Problems on Trains - Aptitude Questions, Shortcuts, Formulas

We cover all the topics and concepts of Aptitude Problems on trains like two trains are moving in opposite directions, calculate train speed, calculate distance, etc.

Rules on Problem On Trains

Rule 1: When two trains are moving in opposite directions, then relative speed will be the addition of their individual speeds.

Rule 2: When two trains are moving in same direction, then relative speed will be the subtraction of their individual speeds.

Rule 3: On passing a platform by a certain train the net distance traveled is the sum of length of train and the length of platform both.

Rule 4: When a train passes through a pole or person standing, net distance traveled to pass is the length of the train

 

Problems on Trains Formulas

  • x km/hr = x \times \frac{5}{18} m/s
  • y m/s = y\times \frac{18}{5} Km/hr
  • Speed = distance/time
  • Velocity = displacement/time
  • Time taken by a train x meters long to pass a pole or standing man or a post = Time taken by the train to travel x meters.
  • Time taken by a train x meters long to pass an object of length y meters = Time taken by the train to travel (x + y) metres.
  • Suppose two trains or two objects are moving in the same direction at v1 m/s and v2 m/s where v 1 > v 2, then their relative speed = (v 1 v 2) m/s
  • Suppose two trains or two objects are moving in opposite directions at v 1 m/s and v 2 m/s , then their relative speed = (v 1+ v 2) m/s
  • Assume two trains of length x metres and y metres are moving in opposite directions at v 1 m/s and v 2 m/s, Then the time taken by the trains to cross each other = (x+y) / (v 1+v 2) seconds
  • Assume two trains of length x metres and y metres are moving in the same direction at at v 1 m/s and v 2 m/s where v 1 > v 2, Then The time taken by the faster train to cross the slower train = (x+y) / (v 1-v 2) seconds.
  • Assume that two trains (objects) start from two points P and Q towards each other at the same time and after crossing they take p and q seconds to reach Q and P respectively. Then, A's speed: B's speed = \sqrt{q} : \sqrt{p}
