A TRS19 and above steam engine spec. for the LNER/BR Class E4 (ex-Great Eastern Railway T26) 2-4-0 with the later pattern LNER boiler fitted from 1940 onwards. Boiler pressure: 160psi. Tractive effort: 14700lbs. Braking values set to emulate vacuum brake performance. This spec uses real world data to the maximum extent possible and will perform most accurately if used with appropriate enginespecs (with VB in the title) for British rolling stock and my AWG Physics rules on the DLS. Please see the included readme.txt for further information.
