Question

What number of kinds of railway engines are there?
A)- 2
B)- 3
C)- 4
D)- 5

Answer 1

Hint:A locomotive or engine is a rail shipping car that gives the purpose electricity for a teach. If a locomotive is capable of wearing a payload, it's also alternatively known as a more than one unit, motor educate, railcar or energy automobile; using those self-propelled automobiles is increasingly more common for passenger trains, but uncommon for freight (see CargoSprinter and Iron motorway).

Complete answer:
There are 3 styles of railway engine: mechanical, hydraulic or electric powered. Most diesel locomotives use electric powered transmission and are called "diesel-electric" locomotives. Mechanical and hydraulic transmissions are nonetheless used however are greater commonplace on more than one unit trains or lighter locomotives.

There are three techniques of doing this: mechanical, hydraulic or electric powered. Maximum diesel locomotives use electric powered transmission and are referred to as "diesel-electric powered" locomotives. Mechanical and hydraulic transmissions are still used however are extra not unusual on multiple unit trains or lighter locomotives. In line with the specifications furnished via the Railways, those locomotives are nation of art IGBT primarily based, three phase pressure, 9000 KW (12000 horsepower) electric powered locomotive.
Traditionally, locomotives pulled trains from the front. However, push-pull operation has ended up not unusual, in which the educator may additionally have a locomotive (or locomotives) on the front, at the rear, or at every stop. Most lately railroads have begun adopting DPU or distributed energy. The front can also have one or locomotives accompanied by a way of a mid-educated locomotive that is controlled remotely from the lead unit.

Hence the correct answer is option B.

Note:Country-owned Chittaranjan Locomotive Works (CLW) has given the Indian Railways its fastest ever engine. The changed WAP five, which is yet to have a call, is expected toTravel at 200 kmph. In a diesel–electric locomotive, the diesel engine drives either an electrical DC generator (commonly, less than 3,000 horsepower (2,200 kW) net for traction).
