A TS2019 and above steam engine spec for the LSWR N15 class 4-6-0 locomotives designed by R.W Urie in as built condition. Boiler pressure: 180psi. Tractive effort: 26245lbs. 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.
