With the objective of connecting all the towns on the Northwest coast to Lille in less than an hour, the Nord-Pas de Calais région has put in place TERGV. Certain trains, with the agreement of the SNCF, use the LGV Nord from Lille-Europe to reach their destination instead of conventional lines. This enables them to connect Lille to Calais, Boulogne-sur-Mer, Dunkirk and Arras in less than an hour.
increase frequency of service between Lille and Lens
create a new high speed regional service between Fourmies, Maubeuge and Lille, to reduce travel time from an hour and thirty minutes to forty-five minutes.
