>>1834264I think the mistake everyone makes is trying to progressively set more air to make a precise stop, or trying to do the same with dynamics, when using air correctly is so much easier.
First thing to know is you never want to stop a train with any of the independent (locomotive) brakes. You want to use the brakes on the cars to slow or stop but leave the locomotives' wheels free to roll so you can apply power to stretch brake, or apply dynamics to stop.
Trouble with the automatic brake is that it automatically applies the train AND locomotive air brakes every time it's used. To utilize only the brakes on the rail cars themselves, you should bail off the independent every time you apply the automatic, even for subsequent reductions. That will quickly release any air in the locomotive air brake cylinders, allowing them to roll freely so that you can apply the throttle or dynamic braking.
Stretch braking is just setting air on the train and then notching up on the throttle, applying power until you reach a desired equilibrium speed. Then you can reduce power as you get closer to your target and stop pretty quick by going to idle. At around 2-4 mph you can apply the independent as a way of throwing out the anchor if you need it.
