Gypsum Ore Wagons
Hoppers numbered 26666-26694 were built by CIÉ in 1972 to cater for mineral traffic from Irish Gypsum’s railhead at Kingscourt in County Cavan, which served Irish Cement factories at Drogheda in county Louth, Castlemungret in County Limerick and Platin in County Meath.
Initially, these wagons could often be found in mixed rakes along with ‘Bulleid’ corrugated open wagons. On such occasions the hoppers would always be located closest to the locomotive as they featured continuous vacuum braking, while the open wagons were loose-coupled and required a brake van to be included at the rear of the train. By the 1980s gypsum traffic was carried exclusively by the hopper wagons and this remained the case until the flow ceased in 2001.
