Last month I traveled from Kanpur to Delhi by Unchahar Express. Train was running late by 1 hour. I generally never sleep at night while I travel. When the train crossed Aligarh, I noticed that the speed of train was too high and the coach was vibrating too much, I mean more than normal, and I guess the speed of the train was 110 km/h or above. It was a conventional coach and I thought that these coaches are not fit for high speed run. I was scared so much that I started praying for safe journey and prayed till I reached my destination.
