That's good. But not quite right. A good diagrammatic is in Wikipedia, here:

The Eccentric Rod makes the Link rock backwards and forwards, and this causes the Radius Bar to also move back and forth.

The Reverse Arm and Shaft lifts the Radius Bar within the slot in the Link. At full forward motion the Radius Bar is at the lowest point in the Link and the back and forth motion of the Radius Bar is at its maximum. This maximises the movement of the Valve Spindle, allowing the maximum amount of steam into the cylinders. As the Radius Bar is lifted within the slot the movement of the Radius Bar is reduced. This is the "cut off". At full reverse the Radius Bar is at the top.

Ben Neal managed to get this just right in his locomotives. To see it in action download, for example, his Baldwin 2-6-0 Mogul. "Loco Baldwin 2-6-0" on the Download Station works error free in T:ANE and TRS19, and shows the valve gear to perfection.

There's also an infinite number of youtube videos, for example:

Thank you, Phil for the comment. :)
As far as the Eccentric Rod is concerned, mine does indeed push the Radius Bar back-and-fourth. It may have been hard to see, since it was positioned in the middle.

But yes, I didn't properly model that Reverse Arm and Shaft, but I plan to remodel it. Thanks for pointing that out.

Also I finally imported my first animated asset into trainz

A long way to go!



Interestingly, developing this, I did it via remote desktop connection from work (When I was allowed to take my thin client/tablet to a cabin I use) even though my 4G connection that I had to use was next to useless. I also used a different method to create the body, got into cross sections using splines and diagrams. I was really surprised how well it turned out - the only downside is my idea of putting the windows in at the same time as making the body just didn't work and the poly count went over 100,000!
 
A UK wagon, nice change of pace there :D

I tried something similar a while back, it might be put to good use with Rileyzzz’s compressing buffer script.

Tony Hilliam mentioned a physics API, hopefully we can script handbrakes and their resistive forces (and perhaps even some vacuum brake simulations) to put something like this to use.

Interesting. Thanks for the info. Hope I can implement this into Trainz soon...
