Class Details by Steve Llanso of Sweat House Media

Class Hecate (Locobase 10502)

Data from "New Stock, Kent And East Sussex Railway," The Locomotive Magazine, Vol XI (15 April 1905), p. pp 66-67.

As noted in the Rother Valley Railway entry at Locobase 10149, this southeastern England light railway expanded soon after it opened. This class of 8-coupled tanks was purchased to serve the goods (freight) traffic over the grades between Headcorn and Rolvenden. Note that because it was a light railway, the locomotive spread its weight over 4 axles and all of the engine's mass contributed to adhesion.
