Platforms 1, 2 and 3 are within the main train shed; Platform 4 on the south side is in the open air. A large stone at the end of this platform welcomes people to Penzance in two languages: English and Cornish. This side of the station is built on the sea wall near the harbour, the other side is cut into the hillside. It is both the southernmost station on the National Rail network and the westernmost station in England, although not Great Britain as some stations in Scotland are further west. The station is operated by First Great Western as is every other station in Cornwall.
