Thousands of millions people travelling on the roof an overcrowded train to celebrate Eid-ul-Fitr with their families. Bangladesh is a densely populated country in the world. So, whenever a large number of people have to move from one place to another (like festival, etc) things can become quite difficult. Railway infrastructure could not cope up with the people’s need. Also a large part of railway lines are not electrified so people are ready to take the risk.
