[quote user="dekemd"]<p>Wabash1,</p><p>Why is a short train hard to run?</p><p> </p><p>[/quote] Not Wabash, but I'll help out with the answers.</p><p> </p><p>A short heavy train will react to changes in grade much faster than a long heavy train. A long train has the tail end holding you back as you crest a grade and start down, while a short train will get more than half the train over the top in a hurry and away she goes. The weight of the train will help pull you over the top.</p><p> </p><p>Also, a short train will react to short grades where a long one will not gain near as much as the whole train is not on the hill.</p><p> </p><p>A good example is a loaded sulfur train. Around 10,000 tons and 3200 feet long. You are in and out on the throttle on these things all the time. Since AC4400's react so slowly to the throttle I end up using the air a lot on these things. Most every downgrade of any length at all and the brakes get set. Being just 3200 feet long, you only need to be about 1500 feet past the crest of the grade and the train starts pulling you over and away it goes.</p>
