The Mitali Express (13131/13132) train is an international express rail service which connects the Indian city of Siliguri with the Bangladeshi capital Dhaka every week. Together with the Maitree Express train and the Bandhan Express train, the Mitali Express train is the third modern-day fully air conditioned passenger train link between the Indian state of West Bengal and Bangladesh. Both the prime ministers of the two neighbouring countries officially inaugurated the non-stop passenger train with ten compartments on the new 513 km route from Dhaka on 26 March 2021, the day Bangladesh celebrated the golden jubilee of its independence.
