The factors that influence train resistance are summarized as the journal-bearing friction, track resistance to rolling, wind resistance, curve and grade resistances, acceleration resistance, and starting resistance. Each of these factors is examined for its magnitude of contribution to total train resistance.
What is train resistance?
Train resistance, the force required to move a train, is the sum of the rolling resistance on tangent level track, grade resistance and curve resistance of the locomotives and cars.
How many types of trains are there?
Indian Railways: 29 Types of Trains. Indian Railways is one of the most popular and busiest modes of transportation in India and connects numerous cities, towns, states, districts, and regions.
How is train resistance calculated?
Train resistance is calculated by multiplying the resistance per ton at each speed, by the total tonnage of the train.
Are there different trains?
There are three main types of passenger trains: long-distance, short-distance, and trains within cities.
What are the different types of train resistance?
The factors that influence train resistance are summarized as the journal-bearing friction, track resistance to rolling, wind resistance, curve and grade resistances, acceleration resistance, and starting resistance. Each of these factors is examined for its magnitude of contribution to total train resistance.
What is train shunt resistance?
The highest resistance which, when applied across the track, can open the track relay front contacts is known as its ‘Train Shunt Resistance’ (TSR) value. It is the measure of its dependability. Rfc. Resistance of track lead cable at feed end.

What are the different types of sleepers used in Indian Railways explain each in detail?
The sleepers mostly used on Indian Railways are (i) wooden sleepers, (ii) cast iron (CI) sleepers, (ii) steel sleepers, and (iv) concrete sleepers.
What is hauling capacity in railway?
Hauling power = number of pairs of driving wheels x weight exerted on the driving wheels x coefficient of friction Thus, for a locomotive with three pairs of driving wheels, an axle load of 20 t, and a coefficient of friction equal to 0.2, the hauling power will be equal to 3 x 20 x 0.2 t, i.e., 12 t.
Which train resistance is proportional to square of speed?
u=V0cosα.
What are electric trains called?
electric locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor.
What is the longest train in the world?
The Trans–Siberian Railway which connects Moscow with the Russian far east is still the world’s longest direct rail route, running for 9,259 kilometers or 5,753 miles.
Who invented trains?
Officially, trains were invented when Englishmen Richard Trevithick and Andrew Vivian received a patent for the world’s first steam locomotive in 1802. The little unnamed machine was placed into service on the Penydarren Ironworks’ tramway in Merthyr Tydfil, Wales on February 21, 1804.
What is tractive force railway?
In railway engineering, the term tractive effort is often used synonymously with tractive force to describe the pulling or pushing capability of a locomotive.
How do you find the resistance of a gradient?
Gradient resistance is given by Gr = W sin(angle of inclination).
What is meant by the term adhesive weight?
Adhesive weight is the weight on the driving wheels of a locomotive, which determines the frictional grip between wheels and rail, and hence the drawbar pull which a locomotive can exert.
What is QBAT relay?
∎ QBAT relay. • This relay has a A.C. immunity level of 80 Volt A.C. • This is achieved by the provision of a biasing. permanent magnet on its core along with its copper slug.
What is fouling mark in railways?
‘fouling mark’ means the mark, at which the infringement of. fixed Standard Dimensions occurs, where two lines cross or join. one another; (24) ‘Gangman’ means a railway servant employed on permanent.
