After Quebec Bridge construction in 1917, Palais Station is called a Union Station because the Canadian Pacific shares the facilities with the National Transcontinental Railway and the Quebec Central Railway; the Canadian National will use until 1929 the former QLSJR station built in 1891 on Parent Square nearby. The Quebec Railway Light and Power also had its station nearby (former Quebec, Montmorency & Charlevoix).In fact, both Palais Stations received passengers from seven different railways : the Quebec, Montreal,Ottawa & Occidental Railway (becomes Canadian Pacific), the Quebec and Lake St-John Railway from 1880, the Great Northern Railway of Canada in 1900 (trough QLSJR at Rivière-à-Pierre), the Quebec, Montmorency & Charlevoix (becomes Quebec Railway Light & Power Co) after construction of the swinging bridge on St-Charles River in 1891, the Canadian Northern Railway buys the Great Northern in 1907 and, in 1909, builds a line from Garneau Junction north of Shawinigan to Hedley Junction of QLSJR, the National Transcontinental Railway in 1917 (third transcontinental after CPR and CNoR) and the Quebec Central Railway which use a ferry from Levis to reach Quebec before the Quebec Bridge. In 1918, many railways are near bankrupt and the Canadian Government (which created the problem by building the NTR in the underpopulated northern regions of the provinces) must found the Canadian National Railway to rationalize the rail industry and nationalize the QLSJR, the CNoR, the NTR and the Grand Trunk.
