Question 1

What is the standard width of the Broad Gauge track used by Indian Railways?

Accepted Answer

1.676 meters. The correct answer is '1.676 meters'. The Broad Gauge in India measures 1676 mm between the inner faces of the rails. This gauge is the most prevalent across the Indian rail network for heavy traffic. It is significantly wider than the standard gauge used in most European countries.

Question 2

The width of the Meter Gauge track in the Indian Railway system is?

Accepted Answer

1.000 meters. The correct answer is '1.000 meters'. Meter Gauge track has a fixed width of exactly 1000 mm between the rails. Most of these tracks are currently being converted to Broad Gauge under Project Unigauge. It was widely used in hilly and less densely populated regions historically.

Question 3

Which gauge is predominantly used for Metro Rail projects in modern Indian cities?

Accepted Answer

Standard Gauge. Standard Gauge measures 1435 mm and is used by most Metro systems like Delhi and Mumbai. This gauge allows for easier procurement of international rolling stock and technology. It provides a balance between stability and urban space constraints.

Question 4

The Narrow Gauge of 0.762 meters is famously found in which of these regions?

Accepted Answer

Darjeeling Hills. Narrow Gauge tracks of 762 mm and 610 mm are typically found in mountainous areas. The Kalka-Shimla and Darjeeling Himalayan lines are famous examples of these smaller tracks. They allow trains to navigate sharper curves in difficult terrain.

Question 5

What is the primary objective of 'Project Unigauge' launched by Indian Railways?

Accepted Answer

Conversion to Broad Gauge. Project Unigauge was started in 1992 to convert various gauges into a uniform Broad Gauge. This eliminates the need for transshipment and reduces travel time for passengers and goods. It helps in creating a seamless nationwide rail connectivity.

Question 6

Which material is most commonly used for railway sleepers in modern Indian high-speed tracks?

Accepted Answer

Pre-stressed Concrete. Pre-stressed Concrete (PSC) sleepers are used due to their high durability and weight. They provide better stability for heavy and fast-moving trains compared to old wooden sleepers. These sleepers also have a much longer service life and lower maintenance costs.

Question 7

The distance between the inner faces of the two rails on a railway track is known as?

Accepted Answer

Gauge. Gauge is the technical term for the clear minimum perpendicular distance between the two rails. Different gauges are selected based on terrain, cost, and expected traffic volume. Uniformity in gauge is essential for the interchangeability of locomotives and coaches.

Question 8

Which specific track gauge is used by the Kalka-Shimla Railway, a UNESCO World Heritage site?

Accepted Answer

0.762 m. The Kalka-Shimla line utilizes the 2 feet 6 inches (762 mm) narrow gauge. This allows the track to wind through the steep Himalayan mountains with over 100 tunnels. It is an engineering marvel from the colonial era still in operation.

Question 9

In railway track terminology, what is 'Ballast'?

Accepted Answer

The gravel bed under tracks. The correct answer is 'The gravel bed under tracks'. Ballast is the layer of crushed stones placed on the railway formation upon which sleepers are laid. It holds the sleepers in place and ensures proper drainage of rainwater. It also helps in distributing the heavy load from the train to the ground.

Question 10

Which part of the railway infrastructure is responsible for changing the direction of a train from one track to another?

Accepted Answer

Points and Crossings. Points and crossings allow trains to move from one track to an adjacent one safely. They are controlled by the signaling system or manually by a lever in older systems. The precision of these components is vital for preventing derailments at junctions.
