Hi, I reached the summit of Sherman Hill and started my decent down the grade. I started applying my dynamic brakes and eventually they weren't enough to keep the train at the speed limit. Keeping my dynamic brakes fully applied, I applied minimum reduction on the automatic brakes to try and contain my speed. However, it seemed the dynamic brakes slowly released when I did this which led me to speed up even more. The same happens when applying the independent brake as well. To conclude I don't think the dynamic brakes work at all when the independent and/or automatic brakes are applied. Am I doing something wrong or is this a bug?
