Greetings,

I'm thinking of starting my On30 layout.  I've collected several Bachmann locos and some rolling stock for this, and my space will be roughly 4x4 feet.  The locos I have are the Bachmann 2-6-0, Bachmann T-boiler, Bacnmann 0-4-0 diesel and a Bachmann 2-8-0.  This layout would be mostly using mining cars and various other Bachmann freight cars.

What's the minimum radius that these trains can utilize?

And what brand track do people find the best for a "realistic" narrow gauge look?  Normal HO track seems a little strange for this scale.

Thanks!
