Train running status feature enables passenger to know the live delay information of trains as per the NTES data. This feature is very important because sometimes trains are as late as 12 hours. During winter a lot of trains run late in northern India due to dense fog. Trainman also tells the intermediate stations between all pair of stopping stations with distance and expected crossing time, therefore it becomes really easy for user to pinpoint the current train location. For stations where train is yet to arrive one can know the expected arrival time considering the current delay. Further passenger can enquire about cancelled and diverted trains on Trainman running status page.
