Data from "Locomotives of the Bristol & Exeter Railway," The Locomotive & Railway Carriage & Wagon Review, Vol IV (March 1899), p. 35. . Boiler pressure is an estimate.
These were positively the last locomotives to be ordered by the B & E before its amalgamation with God's Wonderful Railway. In fact, they never operated under the original numbers, but bore the GWR's 1358-1359 as soon as they entered service.
