Hmmm, just read this, from Karma99, on the Steam forum;

...As I'm currently rewriting the entire wheelslip physics and taking it under the control of script...

I wonder if he saw my video?

Stranger things have happened.

A thought occurs to me. if you have made it so that the loco locks the wheels if braking too hard will the tender wheels also lockup?
As I believe that 844 has brakes on the tender wheels?

That's an interesting thought. The engine is going to communicate with the tender anyway to tell it when to apply its own brakes, so yes, I could also script the tender to lock its wheels. Thanks for the suggestion!

You are welcome mate it was just a random passing thought that I latched onto and posted here to see what came of it

Thought so.

Guilty of that also

Here's the detail on the steam turret. This one still has the Wilson sludge separator in the turret. In more recent photos, the hole's been covered over - UP changed the piping so that the steam would come out further down and avoid dirtying the boiler jacket, but I've modelled it the way it was before.

Why is it called a steam turret anyway? every time I see that name I keep looking for the .50 cals and I don't know why they call it a turret as in my mind a turret is something that holds something else and rotates

"Turret" pre-dates the age of tanks and battleships - remember that castles have turrets. The steam turret does hold something - steam. It's like the steam dome, except that the steam dome collects steam to go through the dry pipe to the steam chest and on through the valves to the cylinders, whereas the steam turret is near the backhead (the cab end of the boiler, where the firebox is) and distributes steam to the various appliances and steam-driven controls, through steam throttles. In the old steam locos, it looked a bit like the turret on a castle.

Every RR museum in the world is going to want one of these!

I see thank you for the info and you are right it does predate tanks and so on but I guess its just a habit of mine now days to forget that little fact oh well

[ozinoz]

She is certainly coming along. Then the "Fun" of the cab starts

Anybody want some heat? I can try and send you some. I will swap for snow 45C here yesterday, same today and possibly 47-48 tomorrow (thats about 120 in the old money)
