Neptune Refreshments is the Refreshment Lady's main stall located at Lakeside. When on duty, Peter Sam would wait outside at the station for an hour every afternoon before he would take the Refreshment Lady to her "guaranteed connection" with Henry. However, Peter Sam once left her behind by accident, which made her rather upset.

Since its first television appearance in Peter Sam and the Refreshment Lady, Neptune Refreshments has appeared several times in stock footage and has also been seen at Norramby Seaside Station in the eighth season, and one by the Sodor Maritime Museum.
