Hello everybody!  I've recently acquired some Bachmann large-scale equipment.  I must admit, I don't need my 25-power glasses to work on it like I do my N scale!

I apologize if this has been covered before, or if it's too much of a newbie question, but I would like to know what scale this stuff is.  I see on this website it's called 'Large Scale'.  I've also seen it described as: 'G'; 1/20.3; and 1/22.5

Right off I need some new wheels and couplers.  Do Bachmann replacement metal wheels fit all of the rolling stock?

Thank you for your help!

If you're still looking, Minitrix (Aurora Postage Stamp) made a B-unit, dummy or powered, for their F-9. Some people called them F-7s actually.  They show up on Ebay quite a bit.
