The problem on trains are important chapter for easily get the marks in competitive exam papers. you just remember the way of train cross the object and speed, time and distance. There are train based problem based on two object, Here we learn the problem on time taken by train pass a pole, a man or light lamp.

First is Train and second object is that which is crossed by the train. This is the basic theory of train which is applied in question to obtain answers here train Methods of example in different form of examples.
In maths exam papers there are two or three question are given from this chapter. This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam. Under below given some more example for your better practice.



Example 1: A train 480 meter long running at the speed of 54 km/hr. In what time will it pass a bridge 120 meter long ?
Answer : Total distance covered = (480 + 120)meter = 600 meter.
Speed = (54 x 5 / 18) = 15 m/sec
Required time = (600 / 15)sec = 40 sec.



Example 2: Two local train are 220 meter and 180 meter length respectively. The trains are running at the speed of 35 km/hr and 55 km/hr in the same direction. What time would be taken to cross the first train ?
Answer :
Shortcut : Time = 400 x 18 / (55 – 35) x 5 = 72 sec.
72 sec = 1 min 12 sec.



Example 3:
In what time will a 350 meter long train running at the speed of 90 km / hr cross a pole ?
Answer :
Speed = 90 x 5 / 18 = 25 m / s.
Time = 350 / 25 = 14 seconds.



Example 4:
A Rajdhani Express train 160 m long and running at speed  72 Km / h. It crosses a platform  which is 240 m long. How much time will it cross a platform.
At First we add the length of train and platform is 160 m + 240 m = 400 m, and convert the speed into m / sec that is ( 72 x 5 ) / 18 = 20 m / sec.
Required time to cross a platform is T = D / S, = 400 / 20 = 20 sec.
Note: Here is we add the length of train and platform both because we can’t ignore the length of platform.



Example 5:
A Mail train 250 meters long passes a standing boy in 5 seconds. How long will it take to cross a bridge 500 meters long ?
Answer :
Train length = 250 meters.
( 250 / 5 ) m / sec = 50 m / sec.
Time taken to cross its own length is 50 m /sec.
Time taken to cross the bridge = ( 500 + 250 / 50 ) m / sec = 750 / 50 = 15 m / sec.



Example 6:
A super fast train 150 m long is running at the speed 90 Km / hr. Find the time taken by it to pass a boy standing  near the railway track.
First we convert the speed of super fast train Km / hr to m / sec multiplying by 5 / 18.
So, ( 90 x 5 / 18 ) m / sec = 25 m / sec. so speed of train is 25 m / sec.
The super fast train passing a standing boy near the railway track = 150 m.
Formula: Time =  Distance / Speed.
So, The time taken to cross the standing boy is T = D / S = ( 150 / 25 ) sec = 6 sec.
Note: Here width of boy,  light lamp, pole, tree etc are  in length.



Example 7: A local train running at a speed of 54 km/hr, to cross a pole in 20 seconds. What time will it take to crossing a 300 meter long bridge?
Answer : Speed convert to km/hr to m/sec
54 x 5 / 18 = 15 m/sec.
So, length of train = 20 x 15 = 300 sec.
we add length of train and length of bridge 300 + 300 = 600
T = D / S = 600 / 15 = 40 seconds.
So, it would cross bridge in 40 seconds.
