Structure Gauge Measuring Equipment Using Laser Range
PAPER Structure Gauge Measuring Equipment Using Laser Range Scanners and Structure Gauge Management System Takashi TOYAMA Signalling Systems Laboratory, Signalling and Transport Information Technology Division Nozomi NAGAMINE Image Analysis and IT Laboratory, Signalling and Transport Information Technology Division Tatsuya OMORI Kenichi KITAO Signalling Systems Laboratory, Signalling and Transport Information Technology Division (Former) Ryuta NAKASONE Image Analysis and IT Laboratory, Signalling and Transport Information Technology Division Periodic measurement of the structure gauge is essential to ensure safe train operation. Measuring the clearance gauge however, is time and labor intensive given the vast number of trackside facilities. An inexpensive and efficient measuring device using laser range scanners was therefore developed. A management system is also being developed, which maps mea- sured three-dimensional point cloud data to facility data. This paper describes the problems and solutions related to applying the laser range scanners for structural gauging, and pres- ents results obtained from experiments. This paper also describes progress achieved in the development of the management system. Keywords: laser range scanner, LiDAR, structure gauge, clearance car, facility management, 3-D point cloud 1.

Cant Deficiency and Negative Superelevation
CANT DEFICIENCY AND NEGATIVE SUPERELEVATION Introduction Cant deficiency is the difference between the equilibrium cant that is necessary for the maximum permissible speed on a curve and the actual cant provided. Cant deficiency is limited due to two considerations: 1. Higher cant deficiency causes greater discomfort to passengers 2. Higher cant deficiency leads to greater unbalanced centrifugal force, which in turn leads to the requirement of stronger tracks and fastenings to withstand the resultant greater lateral forces. The maximum values of cant deficiency prescribed on Indian Railways are given in Table below. Table Allowable cant deficiency Gauge Group Normal cant Remarks deficiency (mm) BG AandB 75 For BG group BG C, D, and 75 For A and B routes; 1 00 mm cant deficiency E permitted only for nominated rolling stock and routes with the approval of the CE MG All routs 50 NG - 40 The limiting values of cant excess have also been prescribed. Cant excess should not be more than 75 mm on BG and 65 mm on MG for all types of rolling stock. Cant excess should be worked out taking into consideration the booked speed of the trains running on a particular section. In the case of a section that carries predominantly goods traffic, cant excess should be kept low to minimize wear on the inner rail. Table below lists the limiting values of the various parameters that concern a curve. NEGATIVE SUPERELEVATION When the main line lies on a curve and has a turnout of contrary flexure leading to a branch line, the superelevation necessary for the average speed of trains running over the main line curve cannot be provided. -

Preface Preface The purpose of a Rail Accident Investigation Branch (RAIB) investigation is to improve railway safety by preventing future railway accidents or by mitigating their consequences. It is not the purpose of such an investigation to establish blame or liability. Accordingly, it is inappropriate that RAIB reports should be used to assign fault or blame, or determine liability, since neither the investigation nor the reporting process has been undertaken for that purpose. The RAIB’s findings are based on its own evaluation of the evidence that was available at the time of the investigation and are intended to explain what happened, and why, in a fair and unbiased manner. -
Technical Investigation Report on Train Derailment Incident at Hung Hom Station on MTR East Rail Line on 17 September 2019
港鐵東鐵綫 紅磡站列車出軌事故 技術調查報告 Technical Investigation Report on Train Derailment Incident at Hung Hom Station on MTR East Rail Line 事故日期︰2019 年 9 月 17 日 Date of Incident : 17 September 2019 英文版 English Version 出版日期︰2020 年 3 月 3 日 Date of Issue: 3 March 2020 CONTENTS Page Executive Summary 2 1 Objective 3 2 Background of Incident 3 3 Technical Details Relating to Incident 4 4 Incident Investigation 8 5 EMSD’s Findings 19 6 Conclusions 22 7 Measures Taken after Incident 22 Appendix I – Photos of Wheel Flange Marks, Broken Rails, Rail Cracks and Damaged Point Machines On-Site 23 1 Executive Summary On 17 September 2019, a passenger train derailed while it was entering Platform No. 1 of Hung Hom Station of the East Rail Line (EAL). 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.
