Until 1967 the station was the closest to the airport, but the establishment of Ronaldsway Halt in that year effectively gave a more convenient place to alight for potential commuters.

The town itself was considered to be second only to Douglas in importance to the island; with its bustling harbour and active agricultural scene, the station's importance remained until the final days of operation with livestock being transported from the station's cattle dock (the remains of which are still visible today) until the final year the railway operated its full network in 1965, although the line did reopen to passengers only later.

Today the structure is used only for storage and is occasionally open to the public as part of railway events annually, when it is used to store goods stock and road vehicles.

At this time the station master's office was halved in size to create a booking hall and a new internal ticket hatch installed, the original being blocked off the waiting room was also reopened, having been closed for over 30 years.

During the winter of 2012 the partition in the booking hall was removed, recreating the full sized office, and the fireplace reinstated; the original ticket hatch was also brought back into use.

Also at the station, to the side of the goods shed in a gravelled raised section of the lawn is a large cast concrete Triskelion or Legs Of Mann at platform level, painted in a yellow and red colour scheme.

Linley & Co., was also displayed on the up platform for many years, a similar version is extant and used to operate the unique slotted post semaphore signal which protects the station's southerly side.

The Friends Of... volunteer group were successful in obtaining planning permission in 2016 to erect a replica advertisement hoarding up the up platform on the site and with fund from Culture Vannin began works shortly thereafter; after a number of setbacks, not least of which the various lockdowns during the Covid-19 pandemic, the large timber baulks were installed in early 2022 and as the season progressed further fundraising was achieved so that the remaining timber could be sourced and delivered to the site; by mid-September work began on erecting the hoarding itself with a view to completion in readiness for the railway's south line 150th anniversary in 2024 and with sponsorship from Bushy's Brewery secured it was completed in time for the plaque unveiling and community event on 2 August, anniversary day itself.

To the northeasterly side of the station lies this park, provided and funded by a generous benefactor to the town and being established at around the same time as the railway and it is from this benefactor that the park takes its name; it consists of a large grassed area and is surrounded by perimeter railings within which are contained playground equipment for children and two football/rugby pitches which form the home grounds and changing rooms for the local clubs.

A macadam pathway around the perimeter of the play park, and sporting fields is a popular with walkers and a regular Walk & Talk event takes place here.

The live-action film version of Thomas The Tank Engine was partially filmed at the station, forming the basis of Shining Time Station (itself a variation of the series screened in the U.S.) in the story and the building and its environs were considerably disguised for this purpose, with a temporary canopy being built in the place where the original had once stood; whilst being a temporary structure this canopy looked remarkably similar to the original which had been demolished some seven years previously.

The railway was used extensively during filming, with Port St. Mary goods shed being transformed into a workshop for the purpose and other island locations were also used including the Tynwald Hill Inn at St. John's.

In 1975 the railway only operated between Castletown and Port Erin so it acted as a temporary terminus; this was as a cost cutting experiment but was deemed to be failure not serving the capital.

The following year saw services extended to Ballasalla which again proved unsuccessful, so in 1977 the full line reopened (with government subsidy from the then Tourist Board), again seeing Castletown again regularly used as a passing place.

In 2020 the season commenced as scheduled but in the second week of operations the island was placed on lockdown owing to the Covid-19 pandemic and services did not resume until July, albeit to a curtailed timetable, continuing until early November.

In both 2023 and 2024 special timetables were operated on key dates to tie in with the one hundred and fiftieth anniversary events, the latter notably seeing Ballasalla Station reopened for just one day.

The train was hauled by No.13 Kissack and the party travelled in Royal Saloon F.36 (now on display in the Isle of Man Railway Museum in Port Erin) into Douglas Station, passing No.4 Loch where it was acting as standby locomotive.

On arrival in the capital Her Majesty also travelled on the Douglas Bay Horse Tramway riding tramcar No.44 which thereafter became known as the Royal Tram, painted in a patriotic red, white and blue scheme for the occasion.

The station building and goods shed are dressed with period posters and memorabilia, with all traces of modern signage and additions being removed or concealed for the duration of the event.

As part of a new initiative operated by Manx National Heritage, the local authority Castletown Commissioners and the railway the revamped services saw trains bring passengers to the station on an hourly basis for a short shuttle bus ride to Castle Rushen where Santa's Grotto was located in addition to traditional market stalls, fairground rides, an enchanted forest walk and snow machine.

As part of the experience the unusual step of allowing buses into the relatively small station car park was permitted and the Tinseltown Shuttle departed at regular intervals, echoing the latter years of Railway Company operation when Road Services buses called at the station at regular intervals when the rail-based services were restricted during the winter months.

On Monday, 12 September 2011, the station played host to the official parties connected with the 2011 Commonwealth Youth Games with the "culture day" prior to the closing ceremony of the event taking place in the town; to accommodate the vast numbers travelling on this occasion passenger services on the railway were suspended for the day whilst the competitors and officials were transported by rail to the station.

The event is designed as a small-scale version of the Commonwealth Games aimed at children and young people; past hosts have included Bendigo in Australia and Pune in India.

Once competitors arrived at the station they were transferred to the town square by four Wright Eclipse Gemini buses provided by the island's nationalised Bus Vannin arm of the transport division.

Each December since 2013 the railway's dining train has operated regularly with a range of festive meal options and the majority of these services use the station as a terminus for both daytime and evening trains; the station is fitted with colourful festoon lighting and decorations are provided by the Friends Of... volunteer group each December and into January when it is common for afternoon tea, brunch and commuter services to call prior to the closure for maintenance.

5 Mona during the day, with other stations taking on dual roles, Port Erin becoming Ramsey and Douglas becoming St. John's; the request stops at both The Level and Ronaldsway Halt were not renamed, with bin liners covering the running in boards at these sites.

The original halt at Ballavolley opened during the summer of 1965 upon the establishment of the Wild Life Park, consisting of a simple running in board and ground level grassed platform.

Commemorations took place as part of the larger Manx Heritage Transport Festival focussing on locomotives No.4 Loch and No.5 Mona, both built for the opening of the line, the latter being cosmetically restored by the Isle of Man Steam Railway Supporters' Association for the 2023 celebrations and displayed on the site for the day together with the Foxdale Coach and No.24 Betsy and No.25 Sprout.

Opened during strike action taken by employees of Bus Vannin during 2012, this temporary station was located approximately three-quarters of a mile to the south-west of the station and was used only by local school children attending Castle Rushen High School; it consisted of temporary scaffolding platform with a capacity for five carriages, and operated only when the buses were on strike, at which times special trains replaced the bus service.

In 2014 the group held its first Summer Fayre on the site, raising funds for various projects including the proposed reinstatement of the station's advertisement hoarding and a replica cattle dock.
