Here's another great video! Notice the prototypical speeds when the train is moving, this is one thing were layouts often fail, the trains are going too fast! Not in this case, very convincing and very smooth too. The only thing I would have liked to see a bit better is the acceleration, a bit too fast for my liking but once running, it looks very good. A nice example on how it should be done. The author is commenting on the sound difference on between a QSI and Tsunami decoder. While I can't comment on that yet, there is a difference audible, the GP20 has the Tsunami and sounds a little 'tinnier', it doesn't have the low end rumble of the other engines. I am wondering though if it has something to do with the speaker used, and the way it is mounted inside the engine, and how much space it has (on the F unit, the hood is much wider, so can have a positive impact on the sound, there's potentially more air to displace, which makes the low end frequencies more pronounced. (a bit like big or small hifi speakers )
