The 12341 / 12342 Agnibina Express is a daily superfast train that runs in the state of West Bengal, between Howrah Junction and Asansol Junction. The train belongs to Eastern Railway, maintained at Howrah. It connects the major coal and steel industrial cities of Asansol, Raniganj, Andal and Durgapur to the capital city of Kolkata, and is therefore, a very important train on the route for daily passengers.

Initially known as the Asansol Express, the train was renamed the Agnibina Express as a tribute to Kazi Nazrul Islam, whose birthplace is near Asansol and whose first poetry book was titled Agnibina. However, unofficially, the train is often referred to as the Bidhan Express.
