structure, was moved brick-by-brick from Kingsbog Junction on the Belfast–Derry line. Downpatrick East Signal Cabin, a GNR structure, was originally Bundoran Junction's North Cabin. It was moved to DCDR in 2011 and opened to the public in 2017. Downpatrick Locomotive Shed, a BNCR structure, was moved stone-by-stone from Maghera where it was originally the goods shed. Downpatrick Station Canopy was originally attached to the Maghera Shed. Downpatrick Water Tower was moved from Antrim station. The Arch, which spans the main gate, bears the name of the railway and is based on an original design at Cookstown. Bridges 163 & 164 are original BCDR bridges, and carry the Back and South lines respectively across a narrow stream. Downpatrick Loop Platform and Canopy are the only BCDR buildings left in Downpatrick. The Cutting is just beyond the limit of passenger operations on the South Line. It carries trains up a slight gradient, with vertical retaining walls on either side. The Quoile Bridge is the longest bridge on the DCDR. It carries the North Line over the River Quoile, and though the spans are newly fabricated, the concrete centre pier is original. Carriage Gallery Completed in 2012, the Carriage Gallery is the DCDR's museum with rolling stock that is not being used to run public trains during their visit. Like the Ulster Folk and Transport Museum, the Carriage Gallery houses vehicles in an indoors environment where the public can get up close and learn about both the vehicles in question, and Irish railways in general. Despite its name, the Carriage Gallery also contains locomotives, both steam and diesel, and even a road-going tar boiler. Designed in homage to the Victorian railway termini with their grand overall roofs, the Gallery collection is arranged across 3 roads with 4 platform faces, allowing visitors the chance to enter the vehicles. The condition of the exhibits ranges from fully restored to as-discovered so that visitors can appreciate the huge work required, with some carriages still in the hen-house state they were found in on farms across the country. The Carriage Gallery was officially opened by the Earl Of Wessex in 2014.
