MÁV Central Rail and Track Inspection Ltd
MÁV Central Rail and Track Inspection Ltd. PATER TRACK DIAGNOSTIC EXPERT SYSTEM Besides the knowledge of quality the safe and economical maintenance of railway tracks plays an increasingly impor- tant role these days. The „PATER” track diagnostic ex- pert software is intended to fulfil this task. PATER is a computer program that keeps records of rail- way tracks, monitors their condition and performs mainte- nance planning duties. Its purpose is to assist track mainte- nance professionals in managing the data of the technical and measurement systems, presenting the condition of the track, planning track maintenance jobs depending on track conditions, selecting the appropriate technology and per- forming cost estimates. Rail defects revealed by various inspections This is a client-server based program that ensures that data and their qualification stored in the database can be accessed from anywhere and client users can use them through the internet in case of sufficient authorisation. This model makes it possible that all data is stored and updated in one location therefore the data available to users is always up-to-date. In the engineering practice the val- ues of the isolated defects and gen- eral qualifying indices are analyzed and these values are sufficient to judge the traffic safety and quality. Nowadays we use track geometri- cal, vehicle dynamical, ultrasonic, Space and time based graphical analysis Head Checking, rail profile and rail of track geometry data corrugation measuring devices. The PATER program adapts to the re- quirements of any railway company: unlimited new measuring system, parameter, measuring limit etc. can be integrated quickly and easily. -

Overview of Wheel/Rail Load Environment Caused by Freight Car Suspension Dynamics
34 TRANSPORTATION RESEARCH RECORD 1241 Overview of Wheel/Rail Load Environment Caused by Freight Car Suspension Dynamics SEMIH KALAY AND ALBERT REINSCHMIDT It has been a well-established fact that excessive wheel/rail loads dynamic load factors that represent only the effects of max cause accelerated wheel/rail wear, truck component deterioration, imum dynamic load conditions (7). The most serious problem track damage, and increased potential for derailment. The eco with these types of assumptions is that they neither make any nomic and safety impact of the increased wheel rail loads can only distinction for the effects of suspension design used in differ be ascertained by a total characterization of the wheel/rail loads. In this paper, a comprehensive set of experimental results obtained ent types of freight cars nor describe the variety of track from on-track testing of conventional North American freight cars conditions found in revenue service. Ideally, for design of using both wayside and on-board measurement systems are pre track and fretgh:t car structures, a total description of the load sented. The particular emphasis is given to the wheel/rail loads spectra including low-frequency high-dynamic loads should resulting from suspension dynamics. The dynamic wheel/rail envi be used (8). ronment addressed in this paper is limited to dynamic performance Our purpose in this paper is to provide an overall under regimes such as rock-and-roll and pitch-and-bounce, hunting, and standing of the dynamic load environment encountered under curving. The strong dependence of the dynamic response of a railway vehicle on a truck suspension system has been illustrated typical North American freight cars. -

Technical Investigation Report on Train Derailment Incident at Hung Hom Station on MTR East Rail Line on 17 September 2019

This report presents the results of the Electrical and Mechanical Services Department’s (EMSD) technical investigation into the causes of the incident. The investigation of EMSD revealed that the cause of the derailment was track gauge widening1. The sleepers2 at the incident location were found to have various issues including rotting and screw hole elongation, which reduced the strength of the sleepers and their ability to retain the rails in the correct position. The track gauge under dynamic loading of trains would be even wider, and this excessive gauge widening caused the train to derail at the time of incident. After the incident, MTR Corporation Limited (MTRCL) have reviewed the timber sleeper condition across the entire EAL route and replaced the sleepers of dissatisfactory condition. MTRCL were requested to enhance the maintenance regime to closely monitor the track conditions with reference to relevant trade practices to ensure railway safety. -
