When I visited this station Liverpool Lime Street was shut so all the trains were being diverted here, so I am not sure what a typical day would bring.
Liverpool South Parkway has 4 platforms and 2 Mersyrail only platforms. It has great visibility and good facilities with vending machines and waiting rooms. There are a lot of stairs between platforms so it can take a long time to get from one end to the other. There is a depot just outside Liverpool South Parkway which you can see from the concourse to all the platforms – a bridge with glass. You can see a lot of Northen Trains parked up there such as class 319’s and class 323’s.
