Liverpool Lime Street is a railway station complex located on Lime Street in Liverpool city centre. Although publicly a single, unified station, it is operationally divided into two official railway stations: Liverpool Lime Street High Level, the main station serving the city centre of Liverpool and the oldest still-operating grand terminus mainline station in the world; and Liverpool Lime Street Low Level, an underground Wirral line station connected to the main terminal building by a pedestrian subway below street-level.
