We all have sat in trains, haven't we? Are you ready for a railway engineering MCQ quiz? Railway engineering is known as a multi-faceted engineering discipline that deals with the design, construction as well as operation of all types of rail transport systems. Whenever we look at the railway system, we are amazed by its huge construction. No worries. Today, this quiz will give you some insight into railway engineering. All the best.

### How much is one degree of curve equivalent to?

• A.

1250/R

• B.

1750/R

• C.

1950/R

• D.

2150/R

B. 1750/R
Explanation
One degree of curve is equivalent to 1750/R. This means that for every degree of curve, the radius of the curve is divided by 1750. The value of R determines the size of the curve, with larger values of R indicating a more gradual curve and smaller values indicating a sharper curve. Therefore, the correct answer implies that the degree of curve is inversely proportional to the radius of the curve.

### Which of these is a type of gauge in Indian railway?

• A.

• B.

Meter gauge

• C.

Two narrow gauges

• D.

All of these

D. All of these
Explanation
All of these options are types of gauges in the Indian railway system. Broad gauge refers to a wider track width, meter gauge refers to a narrower track width, and two narrow gauges refer to two different narrower track widths. Therefore, all of these options are correct types of gauges in the Indian railway.

### What are the standard dimensions of a wooden sleeper that is for a B.G. railway track?

• A.

2.74 m Ã— 25 cm Ã— 13 cm

• B.

4.74 m Ã— 35 cm Ã— 13 cm

• C.

1.74 m Ã— 15 cm Ã— 13 cm

• D.

1.74 m Ã— 25 cm Ã— 18 cm

A. 2.74 m Ã— 25 cm Ã— 13 cm
Explanation
The correct answer is 2.74 m Ã— 25 cm Ã— 13 cm. This dimension is the standard size for a wooden sleeper used in a Broad Gauge (B.G.) railway track. The length of 2.74 m ensures that the sleeper can provide adequate support for the tracks. The width of 25 cm and height of 13 cm are designed to fit the track and provide stability.

### Which of these is a component of the rail?

• A.

Foot

• B.

Web

• C.

Both A & B

• D.

None of these

C. Both A & B
Explanation
Both the foot and the web are components of a rail. The foot is the bottom part of the rail that rests on the track bed, providing stability and support. The web is the vertical section of the rail that connects the foot to the head, which is the top part of the rail. The web helps to distribute the weight and forces exerted on the rail, ensuring its structural integrity. Therefore, both the foot and the web are essential components of a rail.

### For Broad Gauge, what is the limiting value of cant excess?

• A.

75 mm

• B.

82 mm

• C.

91 mm

• D.

95 mm

A. 75 mm
Explanation
The limiting value of cant excess for Broad Gauge is 75 mm. Cant excess refers to the difference in height between the inner and outer rails of a curved track. It is necessary to have a certain amount of cant excess to ensure stability and prevent derailments. However, exceeding the limiting value can lead to operational issues and safety concerns. Therefore, in the case of Broad Gauge, the maximum allowable cant excess is 75 mm.

### If the degree of the curve does not exceed ________, pot sleepers are used.

• A.

2 degree

• B.

4 degree

• C.

6 degree

• D.

8 degree

B. 4 degree
Explanation
If the degree of the curve does not exceed 4, pot sleepers are used. This means that if the curve is not too sharp, pot sleepers, which are specially designed to accommodate curves, can be used. Pot sleepers are used to provide stability and support to the tracks on curved sections, ensuring safe and smooth train operations.

### Which is the largest dimension of a rail?

• A.

Its foot width

• B.

• C.

Its weight

• D.

Its height

D. Its height
Explanation
The largest dimension of a rail is its height. This refers to the vertical measurement of the rail, from the bottom of the foot to the top of the rail. The height of a rail is an important factor in determining its strength and stability, as well as its ability to support the weight of trains and withstand the forces exerted on it.

### By what are rails fixed on steel sleepers?

• A.

By dog spikes

• B.

By bearing plates

• C.

Both A & B

• D.

By keys in lugs or jaws

D. By keys in lugs or jaws
Explanation
The rails are fixed on steel sleepers by keys in lugs or jaws. This method involves inserting keys into the lugs or jaws of the rail and the sleeper, securing them together. This ensures that the rails are firmly fixed in place and prevents them from moving or shifting. Dog spikes and bearing plates are not used in this particular method of fixing rails on steel sleepers.

### What is the gradient called, on which another additional engine is needed to negotiate the gradient?

• A.

• B.

• C.

• D.

None of these

Explanation
The pusher gradient refers to a gradient on a railway track where an additional engine is required to assist the train in climbing the steep slope. This additional engine, known as a pusher, helps to provide the necessary power and traction to overcome the gradient. Therefore, the pusher gradient is the correct answer as it specifically mentions the need for an additional engine to negotiate the gradient.

### For the prevention of what, burnettizing is done?

• A.

Rails

• B.

Ballast

• C.

Wooden sleepers

• D.

None of these

C. Wooden sleepers
Explanation
Burnettizing is a process of treating wood with a chemical preservative to protect it from decay and insect damage. Wooden sleepers are commonly used in railway tracks to support the rails. By burnettizing the wooden sleepers, they become more resistant to rot and insect infestation, thereby increasing their lifespan and preventing the need for frequent replacements. Therefore, burnettizing is done for the prevention of decay and insect damage in wooden sleepers.
