I think I found part of the answer. Looked at the DCS manual online, which shows that the chuff rate can be changed from 2 to 3 or 4 per driver revolution with the DCS controller. It said that the default setting is 3, deemed "best sounding" for high-speed steamers. So I may have to find a DCS system to reset It.</p> <p>Why would anyone want 2 or 3? That's silly. Otherwise, the engine seems to have decent sound and operation, although nothing about the sound can be modified except the volume, or about the speed curve, etc.</p> <p>Hal</p> <p> </p> <p> </p> <div style="clear:both;"> </div> <p> </p> </div> </blockquote> <div class="quote-footer"> </div> <p> </p> <p>I am not in O tinplate or O Lionel but the 2 chuff per rev was an option since many of the models are run at high speed and the two chuffs is used. I was not aware of the DCS having that option for HO, but it sounds like a carry over from their O scale products. </p> <p>CZ</p> <div style="clear:both;"> </div> <p>[/quote]</p> <p>If you run the O-guage trains at the maximum 120 smph the 4 chuffs per revolution sounds absolutely horrible.</p>
