Railway Gauge Railway Gauge Presentation Transcript

  • TECH PRESENTATION Topic :- RAIL GAUGES Presented by :- Amit Yadav & Prateek Singh Civil Engg. 4th Sem L.I.S.T. Bhopal 1
  • RAILWAY ENGINEERING The branch of Civil Engineering which deals with the design, construction and maintenance of the railway tracks for safe and efficient movements of trains is called Railway 2

  • SCOPE OF RAILWAY ENGINEERING Apart from design, construction and maintenance of tracks, Railway engineering also includes the study of the following important topics :Types of surveys necessary in marking the alignment of different railways tracks. Materials required in the construction of railway tracks. Track geometrics. Points and crossings. Railways stations and yards. Signaling and interlocking, etc. 4 View slide
  • PERMANENT WAY Permanent way is a track which is permanent in nature which handles the normal commercial traffic. 5
  • The following are the component parts of a permanent way or a railway track :-      Formation or sub grade ; Ballast ; Sleepers ; Rails ; Fixtures and fastenings. 6
  • The following are the principal requirements of an ideal permanent way or of a good railway track :- i. The gauge of the permanent way should be uniform, correct and it should not get altered. ii. Both the rails should be at the same level on tangent (straight) portion of the track. iii. Proper amount of *super elevation should be provided to the outer rail above the inner rail on curved portion of the track. 7
  • GAUGE The clear horizontal distance between the inner (running) faces of the two rails forming a track is known as Gauge. (see in fig given below) This gauge of 1435 mm has been universally used in Great Britain, France, Germany, U.S.A., Canada and most other countries of Europe and is thus known as the world standard gauge. In India broad gauge used which has standard size 1676 mm. 8

  • TYPES OF GAUGES PREVALENT IN INDIA The different gauges prevalent in India are of the following these types :1. Broad gauge (1676), 2. Metre gauge (1000), 3. Narrow gauge (762 mm & 610 mm). 10
  • 1. Broad Gauge :- When the clear horizontal distance between the inner faces of two parallel rails forming a track is 1676mm the gauge is called Broad Gauge (B.G) This gauge is also known as standard gauge of India and is the broadest gauge of the world. The Other countries using the Broad Gauge are Pakistan, Bangladesh, SriLanka, Brazil, Argentine,etc.50% India’s railway tracks have been laid to this gauge. 11
  • Suitability for Broad Gauge: Broad gauge is suitable under the following Conditions :(i) When sufficient funds are available for the railway project. (ii) When the prospects of revenue are very bright. This gauge is, therefore, used for tracks in plain areas which are densely populated i.e. for routes of maximum traffic, intensities and at places which are centers of industry and commerce. 12
  • METRE GAUGE  When the clear horizontal distance between the inner faces of twoparallel rails forming a track is 1000mm, the gauge is known as Metre Gauge (M.G) The other countries using Metre gauge are France, Switzerland, Argentine, etc. 40% of India’s railway tracks have been laid to this gauge. 13
  • Suitability for Metre Gauge: :- Metre Gauge is suitable under the following conditions:(i) When the funds available for the railway project are inadequate. (ii) When the prospects of revenue are not very bright. . 14
  • NARROW GAUGE: when the clear horizontal distance between the inner faces of two parallel rails forming a track is either 762mm or 610mm, the gauge is known as narrow gauge (n.g) the other countries using narrow gauge are britain, south africa, etc. 10% of india’s railway tracks have been laid to this gauge. 15
  • Suitability for Narrow Gauge: Narrow gauge is suitable under the following conditions :( i) When the construction of a track with wider gauge is prohibited due to the provision of sharp curves, steep gradients, narrow bridges and tunnels etc. (ii) This gauge is, therefore, used in hilly and very thinly populated areas. The feeder gauge is commonly used for feeding raw materials to big government manufacturing concerns as well as to private factories such as steel plants, oil refineries, sugar factories, etc. 16
  • 1. Advantages of Breaking the Gauge :i). The most effective advantage of breaking the gauge is to render the railway an economical and profitable concern. ii). It facilitates the provision of a steeper gradient, sharp curves and narrow tunnels by adopting a less wide gauge in hilly and rocky areas. 17
