PowerPoint Presentation: Presentation on Indian Railway Presented by- Sumeet jack . Indian Railway: Indian Railway PowerPoint Presentation: History of Indian Railway First Indian Railway line was opened on 16 th April 1853. PowerPoint Presentation: The first train consisting of one steam engine and four coaches , traversed a stretch of 21-miles between Mumbai(Bombay) and Thane. Indian Railway has a glorious past of more than150 years serving the nation. PowerPoint Presentation: Features of Indian Railway Indian Railway has a 3 tier management system. No strike in last 30 years inspite of 17 lakhs workers. It runs 12000 trains everyday. It is largest railway system in World under one management system. PowerPoint Presentation: It carries 1.4 crore passengers and 16 lakh tonnes of goods every day. PowerPoint Presentation: It is fuel efficient system. 7000 stations & about 500 computerized passenger reservation system. PowerPoint Presentation: Speed of Trains Shatabdi max 140kmph. Rajdhani max 130kmph. Others max 110kmph. PowerPoint Presentation: Railway Track or Permanent Way Combination of rails, fitted on sleepers and resting on ballast and subgrade is called the railway track or permanent way. PowerPoint Presentation: Requirements of an Ideal Permanent Way Both rails should be at the same level. Curves should be properly designed. Proper super elevation should be provided. PowerPoint Presentation: Gauge The maximum distance between the running faces of the two rails of a permanent way is called GAUGE. PowerPoint Presentation: Dimension of gauges 1-Broad Gauge(BG) 1676mm(5’6”) 2-Standard Gauge(SG) 1435mm 3-Metre Gauge(MG) 1000mm 4-Narrow Gauge(NG) 762mm(2’6”) 5-Light Gauge 610mm PowerPoint Presentation: Types of Rails 1- Double Headed Rail. 2- Bull Headed Rail. 3- Flat Footed Rail. PowerPoint Presentation: Rail Failure 1-Crushed Heads. 2-Square or Angular Breaks. 3-Split Heads. 4-Split Web. 5-Horizontal Fissures. 6-Transverse Fissure. PowerPoint Presentation: Creep of Rails Creep is defined as the longitudinal movement of the rail with respect to the sleepers PowerPoint Presentation: Defects of Creep (i) Sleepers move out of position thereby the rail gauge. (ii) Position of points and crossings are disturbed. (iii) Interlocking mechanism gets disturbed. PowerPoint Presentation: Spikes For holding the rails to the wooden Sleepers various types of spikes are used. PowerPoint Presentation: Types of spikes Dog spikes. Screw spikes. Round spikes. Standard spikes. Elastic spikes. PowerPoint Presentation: Bolts Dog or hook bolt. Fish bolts. Fang nut bolts. PowerPoint Presentation: Chairs Cast iron chair (C.I chairs). Slide chairs. PowerPoint Presentation: Sleepers Sleepers are the transverse ties that are Laid to support the rails. They transmit wheel load from the rails to the ballast. PowerPoint Presentation: Classification of sleepers Wooden sleeper Metal sleeper Cast iron sleeper Steel sleeper (iii) Concrete sleeper Reinforced concrete Sleeper (R.C.C) Prestressed Concrete Sleeper . PowerPoint Presentation: Sleeper Density Sleeper density is the number of sleepers Per rail length. It is specified as(M+x) or (N+x), where M or N is the length of the rail in meters and x is a number varies to factors . PowerPoint Presentation: Ballast Single size aggregate used in rail track construction. Generally has a nominal size of 63mm or 53mm. Can be used as a very coarse drainage material. Ballast Ballast PowerPoint Presentation: Types of ballast Sand ballast. Moorum ballast. Coal ash or cinder. Broken stone ballast. PowerPoint Presentation: Queries Please?
