  • Clearance of Derailment Guards in Metro Systems 1. As Per Para 7.1 Of
    Annexure‐XII Clearance of derailment guards in Metro systems 1. As per para 7.1 of ‘Standards of Track structures for Metro Railway/MRTS system’, the derailment guard should be provided inside/outside of running rail, and the lateral clearance between the running rail and the derailment guard shall be 250±40mm. Thus the maximum clearance permitted is 290mm, and the minimum is 210mm. In the following paras, the impact of this clearance on the safe operation of Metro systems has been analysed. Analysis has also been made to arrive at the minimum up‐stand clearance required to accommodate the various Fastening systems approved for use in the Metro systems. Based on the above analysis, recommendations for the up‐stand clearance has been arrived at. The impact of up‐stand clearance on minimum plinth width requirement has also been brought out. 2. As per SoD generally adopted by Metro systems, the following track and Rolling stock parameters adopted by Metro systems have been taken for the analysis. 2.1. Track. Gauge‐1435mm Rail head width(UIC 60)‐72mm Rail height(UIC 60) ‐172mm. Up‐stand thickness‐200mm 2.2. Rolling stock wheel set. Wheel gauge back to back distance‐1360mm Minimum projection of flange of new wheel‐28mm Maximum projection of flange of worn wheel‐36mm Maximum thickness of wheel flange‐32.5mm Minimum thickness of wheel flange‐22mm Minimum width of wheel‐135± 2.3. Wheel flange clearance to rail gauge face When the wheel set is in central position with respect to track, the clearance between rail and wheel works out to (1435‐1360‐ 2x32.5)/2=5mm.

  • Finished Vehicle Logistics by Rail in Europe
    Finished Vehicle Logistics by Rail in Europe Version 3 December 2017 This publication was prepared by Oleh Shchuryk, Research & Projects Manager, ECG – the Association of European Vehicle Logistics. Foreword The project to produce this book on ‘Finished Vehicle Logistics by Rail in Europe’ was initiated during the ECG Land Transport Working Group meeting in January 2014, Frankfurt am Main. Initially, it was suggested by the members of the group that Oleh Shchuryk prepares a short briefing paper about the current status quo of rail transport and FVLs by rail in Europe. It was to be a concise document explaining the complex nature of rail, its difficulties and challenges, main players, and their roles and responsibilities to be used by ECG’s members. However, it rapidly grew way beyond these simple objectives as you will see. The first draft of the project was presented at the following Land Transport WG meeting which took place in May 2014, Frankfurt am Main. It received further support from the group and in order to gain more knowledge on specific rail technical issues it was decided that ECG should organise site visits with rail technical experts of ECG member companies at their railway operations sites. These were held with DB Schenker Rail Automotive in Frankfurt am Main, BLG Automotive in Bremerhaven, ARS Altmann in Wolnzach, and STVA in Valenton and Paris. As a result of these collaborations, and continuous research on various rail issues, the document was extensively enlarged. The document consists of several parts, namely a historical section that covers railway development in Europe and specific EU countries; a technical section that discusses the different technical issues of the railway (gauges, electrification, controlling and signalling systems, etc.); a section on the liberalisation process in Europe; a section on the key rail players, and a section on logistics services provided by rail.

  • Railway Route Design Parameters Outline Gauge
    Trans-AsianRailwav in the Indo-China and ASEANSubreflion: Volume3. Section4 4. RECOMMENDED MINIMUM STANDARDS AND REQUIREMENTS FOR FUTURE TAR NETWORK As mentioned in Section 4 of Volume 2, the primary objective of this study is to recommend minimum technical standards for the future rehabilitation of the existing TAR network, and the new construction of missing links in this network. The recommendations were made in the context of achieving the required operational objectives for the TAR network so as to be more competitive with other transport modes operating in TAR corridors. Principal Railway Route Design Parameters Outline Gauge The minimum clearance is required for the transport of all types of containers including the non-ISO high-cube containers with a maximum gross weight of 35 tonnes and the maximum dimensions of2,896 mm in height, 2,591 mm in width, and 13,716-16,150 mm in length. The platform height of standard container flat wagons is normally 1,010 mm above the rail level. The vehicle gauge which is defined as the limiting dimensions, measured from the centreline of the track, beyond which any part of a vehicle or its load may not protrude, should at least accommodate the minimum clearance mentioned above. The vehicle gauge is static in nature as it implies stationary trains. For moving trains, the vehicle gauge needs to be expanded to allow for dynamic effects such as track irregularity, vehicle vibration, lateral movement of wheel, wearing of wheel, and unbalanced loads on wheels. Generally, 600-800 mm should be added to the width of the vehicle gauge, and 300-400 mm to the height.

TN 026: 2018 and TN 089: 2015 will be withdrawn with the publication of TN 005: 2019. 1. Introduction of Sub-Medium rolling stock A new rolling stock outline, to be known as Sub-Medium, will be introduced to the electrified portion of the TfNSW Metropolitan Heavy Rail Network. The Sub-Medium will comply with the Medium Electric rolling stock outline, but have what is termed a two-stage kinematic response. Operating on normal track conditions, Sub-Medium vehicles will be specified to comply with the general kinematic tolerances in Section 10.2 of ESC 215. Under certain prescribed track conditions and speed, these vehicles will be specified to generate a reduced kinematic response. Prior to the deployment of Sub-Medium rolling stock on certain sections of the network, the track width classification of those sections will be altered from Narrow to Sub-Medium or from Narrow to Medium.
