The Shillingstone Railway Project (formerly the Shillingstone Station Project) is a heritage railway project based at Shillingstone railway station on the former Somerset and Dorset Joint Railway. It is supported by the North Dorset Railway Trust (NDRT). The medium-term aim is to restore the current leased length of 46 miles 58 1⁄2 chains (75.21 km) to 46 mi 76 1⁄2 chains (75.57 km) from Bath Junction: an addition of 1,200 feet (370 m) of single track mainline with a loop through the platforms. The signal box, coal store, motor trolley hut, permanent way huts, signals and pole route will also be rebuilt, the signalling being controlled by the box in time. The North Dorset trailway runs alongside the formation and up over the 395-foot (120 m) 'down' platform.
The station building currently houses a waiting/refreshment room, shop and offices. The former parcel shed contains a small museum. The bike shed has been rebuilt from its foundation ring. The south end of the up platform has been rebuilt and the picnic area above landscaped.
In 2009, 210 feet (64 m) of the up main track through the station was laid and ballasted using 110a and 113a flat bottom rail and wooden sleepers. The Ruston & Hornsby diesel shunter was moved from the isolated goods dock. This is the first standard gauge loco on the Somerset & Dorset mainline south of the Mendips since the demolition train departed in July 1967, exactly 42 years before. The wooden box van has also been moved to the same track. Progress in 2010 included acquiring a tracked Priestman Mustang excavator, finishing construction of the up platform wall, regrading of the cattle dock track bed and preparations for tracklaying, and the connection of the station to the mains drainage system.
On 9 and 10 May 2015 two new arrivals where added to the stations fleet, a class 48DS 4wd Ruston a long time since the previous ruston was sold. This arrived along with an ex-virgin cross-country kitchen coach No.11062
