Thanks for your comments.
Darwin has kindly sent me an improved, tidier ORTS .eng. Have now climbed the Bank, 12mph at summit, 220 psi. (Tangmere was 19mph). Can now maintain 70 + mph on the level (374 tons), so will be able to time service trains! Thanks Darwin!
I have not yet manged to get OR to recognise a custom .eng in the OpenRails folder, hence my mix of MSTS and OR parameters.
The Bulleid pacifics were originally 280 psi, but were all soon reduced to 250 to save maintenance costs. In practice it seems the full 280psi was seldom seen in the steam chests.
Yes, the Upwey/Bincombe bank is as Copperpen describes it. Do please watch the video I gave earlier in the post : it is a real treat!
In service conditions,with varying engine states, rail conditions, the risk of a Bulleid slipping to a standstill was too great, and such heavy trains would have been banked. But the Video of Tangmere shows the loco would not have stalled with a full head of steam and dry rails.
As a result of the kind help with .eng files, I can now time a service train in OR, so I am happy to wait for changes to the code.
As an ordinary user with little mathematical ability the present requirements for OR are a bit daunting. I think many users will give up and return to MSTS. I think maybe to input the OR data as an "include" file maybe helpful. Or better still, a utility to write a .eng from dialed in parameters.
Thanks again for the help, rick
