Gare Saint-Lazare is one of the six large terminus train stations of Paris. It is the third busiest in Mainland Europe. The first line served was the single track line to St Germain-en-Laye. In 1843 St-Lazare was the terminus for three lines; by 1900 this number had tripled. The station had 14 platforms in 1854 after several enlargements, and now has 27 platforms sorted in six destination groups.
