Former Railway Foundry original building and NE cross range only (now Hafren Furnishers warehouse)

This is a two-storey red brick building, originally part of a railway foundry, and dating from the 18th century. Only the main building and a cross range to the north-east remain. The building is now used as a furniture warehouse.

The main elevation is a long, 26-bay southwest-facing side with small pane glazing and twin hipped slate roofs with bracketed eaves. The windows are fixed and arranged in arched recesses on both floors, with a freestone band separating the levels and stock brick banding around the arches. Historic views indicate a tall industrial chimney was located near the north-east end of this facade. The ground floor windows are recessed, suggesting a design influenced by a classical market hall, with projecting plinths at their bases. A central entrance has sliding doors, and some ground floor windows have been blocked. The northwest end wall, with four windows, also has a stock brick band between the floors and cambered brick arches over the windows. The upper floor has a boarded loading door with brace plates, and a modern window on the ground floor replaces a former doorway. The return elevation to the north-east is partially obscured by later extensions. It features segmental headed small pane windows, including two 20-pane windows flanking a former broad entrance, which has been infilled. A further doorway has been blocked at the right end.

A cross range, constructed around 1900 using Ruabon brick, projects at a right angle to the north-east. It has a pedimented gable end with a circular attic window and arched, fixed small pane windows on either side of sliding doors. Its side elevation, which faces the main railway line, has pilasters dividing the bays.

The northeast gable end is splayed due to the earlier presence of railway tracks leading at an angle from the main line into the foundry. Both narrow and standard gauge tracks are visible in the paved areas of the later ranges, where they passed through, along with retained turntables. These tracks served both the foundry itself and an adjacent yard.

Inside the original range, the roof structure features blackened timber king post trusses. The north-east cross range, formerly known as the ‘Top Shop’, is also internally visible.
