Ulster Railway

[2] The first 7 miles 60 chains (12.5 km) of line, between Belfast Great Victoria Street and Lisburn, were completed in August 1839 at a cost of £107,602 11s.

In order for Dublin and Belfast to be linked without a break-of-gauge, in 1846 the UK Parliament passed an Act adopting a compromise gauge of 5 ft 3 in (1,600 mm) for Ireland, to which the Ulster Railway's track was then re-laid.

[7] This connected the D&D with the Ulster Railway, thus completing the main line between Dublin and Belfast.

[8] The PD&O reached Dungannon in 1858[5] and Omagh in 1861,[9] and the contractor, William Dargan, sold the Ulster a 999-year lease on it in 1860.

33, built as a family saloon in 1862 and withdrawn in the 1920s having passed into GNR hands, is preserved at the Downpatrick and County Down Railway.

These features include rounded tops and bottoms of the windows, door handles placed below the normal waist line in stagecoach manner for access from lower platforms and internal water piping within the frames in a mixture of hessian hose and lead fittings.

A similar sized 6-wheeled Ulster Railway coach was part of the train involved in the Armagh accident (1889), but by this time the Smiths simple vacuum brake had been fitted and the under frame may have been renewed, so exact details are unknown.
