“…Situations with and without active controllers are compared. In these studies, the active pantograph was used to dampen vibrations and positive results were obtained [49][50][51]. Abdullah et al, in his side study, he created a fourth-order independent pantograph mathematical model as an active control system to reduce contact force variation.…”

Today, electric rail systems that use clean energy and are a fast and reliable means of transportation are used more because of their efficiency. The main purpose of new studies investigating pantograph catenary interaction in Electric Rail Systems is to detect malfunctions. With the spread of high-speed trains in electric rail systems, malfunctions occur in pantograph and catenary systems operating under high current and high voltage. The contact force of the pantograph-catenary system erodes the pantograph surface and arcs occur. For this reason, periodic control is mandatory in pantograph-catenary systems. In this study, new, effective, sensitive, stable, real-time applicable and contactless condition monitoring, analysis, control, and diagnostic methods were investigated for pantographcatenary systems that provide energy transmission from the electric line to the locomotive in electric trains. A literature search and study application after has been carried out for modeling a pantograph-catenary system and analysis of system parameters, instantaneous control of the contact force between the pantograph and catenary to diagnose malfunctions in the pantograph-catenary system. It has been observed that pantograph-catenary interaction is negatively affected and the quality of energy transmission decreases if the system parameters change for any reason. In pantograph-catenary systems, the importance of periodic pantograph control, which will ensure the stable and efficient operation of the system, is understood if the parameters change. Because changes in parameters cause malfunctions. Therefore, periodic control and continuous monitoring of the system is required.

“…One of the main problems encountered in today's high-speed trains is the loss of contact between the PCS interface due to vibrations in the catenary, which results in reduced current collection. The pantograph was identified by the least-squares method to reduce contact loss [5]. Wu et al [6] used active control to control the system behavior.…”

To ensure the safe operation of high-speed trains, catenary anomaly detection and alerting security have become an urgent problem to solve. In this paper, we propose a novel method for abnormal behavior localization of a pantograph-catenary for high-speed trains. First, a modified faster RCNN is proposed to detect the pantograph faults. By adjusting the parameters of the faster RCNN, the positional accuracy of the candidate box and accuracy of the algorithm are guaranteed. We perform the arc detection after detecting the pantograph head area. The detection accuracy is over 99%. The height of the pantograph center point is also obtained during detection. Then, the actual running mileage of the fault point is calculated. Experiments show that the method proposed in this paper is also applicable to various complex scenes and that this method can determine the fault localization in the shortest time, narrow the maintenance scope, and improve the overhaul efficiency.

In recent years, the high speed railway vehicle dynamics performances have been studied and investigated in order to determine the ride comfort of the passengers. Most of the time, these researches were involving expensive and high end technology of data logging system to record and analyze the data. In this research, a low cost data logging system (Lego Mindstorms) is used to gather the data from accelerometer and gyro during experimentation. The study about the behaviour of railway vehicle in term of roll and vibrations at three perpendicular axes during running at the curve track is performed. Actual field run of railway vehicle data collection is performed on the available high speed railway vehicle operating from Kuala Lumpur International Airport (KLIA) to the Kuala Lumpur (KL) Sentral. The route selected consists of several curves which are important to study the dynamics performance of the vehicle. The results from experiment establishes the dynamics performances of the railway vehicle in term of passengers ride comfort. With the availability of the data logging system and sensors, the railway vehicle dynamics performance can be analyzed and monitored for future improvement of railway vehicle service and operation.
