Data from [] (a page of the ca. 1920 Vulcan Foundry catalogue). In the same website's [
], two of the locomotives are shown as works numbers 3170-3173.
This was a very "British" quartet of suburban tanks for the metre gauge. They had the usual combination of Belpaire fireboxes and outside constant-lead radial valve gear, long water tanks, trucks with circular holes, and enclosed cabs.
