Emergency escort construction could draw on skills outside specialist warship yards. Sackville's Scotch boilers were similar enough to locomotive boilers that communities experienced in building and repairing railway boilers possessed relevant knowledge. That overlap widened the practical industrial base available for Flower-class construction and maintenance. The original Sackville presentation omitted a longer detour into locomotive boilers to control its length. Shared steam technology linked railways and local repair capacity with wartime shipbuilding.

Sackville's Scotch boilers and railway industrial skills
The Sackville comments connect Scotch-boiler maintenance with the locomotive expertise available in industrial towns beyond specialist naval yards.
