Running through the densely populated urban areas railway has an inherent weakness of generating congestions at the at-grade crossings or level crossings (LC). It is responsible for economic losses, emission of harmful gases, and increase in accident risks for roadway traffic. Realizing these effects many of the developed countries have adopted various solutions starting from automatic gates installation to grade separation. However, developing countries have either failed to address the congestion problems caused by LCs, or yet to adopt appropriate measures to counteract them. Dhaka, the most densely populated megacity of the world has 42 level crossings in the city. This study reveals the economic losses, environmental impact and safety hazard of the busiest 7.15 kilometer railway corridor which has six level crossings. Primary field data have been utilized to find the delays and emission incurred by individual LC using available methods with slight modifications. Yearly economic losses incurred by studied LCs are estimated to be 32.95 million USD.
