Until the end of the 19th century, the typical ballast wagon was a primitive short wheelbase vehicle, with low drop sides, leather flaps to try and keep the stone dust out of the grease-axle boxes and, possibly still, dumb-buffers. To go with these, there might be a “ballast brake van,” often derived from an even older four-wheel coach, and sometimes a sort of combined tool shed and mess hut on wheels. But, from the 1890’s, a number of companies, including in Ireland, the GSWR, MGWR and GNR(I), started to modernise their permanent way stock, introducing higher capacity steel hoppers, where instead of shovelling the ballast out of low-side wagons, it could be deposited directly onto the track through bottom doors, and also “plough vans” with steel shears underneath, which at least started the process of distributing the gravel. These drawings show the GNR designs of the period, and a very similar, but later, design for gypsum traffic. The plough vans and eighteen hoppers came from Hurst Neilson & Co. of Motherwell, and were of all-steel construction. The ballast wagons had self-discharging hoppers, which could be operated by screw mechanisms from either side.  The van had double plough-shears between the wheels, so it could operate running in either direction, a large veranda and a covered portion with stove and lockers. All this stock had vacuum and hand brakes, and oil axle-boxes. An unusual, and it seems only experimental change was the use of “GNR(I)” lettering, instead of the more usual “GNR” and later “GN,” although since this only appears on the Neilson maker’s photos, it may have been their whim, and rapidly replaced by the orthodox legend on arrival at Dundalk. Similarly, although the posed official shot shows the van running as number 120, the GNR drawing lists them as 8166 and 8167, both built in 1910, and costing £242 each. Similarly, the Neilson hoppers, all built in 1910 at £138 each, had running numbers  8097-8114. Another nine hoppers came from Pickering in 1912, at £149 each, running as 8139-8147.

At the dissolution of the GNR, UTA got fourteen of the hopper vehicles, and the remaining thirteen went to CIE, for which the following details are recorded:

The gypsum hopper drawing does not have any notes about outside builders so I assume they represent Dundalk’s adaptation of the earlier ballast hoppers. Six of these were turned out in the Second World War (or did the GNR call it the Emergency, or like the Church of Ireland prayer book for “our leaders” have different rubric for each side of the Border?).  I am assuming that these worked from Kingscourt on the MGWR, being handed over at Navan and forwarded on GNR trains to Drogheda cement factory. These vehicles were built with hand brakes only but cost had risen to £477 each (£205 wages, £235 material, £37 other charges), and the following details apply:
