I'm brand new to the hobby and am sure relieved to find some help. The files have already answered many questions I didn't even know I had. For now my lay-out is the dinning room table but I am clearing room in my shop for a 3X18 ft. bench. My immediate question is about my new Bachmann N 2-6-6-2 Mallet, it runs about 1/3 the speed of my 4-4-0 and my 4-8-4. It's beautifully detailed and looks great running (slowly). Is there a problem with this loco or am I just expecting too much. Is it possible it's running at scale? (the 4-4-0 American runs like a slot car!) Thanks, Dave R.
