The Antwerp Lage Zwaluwe railway is an important international railway line running from Antwerp in Belgium to Lage Zwaluwe in the Netherlands. The line was opened between 1854 and 1876. The opening of the high speed lines HSL 4 and HSL-Zuid in 2009 has decreased its importance for international passenger traffic. The HSL 4 is a Belgian high-speed rail line which connects Brussels to the Dutch border. 87 km long, it was scheduled for completion by 2007.
