Rhondda & Swansea Bay 2-4-2 Locomotives in Great_Britain

Class Details by Steve Llanso of Sweat House Media

Class 17 (Locobase 10336)

Data from "Rhondda & Swansea Bay Ry," The Locomotive Magazine, Vol VIII (13 June 1903), p. 405.

A sketch of the R & SB is presented in 10335. Here we note that the passenger tanks shown in this entry of decent size and power for their requirements. In fact, they shared all basic dimensions and weighed nearly as much as the radial tanks described in 10335.
