When I drive the trains on the NTP route and go downhill, I usually use the straight brakes to keep the speed in check. If I understand the terminology correctly, this is the locomotive break. If I try to use the train break, even at initial reduction, it starts to slow the train down too much and I constantly need to release it to gain speed again. In real life, how is it done? I doubt that the driver applies 100% break. Thank you for the answer, in advance.
