  1. INTEGRATED RAILWAY MODERNISATION PLAN (IRMP)(2005-2010)

  2. AN OVERVIEW OF IR • IR is third largest railway system in the world under a single management having 63000 route km, handling 14 million passengers/day & 1.8 MT freight/day. • Volume of traffic moved & its relatively low cost to common man makes IR the prime mover of the nation.

  3. With national GDP growth targeted around 8% as per Xth plan document, the growth in freight & passenger traffic on IR is likely to be substantial. Taking into a/c ambitious growth rate of over 6% in freight traffic (against 5.6% expected) and 3.5% in passenger traffic (against 3.1%), IR would be handling 776 million tonnes and carry 6366 million originating passengers. Still not a world class railway system.

  4. IR has to embark upon a path of modernization and expansion in a big way, as per the vision of the PM. • Integrated Railway Modernisation Plan (2005-10) has been made which has objective to enhance capacity, improve rail-port connectivity, higher axle load wagons to carry bulk material and development of dedicated freight corridors. Two inter city

  5. corridors Delhi-Patna-Howrah and Delhi Chennai to be developed to run 150 kmph trains using latest technology high speed coaches and running of freight trains @ 100 kmph on the high density Golden Quadrilateral and its Diagonals connecting the four metropolitan cities. IR also plans to develop a world class high speed dedicated passenger corridor fit for 250-300 kmph trains. Ahmedabad-Mumbai has been identified for feasibility studies as a part of separate project.

  6. Total cost of plan is Rs.24000 crores out of which Rs.10000 crores through additional budgetary support, 4000 crores from Special Railway Safety Fund (SRSF), 4000 crores from internal resources and 6000 crores from market borrowing. • It has various components covering passenger Business Segment costing Rs.5740 crores and Freight Business segment costing Rs.5210 crores.

  7. The modernization initiatives other than those relating to above are primarily in the infrastructure to support business objectives of the organization. These include modernization of fixed infrastructure such as track, bridges, signal & telecom, rolling stock, safety, training and other I.T. based system which will cost about Rs.13000 crores.

  8. 1.0 TRACK MODERNISATION 1.1Laying of track with modern track structure having heavier 52/60 kg Rails with higher Ultimate Tensile Strength (UTS) of 90 kg/mm2 and low hydrogen content (1.6 ppm), PRC Sleepers and modern elastic fastenings. Timely renewal of track helps to improve safety of train operation and improves throughput. Modern track structure is to be adopted while clearing the arrears as per norms and consistent with traffic requirements. On bridges, composite sleepers are to be laid in lieu of wooden sleepers.

  9. 1.2 Long rails and their transportation by modern techniques.Indian Railways has entered into a memorandum of understanding with SAIL to produce 65 metres long rails which will be welded in Bhilai Steel Plant, to make a rail panel of 260 metres length. These long rail panels will be directly transported to the site, thereby, reducing the number of welds. Production of 65 metre long rails has already started while 260 metre long rail panels are expected by 2005-06. For transportation of these long rails, 5 mechanized rakes are required to be procured. Trials for running these rakes are expected by 2006-07.

  10. 1.3 Adoption of modern Self Propelled Ultrasonic Rail Testing (SPURT) Car. The ultrasonic testing of rails, laid in the track is being done manually which is a slow, strenuous, time consuming process and largely depends on human judgment. It is planned to get the testing done through SPURT cars which shall be faster as well as more reliable. It is targeted to procure 5 SPURT cars by 2006-07.

  11. 1.4 Mechanisation of Track Maintenance and relaying activity The state-of-the-art high output track machines are being procured on Indian Railways and the level of mechanisation of track renewal and maintenance activities is being increased. The objective is to achieve the desired track geometry, enhance the safety environment at worksites, fewer speed restrictions better quality, reduced manpower and faster execution of work. …contd…

  12. This will reduce the requirement of corridor block from present 4 hrs to 2 hrs and also facilitate maintenance of track, etc, during night time. The track machines are being sanctioned through various Rolling Stock Programme (RSP) and it has been planned to achieve full mechanisation of track maintenance and relaying activities by 2012.

  13. 1.5 Introduction of Mobile Maintenance Units (MMU) for track maintenance The objective of introduction of MMU is to mechanise the day-to-day track maintenance activities for better quality and safety with reduced manpower. The pilot project for implementation of MMU is in advanced stage on Allahabad and Kota Divisions on Indian Railways. Following successful trials and tests, the entire Group ‘A’ route on Indian Railways is to be covered in phases.

  14. 1.6Mobile Flash Butt Welding The population of Alumino Thermit (AT) weld is to be gradually reduced and replaced by Flash Butt (FB) welds, which will improve quality of welds and enhance safety. On new construction projects, there are logistical problems in transporting long rails and, therefore, small rail lengths are transported and welded at site. It is proposed to use mobile flash butt welding in construction projects from year 2004 and gradually extend it to other areas in next five years. About 90% of the total welding, in Construction projects, is targeted with Mobile Flash Butt Welding in next 5 years.

  15. . 1.7 Adoption of Modern Improved Turn-outs with Thick Web Switches (TWS) and weldable Cast Manganese Steel (CMS) crossings It has been established through trials that Thick Web Switches (TWS) are more stable and require lesser maintenance. Adoption of TWS is expected to improve life cycle cost as well as safety standards. On first priority, it has been planned to provide TWS on entire group ‘A’ route and other high density routes with annual traffic more than 20 GMT. A total of 10,000 nos. are to be laid in 5 year period. ….contd.

  16. It is further planned to provide weldabe Cast Manganese Steel (CMS) crossings as a part of improved turnouts to facilitate the continuation of Long Welded Rails (LWR) through turnouts, thus reducing a large number of fish plated joints and improving the level of safety as fish plated joints are sabotage prone. As a first step, 2000 nos. of TWS will be procured per year for replacement purpose starting from 2006-07.

  17. 1.8 Safety on long welded rails by adoption of modern stress measuring methods The safety of Long Welded Rail (LWR) track is vitally affected by locked up thermal stresses, which play an important role in the phenomenon of buckling or fractures and, thus, have important bearing on safety. It is planned to deploy stress measuring equipment whether developed indigenously or use those already developed and available on other world Railways. This will help reduce maintenance effort, fractures and enhance safety. Trials are proposed to be completed by 31.3.2005.

  18. 1.9 Preventive Rail Grinding Rails with 90 Ultimate Tensile Strength(UTS) have higher hardness and a tendency of developing gauge corner cracks due to Rolling Contact Fatigue (RCF). This can be prevented by rail grinding to remove the top layer of rail metal. Many World Railways have increasingly adopted this method. This is expected to increase rail life, reduce fractures, reduce cost and improve safety. Procurement of a rail grinding machine is, therefore, planned.

  19. 1.10 Inspection and Track Monitoring by Modern Equipments Track Recording Cars (TRCs) are run on all BG routes of Indian Railways at a specified frequency. These record the parameter and oscillation characteristics of the track for planning the maintenance needs of track. There are 5 TRCs available on Indian Railways which are being upgraded and one new TRC is under commissioning.

  20. 2.0BRIDGE MODERNISATION 2.1 Modern Comprehensive Bridge Management System for Indian Railways We propose to introduce a Bridge Management System (BMS) as a pilot project over South Eastern Railway followed by full scale adoption over Indian Railway System in next five years. This computerised system will facilitate quick retrieval and analysis of data, optimum resource allocations, network & project level management, planning based on “deteriorating models for bridges”. The BMS will be web based to facilitate entry and access of data at field as well as at head quarters level.Pilot project will be completed by 31.03.2008.

  21. 2.2 Modernisation of Inspection Techniques and adoption of developed techniques for Bridges over Indian RailwaysSeveral measures for modernizing the inspection, monitoring and health assessment of railway bridges with a view to ensuring safety and providing intervention in a need based manner have been initiated. Pilot projects in the following areas have been sanctioned. 2.2.1 Adoption of State-of-Art Non Destructive Testing (NDT) equipments.

  22. 2.2.2 Mapping of unknown foundations and integrity testing of foundations 2.2.3. Acoustic Emission Testing of bridges 2.2.4 Fatigue testing and remaining life assessment of Steel Bridges 2.2.5 Strain gauging and load rating of bridges 2.2.6 Use of Mobile rail cum road Bridge Testing Laboratories 2.2.7 In situ Dynamic Testing – Indo – Austrian Programme

  23. 2.3 It is now proposed to undertake studies and develop projects in the following areas. 2.3.1 Testing and Remote Monitoring of bridges using modern technologies – IIT/Mumbai. a. Vibration Signature Testing and b. Remote Monitoring of Bridges 2.3.2 Adopting Seismic Isolation Techniques & Earthquake Protection of Bridges in collaboration with IIT/Kanpur.
