Shanghai Railway Station (Lines 1, 3 and 4) is a major transportation hub in Shanghai, containing the railway station, two subway lines and the stop for many city bus lines as well as interprovincial buses. These bus lines will soon be housed in a brand-new bus station. The line 1 platform is in the South square while platforms for line 3/4 are in the North square. These two platforms are technically separate stations, so interchange is only possible between lines 3/4. A transfer to the line 1 platform requires a SPTC or a new ticket.
