The **[Great Southern Railways](/source/Great_Southern_Railways) (GSR) Class 700** consisted of five [0-6-0](/source/0-6-0) locomotives built by [Inchicore railway works](/source/Inchicore_railway_works) in 1929 and were the last locomotives designed by J. R. Bazin.[2] The **Class 710** consisted of ten [0-6-0](/source/0-6-0) locomotives built by [Inchicore railway works](/source/Inchicore_railway_works) in 1934.[3]

## History

### Class 700

The design was more traditional with a saturated [Belpaire](/source/Belpaire_firebox) boiler that was unique to the 700 class.[4] It was also fitted with slide valves as opposed to piston valves.[2] The tenders used initially were those reallocated from withdrawn 360 class [4-6-0](/source/4-6-0).[2] A more modern feature was underslung springs.[2]

Operationally the need for the class has subsequently been questioned and speculation has arisen that it was to use up surplus type 60 boilers.[2] This class seems to have compared poorly with the older [101 Class](/source/GS%26WR_Class_101) when especially when the latter were fitted with superheated boilers, possibly due to an inadequate heating surface leading to high coal and water consumption.[2]

### Class 710

They were more modern than the five Class 700 [0-6-0](/source/0-6-0) introduced in 1929 though being more modern with piston valves and a type Z superheatered boiler. They could be thought of as a tender version of the [GSR Class 670](/source/GSR_Class_670) [0-6-2T](/source/0-6-2T) introduced in 1933 but with smaller wheels more suited to branch and goods work. Whilst intended as a modern addition to the [101 class](/source/GS%26WR_Class_101) they seemed to gain a reputation as poor steamers and heavy on coal and water. Following their introduction the GSR resumed rebuilding the 101 class with the Z-type superheated boiler[3]

#### Model

There is a detailed [O Gauge](/source/O_Gauge) model of engine 710 in the [Fry model railway collection](/source/Fry_Model_Railway).[5]
