context_page_description: The HSL 1 is a high-speed rail line which connects Brussels, Belgium, with the LGV Nord at the Belgium–France border. It is 88 km long with 71 km of dedicated high-speed tracks and 17 km of modernised lines. Service began on 14 December 1997.
  The line has appreciably shortened journey times, the journey from Paris to Brussels now taking 1:22. In combination with the LGV Nord, it has also impacted international journeys to other cities in France and to London, ensuring high-speed through-running by Eurostar, TGV, Thalys PBA and Thalys PBKA trainsets.
  The total construction cost was €1.42 billion. The signalling system installed is the TVM-430 in-cab signalling system, the same as LGV Nord in France, and High Speed 1 in the UK.
