/rail interaction characteristics, the r

Abstract:

The operation safety of railway transport, which is the most important economic and social factor, is largely determined by the technical condition of the rail track and measures to maintain the quality of its track management system. One of the system elements for ensuring the accident-free operation of the track is the technical diagnosis of rails using a method complex of non-destructive control of rails, such as acoustic (ultrasonic), magnetic, combined, etc., and monitoring of the track using methods of measuring the geometry of the rail track and its disturbances.

Abstract:

Automatic obstacle detection is of great significance for improving the safety of train operation. However, the existing autonomous operation of trains mainly depends on the signaling control system and lacks the extra equipment to perceive the environment.

Excessive rail displacements can result in reduced rail traffic speeds and increased risk of derailments. A number of methods exist for the measurement of vertical rail displacements, including using geophones, high-speed cameras, and rail vehicle mounted systems. The advantage of rail vehicle mounted methods is that large lengths of track can be assessed. However, there are some instances where the measurement of absolute rail deformations is essential, particularly in poor subgrade conditions where significant long-term settlements are possible.

Recent train accidents have reaffirmed the need for developing a rail defect detection system more effective than that currently used. One of the most promising techniques in rail inspection is the use of ultrasonic guided waves and noncontact probes.

The prototype includes an algorithm based on wavelet transform and outlier analysis. The discrete wavelet transform is utilized to denoise ultrasonic signals and to generate a set of relevant damage

Abstract:

To make full use of the massive monitoring data accumulated in China high-speed railways, an improved statistical process control (SPC) framework was introduced to analyze the discontinuous monitoring data of the track system on a high-speed railway elevated station. Multilinear regression models and time series difference equation (TSDE) models were first developed to separate common-cause variations in the monitoring data. Then, individual control charts, moving range control charts, and exponentially weighted moving average control charts were constructed to detect special-cause variations.

In this method, the track strain response upon wheel-rail interaction is measured and processed to generate a condition index which directly reflects the wheel condition.
