Until the opening on 2 June 1996, of the first phase of the Belgian high speed line,[63] Eurostar trains were routed via the Belgian railway line 94. The Eurostar routes still use the line as a diversion if engineering works are taking place on HSL1, depending where it is. The 06:13 from London St Pancras to Brussels still uses the line as a diversion to bypass the peak time disruptions on HSL1 due to the extra TGV services from Brussels for the commuters.
