I have his Consolidation and it's very entertaining to run. !!*ok*!!


Yes, I understood it as a joke, don't worry :D

I'm glad everyone's enjoying the Consolidation !!*ok*!!

I finally finished putting the details onto the sides of the trailing truck.

I'm getting 60fps at Sherman Hill with this, on my usual settings.

In any case, I'll do the same as on the Connie and make it possible to toggle the finer detail on and off with a key combination (ctrl shift 1).

They're all in the same geo file but in separate groups, so when you use ctrl-shift-1 to suppress the display of those groups, you get a corresponding increase in FPS. That's how it is in the Connie, and it works.

Perhaps it makes a difference with TSX because suppressing some geometry detail also relieves the game engine of having to do the detailed shadows they cast.

As promised. The 3rd set I took started at about half of the independent, and I worked up to full. If you look, you can see how little the piston moves after it fully extents. Granted, its a Diesel, will try to get the 9's at a later date when I actually have time.

Thanks!

It's interesting that it moves more quickly when extending than when it's retracting.

Thats because the natural position of the piston is retracted. It has a spring that forces the piston closed (and the brakes released) when there is no air pressure. Also, unknown to many people, car's operate the same way, but in a more complicated way. Its only the air pressure (on a straight air system like locomotive brakes, and certain freight and passenger equipment also equipped with straight air) that forces against the spring, and apply the brake. So when its retracting, it has to work against the escaping air pressure. And thats more powerful a force then the action of the spring.

In case anyone was wondering about car brakes, the triple valve turns a reduction of air pressure into an application of pressure from the car's reservoir. FourEightFour knows more about car brakes and brakes in general then I do.

I get it now, thanks!

I had to learn about triple valves when I was doing the air brake system for the Consolidation, to get it to simulate "peeing away your air". It made for fascinating reading. It really helps to see a cutaway diagram of the car braking system, to be able to understand how the change in air pressure in the train brake line, versus pressure in the auxiliary reservoir, changes the position of a piston in the valve so that different openings are opened, letting air from the auxiliary into the brake cylinder to move the piston and apply the brakes, or shutting that off and instead allowing air to escape from the brake cylinder and release the brakes, and seeing how it recharges the auxiliary reservoir from the train line. Then there's the emergency reservoir to take into account too (which I couldn't do properly in the Connie because of limitations of the core programme ... same story with bail off). Very clever stuff.

I'm gonna save my money to buy all steams and 1 route, maria pass. There are lot of things I bought with the money I used. So when this FEF comes out I'll buy this with the rest. !!*ok*!!

There's still a long way to go, but now that I'm on it 7 days a week (more or less), there'll be some progress every day, so I hope I'm on track for having it ready for Christmas (famous last words?).
