Thanks for all your comments.  My primary purpose is being able to set-up some track on the floor and see the wheels turn.  Eight foot diameter track in a home is a stretch for most rooms.   I know the wider the turns the more realistic the train looks but indoors comprises must be made. 

I wanted to know if LGB R3 track/turnouts would work with the K27 (even though it is two inches narrower than the manufacturer's recommendation for 8 feet diameter circles) before I went out an bought some.   Udo evidently has had good luck with this so I think I will give it a try.  Does anyone have a better recommendation for sectional track?   

This is probably an old subject but I have a K27 coming.  It is my FIRST large scale model.  I have given myself an ice cream headache searching the web for info on modeler's experience with this locomotive on different brands of track/switches.  I know your specs say 4 foot minimum radii.  I am interested in using LGB 16000 (3 foot 11 inch) radii track with their 1600 switches due to their availability.   I will not rehash the different opinions/experiences I have read but lets say they are varied.  What does the Bachmann say?  Scotty

I am contemplating another narrow gauge endeavor.  I have no experience with Fn3 so please excuse this simple question.  ARE THESE LOCOMOTIVES TENDER DRIVE?   The description in your "Products" does not specify.  thx.
