When first opened this station was named "Holiday Camp" after a nearby camp run by Allnatt Limited - later to become 'The School Journey Centre'. It has also been known as "Jesson" and "Holiday Camp Jesson". Since 1946 it has been known as "St Mary's Bay" apart from a period from the early 1980s until the end of 2000 when it was renamed "Jefferstone Lane". In 2000/2001 the station was refurbished in the current colour scheme of green and cream. A small garden was also established by the booking office. Until the end of the 1990s this station was fully staffed during the summer period. Since then it has been staffed only on special event days or when surplus staff have been available. Generally passengers are now expected to purchase their tickets at their destination. Although no longer a block post for train control purposes, it was able to be used as such until 2000. The station had a single-aspect signal installation in the 'starter signal' position on the 'down' platform. The one displayable aspect was 'danger'. This was unusual in a non-block station. This signal had the outward appearance of being two-aspect, but this was an illusion, as one apparent signal aspect was in fact the repeater flashing light to indicate to train drivers that the adjacent level crossing signals had operated correctly to stop road traffic. A short distance south of St Mary'sBay station a signal box was originally erected to control movements in and out of sidings provided to serve Allnatt's holiday camp, and is marked as such on the title deeds for this part of the station site. When it fell into disuse is unknown. No trace of it can be found today. The station was refurbished and repainted in 2009 by a small group of volunteers, helped by the railway's paid staff, with the aim of the station being opened on special events with small, but appropriate, photographic displays within the booking office. This has already happened during the 2008 and 2009 "Home Guard" weekends. Once the upgrading work on the level crossing has been completed, which involves the installation of level crossing barriers, there are plans to establish the station as a 'Haven for wildlife'. This will include the building of a dead hedge on the up platform, from the end of the toilet block to the Dymchurch end of the platform. Also the garden area will be replanted to encourage local wildlife along with the current assortment of bird feeders and bird boxes that are already present. The station became a request stop in the early 2010s.
