The farm was built up by the Wille family from the 1830s, who were originally Germanmissionaries. Today it is part of an international agri-business that produces wheat, soya beans, maize and sunflowers. It has been 100% organic since 2005.
Sandstone Heritage Trust
As steam enthusiasts, in the mid-1990s, the Sandstone owners were approached by Alan Clarke of Transnet Heritage Foundation, who realised the foundation did not have the resources to rescue the collapsing Midmar Museum in KwaZulu-Natal. The collection formed the basis of what became the Sandstone Heritage Trust. Today, the trust's main collection is still based around the railway transport of Southern Africa, but also covers an extensive global road transport and military vehicle collection. The "Stars of Sandstone" 10-day event held in March, April or May attracts thousands of visitors, 70% of whom are from overseas. NG15 2-8-2 No.17 leaves a station at Sandstone Estates, February 2005
Agricultural machinery
Old tractors which had been on the farm for many years were retained, and added to by donated items. Today the collection runs to over 700 tractors, all were slowly restored to operation.
Railways
The narrow gauge railway runs from Grootdraai in the south, for some northwards to the main farm and main depot at Hoekfontein, onwards via Mooihoek to Vailima Sidings/Ficksburg and the a large loop at Vailima Village. Today the collection of narrow gauge locomotives and rolling stock is one of the most numerous in the world. During the 1990s the Trust took occupancy of the old South African Railways steam workshops at Ficksburg, located alongside the Transnet Freight RailBethlehem to Bloemfontein line. As well as acting as a collection and restoration point, it also acted as a training college for local young people, who were trained through the restoration process. Sandstone now operates a major locomotive refurbishment programme at its Bloemfontein workshops. This is located in the old Steam Depot which was the home of constant Steam activity for many decades. The Trust has 22 locomotives in use on the estate, with another five are under restoration in Bloemfontein.
Military
The trust formed a joint-venture with the South African Army's Armour Museum in Bloemfontein, which led to the development of a significant collection of vintage military vehicles. The collection is built around educating visitors on the history of South Africanmilitary engineering since World War II. The School of Armour plays an important role in the semi-annual "Stars of Sandstone" event, with daily displays and convoys of military vehicles.
