Rail Transit Track Inspection and Maintenance APTA STANDARDS DEVEL OPMENT PROGRAM APTA RT-FS-S-002-02, Rev. 1 STANDARD First Published: Sept. 22, 2002 American Public Transportation Association First Revision: April 7, 2017 1300 I Street, NW, Suite 1200 East, Washington, DC 20006 Rail Transit Fixed Structures Inspection and Maintenance Working Group Rail Transit Track Inspection and Maintenance Abstract: This standard provides minimum requirements for inspecting and maintaining rail transit system tracks. Keywords: fixed structures, inspection, maintenance, qualifications, rail transit system, structures, track, training Summary: This document establishes a standard for the periodic inspection and maintenance of fixed structure rail transit tracks. This includes periodic visual, electrical and mechanical inspections of components that affect safe and reliable operation. This standard also identifies the necessary qualifications for rail transit system employees or contractors who perform periodic inspection and maintenance tasks. Scope and purpose: This standard applies to transit systems and operating entities that own or operate rail transit systems. The purpose of this standard is to verify that tracks are operating safely and as designed through periodic inspection and maintenance, thereby increasing reliability and reducing the risk of hazards and failures. This document represents a common viewpoint of those parties concerned with its provisions, namely operating/ planning agencies, manufacturers, consultants, engineers and general interest groups. The application of any standards, recommended practices or guidelines contained herein is voluntary. In some cases, federal and/or state regulations govern portions of a transit system’s operations. In those cases, the government regulations take precedence over this standard. The North American Transit Service Association (NATSA) and its parent organization APTA recognize that for certain applications, the standards or practices, as implemented by individual agencies, may be either more or less restrictive than those given in this document. © 2017 NATSA and its parent organization.

  • Flange Facing Machines Applications
    Technical Papers Protem SAS Flange facing machines applications I) DEFINITION AND USE OF A FLANGE FACING MACHINE A Flange Facing Machine also called Portable Lathe is made to mechan- ically polish a disk, collar or ring connected to a pipe in order to form a link with other piping elements (valves, other pipes, etc.) or to block off a part of the piping. This machining operation is done by successive strips to ensure face flatness and regularity. A company needs a Flange Facing Machine when flanges are deformed or corroded due to flows inside a network (water, steam, oil & gas, etc.) and even damaged from outside due to vibrations or bad handlings. Quality of a flange facing is fundamental because sealing and pressure resistance depend on it. II) A FLANGE FACING MACHINE FOR WHICH INDUSTRIES? Flange Facing Machines are needed wherever you can find a flange or a valve, including the following fields: Nuclear Industries Fossil Industries: Oil & Gas (drilling platforms, refineries, offshore, onshore, spool base, etc.) Petrochemical Industry (manufacturing plants of various chemicals) High Purity Diesel Engines Shipyards Tube Processing Defense And generally speaking all industries where mechanical device whose function is to control the flow of fluids in piping systems are present. III) HOW OFTEN IS IT NECESSARY TO REPAIR A FLANGE? There is not a common answer. Indeed, a flange is subject to many preexisting or evolving threats due to: Effect of corrosion Normal and, sometimes, abnormal stresses about bending, pressure, vibrations, etc. Low

    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.

  • Track Geometry
    Track Geometry Track Geometry Cost effective track maintenance and operational safety requires accurate and reliable track geometry data. The Balfour Beatty Rail Digital Track Geometry System is a combined hardware and software application that derives track geometry parameters compliant with EN 13848-1:2003 and is an enhanced version of the original BR and LU systems, with a rationalised transducer layout using modern sensor technology. The system can be installed on a variety of vehicles, from dedicated test trains, service vehicles and road rail plant. Unlike some systems, our solution is designed such that voids and other vertical track defects are identified through the wheel/rail interface when the track is fully loaded. The compromise of taking measurements away from the wheel could produce under-measurement of voided track with an error that increases the further the measurement point is away from the influences of the wheel. The system uses bogie mounted non-contacting inertial sensors complemented by an optional image based sub-system, to measure rail vertical and lateral displacement. The system is designed to operate over a speed range of approx. 5 to 160 mph (8-250km/h). However, safety critical parameters such as gauge and twist will function at zero. Geometry parameters are calculated in real time and during operation real time exception and statistical reports are generated. Principal measurements consist of: • Twist • Dynamic Cross-level • Cant and Cant deficiency • Vertical Profile • Alignment • Curvature • Gauge • Dipped Joints • Cyclic Top Vehicle Ride Measurement As an accredited testing organisation we are well versed in capturing and processing acceleration measurements to national/international standards in order to obtain Ride Quality information in accordance with, for example ENV 12299 “Railway applications – Ride comfort for passengers – Measurement and Evaluation”.
