Comment 1 for bug 1391449

There is actually a temporary patch to get round this, hence the fact that the brakes do eventually release.
What happens is that the code provides for the brakes to release when the controller is set to "Running". The problem is that the "Running" sector, like the "Apply" sector works from 0% to 100% in the same direction. Therefore, if you go to full "Running" (0%), if that's not a confusing statement, which is the natural "stop" when you move the brakes to release, the patch releases the brakes at a near zero rate. The "Running" sector of the brake controller is so small on these locos that you move from 100% to 0% in a blink of an eye. When releasing the brakes, if you try to stop the controller AS SOON AS IT ENTERS the "Running" sector (you'll see the percent "Running" when you lift your finger off the key), the brakes will release at a more realistic rate. You often have to juggle back and forth to get near the 100% "Running", the best release rate.

I have a personal patch which gets round this problem, I haven't volunteered it because I've assumed that the Injector controls will eventually be implemented.
