Completed in 1848, it was the first railway to reach the coastal port of Calais. The Paris-Lille railway had reached Lille from Paris two years previously.
In 1993, it was bypassed by the LGV Nord high-speed line running from Lille-Europe to Calais-Fréthun and the Channel Tunnel. The main traffic today is freight and local TER Nord-Pas-de-Calais passenger trains.
