When your locomotive is traveling across flat terrain and simply maintaining speed, you will hear your locomotive chugging along. But, when the locomotive encounters a grade and the engineer applies more throttle to get the train up the hill, the engine sounds will automatically react and reflect the increase of power needed to crest the hill. DDE accomplishes this by calculating the changes in strain or load on the motor and adjusting the exhaust to appropriately simulate the work the engineer would be doing to the throttle of the engine. This gives Tsunami2 the ability to create \u003cstrong\u003ethe most realistic experience possible.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHIGH QUALITY SOUND LIBRARY\u003cbr\u003e\u003c\/strong\u003eOur large selection of high quality sound effects include: \u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e8 Prime Movers  \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e14 Bells \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e40+ Airhorns\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAdditional couplers, dynamos, cab chatter and more!\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eADDED REALISM\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003eAdditional realism can be simulated by adding functioning locomotive and train brakes, injectors, power reverse, firebox flicker and more.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eEASY INSTALLATION\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003eThe TSU-KN1 comes with a complete installation kit ensuring an easy install.
