Thanks to Chris / CopCarSS for my avatar.
Yes we are on time but this is yesterdays train

It almost sounds like the train is stopped to manually set these "retainers" to overcome a deficiency in the brake design. Several years back and a couple in a row we stopped each Spring on the way back from Florida...at Saluda, NC at the famous NS grade and talked to people of their famous "hill", etc....and learned that was one procedure that took place there in the town of Saluda..{the grade summit}. Before the crew would even think of starting down the grade the retainers had to be set....So it was mandatory to do this on that hill...dynamics or not. I suppose I just don't quite understand why a brake application from the engineer couldn't accompli***he same thing....Is there a danger of the brakes becoming party released as the train would make it's decent of the hill and hence "turning up the retainers manually prevents this...." ? I know this "hill" would require major breaking power as it was, {is}, a 4.7% grade in general for several miles.....Any thoughts...?
