The Midland Great Western Railway bought 12 kits which were then assembled at its Broadstone works in Dublin.

[4] The first entered service as MGWR number 49 but the company then became part of the new Great Southern Railways and the locomotive was renumbered 375 and the remaining 11 kits were completed as GSR engines.

Córas Iompair Éireann succeeded the GSR in 1945 (and was nationalised in 1950), retaining the same classification system and numbering for its locomotives.

[8] On 21 December 1955, number 375 was in charge of such an unfitted train consisting of 32 wagons laden with sugar beet.

[8] The train was on the line between Waterford and Limerick Junction on CIÉ's Southern section when it ran away descending the gradient to Cahir.
