There is a bad volume level in the Trs2010 as far as the engine's acceleration is concerned. The volume is to low for the steam engines and other locomotives. And that is intrigrated into the Trs2010 code and can not be fixed without another service pack. I have tried everything and the sound is to low after the loco is moving. Increasing the acceleration knob raises the volume temperarly but not very much and then fades off to almost no sound at all. If this problem was fixed with a patch I would give this Trs2010 an awseome A+ as everything else has been fixed including very smooth frame rates and good draw distance since the last Sp3 update.
