and 54 service vehicles. Incidents and accidents In the Ballymacarrett rail crash of 1871, on 13 May, 2 died and 55 were injured when a passenger train ran into a derailed goods train at Ballymacarrett Junction. The goods train derailed when a drunken fireman drove the train into an unfinished turnout, fouling the line. In the Ballymacarrett rail crash, on 10 January 1945, 22 passengers died and 27 were injured when a railmotor car ran into the rear of a conventional train stopped at a signal at Ballymacarrett Junction. The 7.40 a.m. rail motor Holywood to Belfast crashed into the rear of the 7.10 a.m. Bangor to Belfast train. The darkness and local fog were a factor but the driver of the rail motor was held to blame. The Railway had to pay out some £80,000 in compensation, which crippled the company financially, leading to its early nationalisation in 1948. Downpatrick & County Down Railway The Downpatrick & County Down Railway (DCDR) operates the only Irish Gauge heritage railways in Northern Ireland on part of the former BCDR Belfast-Newcastle main line. It has fully restored and operates several miles of track, including the famous 'Downpatrick Loop', complete with original restored platform. The DCDR operates four railway stations on the line, one of which was the original BCDR Loop Platform. The railway holds a vast collection of BCDR rolling stock and museum artefacts, the majority of which are on display for the public to enjoy. The DCDR's logo is based on a monogram previously used by the BCDR. Preservation Seven carriages that were once owned by the Belfast and County Down Railway have survived into preservation. Among them are three six-wheeled carriages built at Queen's Quay by the BCDR, one of the railway's three railmotors, an 1897 composite bogie coach, the BCDR's royal saloon No. 153, and a six-wheeled carriage built at Dundalk by the Great Northern Railway that was later purchased by the BCDR. All of these apart from six-wheeled third No. 18, built at Queen's Quay, are located at the Downpatrick and County Down Railway. So far, bogie coach No. 148 and ex-railmotor No. 72 have been fully restored, while No. 153 is part-way through overhaul. The other coaches owned by the railway are awaiting maintenance on site. In addition, one BCDR locomotive has been preserved at the Ulster Folk and Transport Museum, Cultra: BCDR No. 30, which was
