	As built condition

The Great Southern & Western Railway (GS&WR) Class 321 consisted of twelve 4-4-0 locomotives built in Ireland by Inchicore railway works in the period 1904 to 1906 as express passenger locomotives.^[1]^{: 106–112}^[2]^[1]^{: 108–112}

Rebuilding

The members of the class were subject to various rebuilds throughout their life including fitting of superheated boilers which improved their performance.^[1]^{: 108–112}

Service

When introduced these were the premier express passenger locomotives of the GS&WR and worked on the Dublin to Cork and Limerick.^[2] They were subsequently displaced by later build locomotives but remained useful for other services where a medium locomotive was required and were noted for a good turn of speed.^[1]^{: 106–112}
