In 1892, the line to Saint-Germain was rerouted to  a spur of the line to Versailles instead of the line to Poissy whilst the line to Poissy was rerouted to a spur of the line to Argenteuil, avoiding crossings. The bridge over the River Seine still had four tracks, but serving two pairs of lines. These modifications were only sufficient for a time as traffic was in constant increase, growing from 26 million passengers in 1888 to 42 million in 1898.
