Does anyone have any comments on the pulling power of this unit? I have a 4% grade on my table and am curious if anyone has found any issues with it's power on such a grade.

Does this engine have the ability to produce smoke? Can anyone comment on how it runs and the quality of the sound.  thanks

New to HO, looking for suggestions to what type of track is best to use on my layout. Purchased A  Bachmann set with gray road bed. Have read some comments about derailing especially with Bachmann turnouts. Atlas makes a similar product called true track. Are these two interchangebale? Any thoughts?

I'm new to all this, purchasing 2  engine units a EMD GP40 and FT-A, both are DCC equipped. Can sound be added, if so, can you tell me what product to buy, are they difficult to install.

I'm purchasing 2 units, EMD GP40 and EMD FT-A. Can sound be added to these, where can I find what will be compatible?
