12 Questions
What is an ideal requirement for the gauge of a permanent way?
Uniform and correct gauge
What is the width of Broad Gauge (BG) in Indian Railways?
1.676 m
When is Meter Gauge (MG) used in Indian Railways?
When funds available for the railway project are inadequate and revenue prospects are not very bright.
What material are the rails made of in a railway track?
High-carbon steel
What is the purpose of sleepers in a permanent way?
To support the rails and distribute the load evenly on the ballast.
What is the role of fasteners in a railway track?
To hold the rails firmly on the sleepers.
What is the purpose of Rails in the construction of railway tracks?
Rails provide a continuous and level surface for the movement of trains, serve as a lateral guide for the wheels, and bear the stresses developed due to vertical loads, braking, and thermal forces.
What are the three types of rails used in the construction of railway tracks?
- Double headed rails (D.H.Rails), 2. Bull headed rails (B.H.Rails), 3. Flat footed rails (F.F.Rails).
Why are longer rails considered more economical in railway track construction?
Longer rails require fewer joints and fittings, reducing the cost of construction and maintenance.
What are the two classifications of rails based on the position of sleepers?
- Supported Joints, 2. Suspended Joints.
What is the purpose of welding of rails in railway track maintenance?
Welding of rails is done to increase rail length, reduce the number of joints, and repair worn-out or damaged rails.
What is the significance of the friction between the steel wheel and the steel rail in railway operations?
The friction between the steel wheel and the steel rail is about one-fifth of the friction between a pneumatic tire and a metaled road.
