  1. 1. Presented by- Khusro Khan.
  2. 2. Indian Railway
  3. 3. History of Indian Railway First Indian Railway line was opened on 16th April 1853.
  4. 4. The first train consisting of onesteam engine and four coaches ,traversed a stretch of 21-milesbetween Mumbai(Bombay) andThane.Indian Railway has a gloriouspast of more than150 yearsserving the nation.
  5. 5. Features of Indian RailwayIndian Railway has a 3 tiermanagement system.No strike in last 30 years inspite of17 lakhs workers.It runs 12000 trains everyday.It is largest railway system in Worldunder one management system.
  6. 6. It carries 1.4 crore passengers and 16lakh tonnes of goods every day.
  7. 7. It is fuel efficient system.7000 stations & about 500computerized passenger reservationsystem.
  8. 8. Speed of TrainsShatabdi max 140kmph.Rajdhani max 130kmph.Others max 110kmph.
  9. 9. Railway Track orCombination of rails, fittedWay Permanent subgrade is on sleepersand resting on ballast andcalled the railway track or permanentway.
  10. 10. Requirements of anIdeal Permanent WayBoth rails should be at the same level.Curves should be properly designed.Proper super elevation should beprovided.
  11. 11. GaugeThe maximum distance between therunning faces of the two rails of apermanent way is called GAUGE.
  12. 12. Dimension of gauges1-Broad Gauge(BG) 1676mm(5’6”)2-Standard Gauge(SG) 1435mm3-Metre Gauge(MG) 1000mm4-Narrow Gauge(NG) 762mm(2’6”)5-Light Gauge 610mm
  13. 13. Types of Rails1- Double Headed Rail.2- Bull Headed Rail.3- Flat Footed Rail.
  14. 14. Rail Failure1-Crushed Heads.2-Square or Angular Breaks.3-Split Heads.4-Split Web.5-Horizontal Fissures.6-Transverse Fissure.
  15. 15. Creep of RailsCreep is defined as thelongitudinal movement of the railwith respect to the sleepers
  16. 16. Defects of Creep(i) Sleepers move out of position thereby the rail gauge.(ii) Position of points and crossings aredisturbed.(iii) Interlocking mechanism getsdisturbed.
  17. 17. SpikesFor holding the rails to the woodenSleepers various types of spikes are used.
  18. 18. Types of spikesDog spikes.Screw spikes.Round spikes.Standard spikes.Elastic spikes.
  19. 19. Bolts(i) Dog or hook bolt.(ii) Fish bolts.(iii) Fang nut bolts.
  20. 20. Chairs(i) Cast iron chair (C.I chairs).(ii) Slide chairs.
  21. 21. SleepersSleepers are the transverse ties that areLaid to support the rails.They transmit wheel load from the railsto the ballast.
  22. 22. Classification of sleepers (i) Wooden sleeper Cast iron sleeper (ii) Metal sleeper Steel sleeper Reinforced concrete Sleeper (R.C.C) (iii) Concrete sleeper Prestressed Concrete Sleeper .
  23. 23. Sleeper DensitySleeper density is the numberof sleepers Per rail length. Itis specified as(M+x) or(N+x), where M or N is thelength of the rail in metersand x is a number varies tofactors .
  24. 24. BallastSingle size aggregate used in rail trackconstruction. Generally has a nominal size of63mm or 53mm. Can be used as a very coarsedrainage material. Ballast Ballast
  25. 25. Types of ballast Sand ballast. Moorum ballast. Coal ash or cinder. Broken stone ballast.
