It opened in 1993.[55] Its extensions to Belgium and towards Paris, as well as connecting to the Channel Tunnel, have made LGV Nord a part of every Eurostar journey undertaken. A Belgian high-speed line, HSL 1, was added to the end of LGV Nord, at the Belgian border, in 1997. Of all French high-speed lines, LGV Nord sees the widest variety of high-speed rolling stock and is quite busy; a proposed cut-off bypassing Lille, which would reduce Eurostar journey times to Paris, is called LGV Picardie.
