Conclusion
Train problems become easier when you remember that speed should usually be converted into metres per second, the train’s own length is used when crossing a pole, and the train’s length plus the platform or bridge length is used when crossing a fixed object. For two moving trains or a moving person, use relative speed. Regular practice of these 100 Train Questions can improve your speed and accuracy in SSC, Railway, Banking, Police, Defence, and other competitive examinations.
