 Above the station site and mouth of the tunnel is Caledonian Mansions which was built by the Caledonian Railway company on land it purchased for tunnel construction.The company's monogram is still visible on the east side of the mansions on Caledonian Crescent, just uphill from the station site.At the north west corner of the site the formation of the line from the station towards Botanic Gardens passes under Otago Street where the station buildings were located, before entering the tunnel under Great Western Road.
