About Problems on Trains MCQs
Train problems are a special case of time, speed and distance. The key idea is that a train must cover its own length to pass a pole or person, and its own length plus the length of a platform, bridge or another train to pass that object. Questions on this page include finding train length from speed and time, using relative speed for trains moving in the same or opposite directions, and a jogger running ahead of an engine. Converting km/h to m/s by multiplying by 5/18 is needed in almost every question.

Frequently asked questions
What is the formula for a train crossing a platform?
Time taken equals the sum of the train's length and the platform's length divided by the train's speed. For example, a 240 m train passing a pole in 24 seconds moves at 10 m/s, so passing a 650 m platform takes 890 divided by 10, which is 89 seconds.
How is relative speed used in train problems?
When two trains move in opposite directions, add their speeds to get the relative speed. When they move in the same direction, subtract the smaller speed from the larger. The distance to cover is the sum of both train lengths, and time equals that distance divided by the relative speed.
