Moin, I've run out of things to try to get acceptable braking performance when pulling oil trains over the Pennines. Vacuum brakes, Air brakes, nothing seems to work properly, the trains will barely at all slow down. Getting them to move in the first place isn't that easy as well regardless of loco type. Brakes had been at about 85% for at least a minte at that point. Any idea what I might be doing wrong?
