Gelert's Farm Works is the operating centre for the Welsh Highland Heritage Railway (WHHR).
The farm, which is situated between Beddgelert Siding and the Cambrian line, was purchased to become the operating centre for the rebuilt Welsh Highland Railway (WHR).
The next major development was the construction of the RED[clarification needed] Shed north of the main yard alongside Farm Junction.
During this period the shunting neck parallel to the main line was extended to the site of the old trans-shipment wharf where two sidings were laid.
By 2003 the WHHR had decided that its future lay in becoming the heritage centre for the entire WHR.
It was realised that more covered accommodation, workshop space and sidings would be needed over the next ten years.
The Civvies Shed had ceased to be used as a workshop, had become a depository for junk and was thought to be in imminent danger of collapse.
A concrete pad 45 by 10 feet (13.7 by 3.0 m) was laid at the end of the siding for the new Diesel Shed.
