Railway 🚂 engineering 1

George Stephenson succeeded in running the first train of the world in

• 1825

• 1835

• 1841

• 1853

Answer explanation

In 1825 George Stephenson, built the locomotive

Locomotion No:1' for the Stockton and Darlington

Railway in the north east of England, which became the

first public steam railway in the world.

In 1829, he built the locomotive Rocket, which entered in

and won the Rainhill Trials.

The first Locomotive Rocket was from Liverpool and

Manchester Railway, built in 1830.

Answer explanation

COMPOSITE SLEEPER INDEX (C.S.I) is an index to

determine the suitability of a particular timber for use as

a sleeper. It measures the mechanical strength of a

timber. Timber quality test is done by Forest Research

Institute whose Headquarter is at Dehradun, India.

First electric railway in India started functioning from

• 1925

• 1825

• 1853

• 1952

Answer explanation

The first electric train ran in India with the inauguration

of services between Bombay VT and Kurla Harbour on

3rd Feb 1925 on ex-GIP Railway system. The section was

electrifed on 1500 Volt DC.

The first railway train in India ran between

• Mumbai and Thane

• Chennai and Bangaluru

• Calcutta and Delhi

• Howrah and Dadar

Answer explanation

The first passenger train in India ran between Bombay

(Bori Bunder) and Thane on 16 April 1853. The 14-

carriage train was hauled by three steam locomotives:

Sahib, Sindh and Sultan. It carried 400 people and ran on

a line of 34 kilometers (21 mi) built and operated by

GIPR. It was built in 1,676 mm(5 ft 6 in) broad gauge,

which became the country's standard for railways.

In railways, Tender is a component of

• Rolling stock

• Permanent way

• Plate laying

• None of these

Answer explanation

Rolling Stock is the vehicle that move on railway track. Its

components include

o Locomotive/engine,

Coaches- for passenger accommodation,

oWagons- for transportation of goods

o Tender-small bogie next to engine to store fuels

Charles Vignole invented.type of rail sections

• Double headed rails

• Bull headed rails

• Flat footed rails

• None of these

Answer explanation

Charles Vignoles invented flat footed rails in 1836.

This rails are also called as Vignoles rails.

It is the most commonly used in Indian railway.

The rail section first designed in Indian railway was

• Double headed rail

• Bull headed rail

• Flat footed rail

• None of these

Answer explanation

First designed is Doubled headed rail, then Bull headed

rails and lastly flat footed rails. Double headed rails are

Modern track typically uses with a profile of an asymmetrical rounded -beam.

• wooden

• hot-rolled steel

• iron

• alloy of aluminium

Answer explanation

Unlike some other uses of iron and steel, railway rails are

subject to very high stresses and have to be made of very

high-quality steel alloy. It took many decades to improve

the quality of the materials, including the change from

iron to steel. The stronger the rails and the rest of the

track work, the heavier and faster the trains the track can

carry.

The tensile strength of the rail should not be

• more than 72 kg/mm

• less than 100 kg/mm

• less than 706 MPa

• more than 98.8 MPa

Answer explanation

The tensile strength of the rail should not be less than 72

kg/mm* 706 MPa

Which of the following is not a function of rails?

• Serving as a lateral guide

• To provide drainage

• Providing a continuous surface

• To provide a level surface

Answer explanation

function of rails:

Serving as a lateral guide

Providing a continuous surface

To provide a level surface

bears stresses due to vertical loads, lateral force,

braking loads
