Effect of Vehicle Performance at High Speed and High Cant Deficiency
Proceedings of the ASME/ASCE/IEEE 2011 Joint Rail Conference JRC2011 March 16-18, 2011, Pueblo, Colorado, USA JRC2011-56066 EXAMINATION OF VEHICLE PERFORMANCE AT HIGH SPEED AND HIGH CANT DEFICIENCY Brian Marquis Jon LeBlanc U.S. Department of Transportation, Research and U.S. Department of Transportation, Research and Innovative Technology Administration, Volpe Innovative Technology Administration, Volpe National Transportation Systems Center National Transportation Systems Center Cambridge, Massachusetts, United States Cambridge, Massachusetts, United States Ali Tajaddini U.S. Department of Transportation, Federal Rail Road Administration, Office of Research and Development, Washington D.C., United States ABSTRACT The research for this paper was part of work done for the FRA In the US, increasing passenger speeds to improve trip time to support the FRA Railroad Safety Advisory Committee usually involves increasing speeds through curves. Increasing (RSAC) Track Working Group’s Vehicle Track Interaction speeds through curves will increase the lateral force exerted on (VTI) Task Force. The mission of the VTI task force was to track during curving, thus requiring more intensive track update Parts 213 and 238 of the Code of Federal Regulations maintenance to maintain safety. These issues and other (CFR) regarding rules for high speed (above 90mph) and high performance requirements including ride quality and vehicle cant deficiency (about 5 inches) operations. The task force stability, can be addressed through careful truck design. focused on a number of issues including refinement of VTI Existing high-speed rail equipment, and in particular their safety criteria, track geometry standards, vehicle qualification bogies, are better suited to track conditions in Europe or Japan, procedures and requirements and track inspection in which premium tracks with little curvature are dedicated for requirements, all with a focus on treating the vehicle and track high-speed service. -

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. -

Modelling Railway Interlocking Tables Using Coloured Petri Nets
Modelling Railway Interlocking Tables Using Coloured Petri Nets Somsak Vanit-Anunchai School of Telecommunication Engineering Institute of Engineering, Suranaree University of Technology Muang, Nakhon Ratchasima 30000, Thailand [email protected] Abstract. Interlocking tables are the functional specification defining the routes, on which the passage of the train is allowed. Associated with the route, the states and actions of all related signalling equipment are also specified. This paper formally models the interlocking tables us- ing Coloured Petri Nets (CPN). The CPN model comprises two parts: Signaling Layout and Interlocking Control.TheSignaling Layout part is used to simulate the passage of the train. It stores geographic infor- mation of the signalling layout in tokens.TheInterlocking Control part models actions of the controller according to the functions specified in the interlocking tables. The arc inscriptions in the model represent the content of the interlocking tables. Following our modelling approach we can reuse the same CPN net structure to model any new or modified interlocking system regardless of its size. Experimental results are pre- sented to provide increased confidence in the model correctness. Keywords: Control Tables, Railway Signalling Systems, State space analysis, XML, XSLT. 1 Introduction Background. Currently the State Railway of Thailand (SRT) has been under- taking several railway signalling projects involving either improvement of the existing signalling systems or expansion of the existing railway lines. During the whole process of designing, installing and testing the signalling system, “In- terlocking Tables” or “Control Tables” play a vital role. The control table is a tabular representation specifying how the trains move together with the required states and actions of all related equipment. -

Track Geometry Inspection Report Explanation
TRACK GEOMETRY INSPECTION REPORT EXPLANATION An Automated Track Inspection Program (ATIP) Track Geometry Inspection Report (TGIR) is generated for each ATIP survey. The TGIR summarizes the data collected and can be used in conjunction with the strip chart. The TGIR is generated electronically onboard the car and hard copies are distributed as follows: • One (1) copy is provided to onboard railroad representative, as requested • One (1) copy is provided to onboard FRA Inspector, as requested • One (1) copy is archived for FRA management Following ATIP Compliance survey operations, electronic copies of TGIRs are distributed via email, to a list of recipients designated by FRA and railroad management. The TGIR may consist of up to ten parts; • Cover • Notes • Exception List • Curve Analysis • Exception Summary • Track Quality Index (TQI) • GRMS Exception List (if equipped) • Class+1 (C+1) Exception List • C+1 Exception Summary • Alignment 62 Mid-Chord Ordinate (MCO) Stations Track measurement sample frequency is once per foot. An exception is reported when track geometry values exceed the prescribed limit, plus 0.10-inches of grace, for two (2) or more consecutive samples (minimum length of 1- foot). Exceptions are not reported for profile and alinement using 31 and 62 MCO when ATIP car speed is less than five (5) miles per hour. REGULATORY INFORMATION Regulatory information for minimum track geometry safety limits in accordance with the FRA Track Safety Standards (TSS) can be found on the web at: https://www.ecfr.gov/cgi-bin/text- idx?SID=0d4f018b4eac4872f4cec827561c657c&mc=true&tpl=/ecfrbrowse/Title49/49cfrv4_02.tpl#0 Railroad authorized train speed determines the Class of Track, which categorizes the minimum or maximum track geometry requirements. -
