But I think the diagram for the triple valve is poor/ lacking, especially when compared to the details of the brake cylinder's reservoirs.

when there's a major flow into the train line, then gradually recovers back up to the nominal 90 PSI operating pressure. I like how the red needle for the main reservoir pressure drops about 20 lbs. Once it 'loads' - which can take a minute or so - it asks you to click to Start, then it mostly runs itself. The initial screen is a little confusing - don't start with the left-most 'button' for " D etailed Brake Operation ", but instead click on the middle button for " B asic Brake Application " next go the Detailed one, and then go to one of the 4 " S cenarios " at the right side. The 1st link below takes you to a little 1-paragraph explanation from Trackmobile, from which you can then click on the link to go to the "Train Airbrake Animation ", or you can just click on the 2nd link and go to it directly : If you make the small jump in your imagination from "Trackmobile " to a real locomotive, you'll be close - and I'd say this has about 80 percent of what I'd like to see, which is plenty good enough for now. It's pretty neat -I'd been wishing for something similar 'on-line' so a user could see how a real air brake system operates at various points in the locomotive's air system and the trainline - although it won't be confused with the MicroSoft Train Simulator or other sophisticated application or simulation software. While looking for something else, I stumbled across the above.
