Gare Saint-Lazare is one of the six large terminus train stations of Paris. It is the second busiest in Paris, behind the Gare du Nord, handling 274,000 passengers each day. The first station at St Lazare was 200 m north-west of its current position, called Embarcadère des Batignolles. The station was opened by Marie-Amélie (wife of Louis-Philippe of France) on 24 August 1837. 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. On 27 April 1924 the inner suburban lines were electrified with 750 V third rail. The same lines were re-electrified at 25 kV overhead wires in the 1960s.
