A TRS19 and above steam engine spec for the LBSCR Class H2 Atlantic as running post-1938 with the boiler pressure raised to 200psi. Tractive effort: 24500lbs. 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.
