Work continued on expanding the Midland Railway – Butterley with the line being extended firstly to Ironville and then almost to Pye Bridge in the east, and to Hammersmith in the west.
Stations were constructed at Swanwick Junction and Hammersmith. Signal boxes were obtained from Ais Gill (on the famous Settle and Carlisle line), Kettering and Kilby Bridge and put into operating condition at Butterley, Swanwick Junction and Hammersmith respectively. A locomotive shed was erected at Butterley (since changed to the Carriage and Wagon department) and the museum was erected at Swanwick Junction, together with a large track fan to provide rail access to the building.
Facilities for the overhaul, maintenance and servicing of steam locomotives were then developed at Swanwick Junction, together with the erection of a heavy repair shed and machine shop. Over many years a Stationary Power Museum, a Road Transport Museum and the Fork Truck Heritage Centre have been established by affiliated organisations and the first phase of a diesel depot has been built. Swanwick Junction now also has the Trust’s Demonstration Signal Box, the railwayman’s church from Westhouses and the gate house and coal merchant’s office from St. Mary’s Goods Yard at Derby. The years of hard work are clearly visible at the Midland Railway – Butterley.
The narrow gauge railway is now well established with its line extending to Golden Valley, following the route of the original tramway from the Butterley Company, together with stations and a running shed.
The Swanwick Junction Museum Complex is also the home of the Princess Royal Class Locomotive Trust who have their own facilities at the West Shed. The Historical Model Railway Society also have their headquarters at Swanwick Junction.
The Trust is open for passenger services most weekends of the year and every day during the Derbyshire school holidays. Special events are run throughout the year.
