I have a Premier 3-rail 2.0 Lackawanna Train master, that was packed away in it's box, I ran today. I got it for Christmas, in 2011, and it's only got 28 scale miles logged on it. I was very impressed with this model... in many ways. The sound file is one of the best I've heard; especially, the prime mover...
Recently, I got a scale wheels 3.0 Train Master(MTH) - so I thought I'd compare their sound files, today. The 2.0 Lackawanna smokes the 3.0 CP's prime mover sounds - basically, it just sounds tougher... a better bottom end. I was a bit surprised MTH didn't have as good sounds, in their more expensive scale wheels model.
The 2.0 sound package is great, in the Lackawanna; MTH seems to have done a better job with it...
