Glasgow & South Western 0-4-2 Locomotives in Great_Britain

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 3004)

Data from Graham Glover, British Locomotive Design 1825-1960 (London: George Allen & Unwin Ltd, 1967) and Ahrons (1927).

Very similar to his brother Patrick's Great Northern 0-4-2s, these engines by James Stirling were smaller in dimension (although the 1865 series had 17 x 24" cylinders and slightly larger 61" drivers). Note, however, although they were almost exactly the same diameter (48 3/4" in the G&SWs vs 48.5" in the GN), these boilers were larger in proportion to the grate than were those of Patrick's creations and provided more steam under similar circumstances, although the firebox heating surface was less at 78 sq ft than Patrick's engines' 92.4 sq ft.

Class unknown (Locobase 3193)

Data from Graham Glover, British Locomotive Design 1825-1960 (London: George Allen & Unwin Ltd, 1967)

Before he relinquished his post as locomotive superintendent to his brother James and went on to the Great Northern, Patrick Stirling turned out these low-drivered freight engines. Note that they had plenty of boiler and grate for the job.
