What are the strengths of Indian Railways?
The following are the strengths of the Indian Railways.
- For a vast country with long distances and a large population, the Railways has an inherent advantage over other modes of transport in its suitability for movement of large volumes of passenger and goods traffic over long distances.
- The movement of steel wheels on steel rails in the railway system has the basic advantage of low rolling resistance, which reduces energy requirements and haulage costs.
- Rail transport is more efficient than road transport in terms of land use.
- Railways is an energy-efficient mode of transport, particularly for freight traffic, and can use different forms of energy. It also causes relatively less environmental pollution than road transport.
- In densely populated urban centres, a rapid transit rail-based system is the most appropriate mode of transport for suburban intra-urban travel, as part of a city’s integrated transport system.
- Indian Railways is a well-established organization with a large pool of skilled and trained personnel.
- Being part of the Central Government, Indian Railways has the government’s financial backing. At the same time, it has considerable financial autonomy.
- Indian Railways is a self-reliant system with respect to its major equipment needs.
What are the Weaknesses of Indian Railways?
The following are the weaknesses of the Indian Railways system.
- A large portion of the Railways infrastructure is overaged, and in urgent need of replacement or rehabilitation. This includes track, motive power and rolling stock, signalling, operational, and maintenance equipment.
- In certain parts of the infrastructure, the technology lags by 20-25 years behind some of the developed railway systems. Consequently, the productivity levels are comparatively low.
- Indian Railways has a large force of unskilled manpower. The training facilities need augmentation and modernization.
- A persistent resource constraint in the past has adversely affected the Railways’ development.
- Indian Railways carries a substantial ‘social burden’ in the form of continued operation of un-remunerative branch lines, subsidies on passenger and suburban travel, and even freight subsidy on certain commodities.
- In certain areas, pilferage and vandalism seriously affect operational efficiency.
- The Railways is not suited for carriage of small quantities of freight particularly over short distances.
- Heavy investments are needed to build up railway transport capacity and the gestation periods are long.
- Transport capacity is volatile and cannot be recouped if not utilized continuously.
Explain railway track.
Railway track is a combination of rails, fitted on sleepers and resting on ballast and subgrade. Essential function of railway track is to support and guide the vehicles that run over it. The conventional railway track consists of two rails located at fixed distance apart. The pressure exerted over by the rails is in turn transmitted to the formation with the help of sleepers and ballast. Railway track is also known as permanent way.
What are the basic requirements of an Ideal Permanent way?
Following are the basic requirements of an ideal permanent way:
- The gauge should be uniform and correct.
- Both the rails should be at the same level in a straight track.
- On curves, proper super-elevation should be provided to the outer rail.
- Track should have enough lateral strength.
- Track must have certain amount of elasticity
- All joints, points and crossings should be properly designed.
- Drainage system should be perfect etc.
What is gauge of railway track?
The gauges of a railway track is the clear distance between the running or gauge faces of the two rails. These running faces are the inner faces of the rails in India.
What are the different types of gauges used in India?
Broad Gauge (BG) – 1.676 m
Metre Gauge (MG) – 1.0 m
Narrow Gauge (NG) – 0.762 m
Feeder track Gauge (LG) – 0.610 m (Light Gauge)
What is coning of wheels?
The tread or rim of railway vehicles are not made flat but are sloped and this sloping aurface along the circumference forms part of a cone with a slope of about 1 in 20. This is known as coning of wheels.
What are the advantages of coning of wheels?
- On curved track, outer wheel has to travel greater length than the inner wheel. Vehicle on the curve has the tendency to moves sideways towards the outer rail, so the circumference of the tread on the outer rail towards inner edge of the wheel becomes greater than that on the inner rail. This helps outer rail to cover a greater distance than the inner rail.
- Coning of wheels reduce the wear and tear of the wheel flanges and rails, which is due to rubbing action of flanges with inside faces of the rail head.
- Because of coning of wheel, train keeps in central position in a level track.
- It provides possibility of lateral movement of axle with its wheels.
- It prevents the wheels from slipping to some extent.
What are the disadvantages of coning of wheels?
- The pressure of the horizontal component of the force near the inner edge of the rail has a tendency to wear the rail quickly.
- The horizontal component of the force tends to turn the rail outwards and hence the gauge is widened sometimes.
- If no base plates are provided, sleepers under outer edge of the rail may get damaged.
What is canting of rails or Tilting of rails?
In order to minimize the disadvantages due to coning of wheels, canting of rails is done which means that rails are not laid flat but are tilted inwards. This reduces wear on the rail as well as on the tread of the wheel. The slope of the base plate is 1 in 20 which is also the slope of the wheel flange.
What are sleepers?
Sleepers are members generally laid transverse to the rails on which the rails are supported.
What are the functions of sleepers?
Main functions of sleepers are:
- It holds the rail to correct gauge and alignment.
- It provides firms and even support to the rails
- It transfers the load in a uniform way from rails to area of ballast.
- It acts as an elastic medium between rails and the ballast to absorb the blows and vibrations of moving load.
- It provides longitudinal and lateral stability to the permanent way.
What is sleeper density?
Sleeper density is the number of sleepers per unit length. It is specified as N+x or M+x. Where N or M is the length of rails in metre or yards and x is number varying according to axle load and speed, types of rails, sleepers and ballast, ballast cushion, nature of formation etc.
What is ballast and mention its uses?
Ballast is the granular material usually broken stone or brick, shingle or kankar, gravel or sand placed and packed below and around the sleepers to tranmit load from the wheels of the train or sleepers, to formation and at the same time allowing drainage of the track.
What are points and crossing in Railway engineering?
Points, crossing and turnouts are the arrangements to divert train from one route to another.
Metro train in delhi has no ballast. What are the advantages of ballastless track?
- Long life cycles and practically no maintenance.
- Stability, precision and ride comfort.
- Irregular settlement ids less when compare to ballast tracks.
- Dust free and low structural height
- Increased service life
- High lateral track resistance which allow future speed.
Which country introduced bullet trains?
Japan introduced bullet trains. Speed of bullet trains are approximately 210 km/h.
