Info re Bachmann K-27 from owners

I'm beginning to lust after the Bachmann K-27 but have several concerns that you pioneering owners might be able to help me with. I am in a small town in the mountains of Colo and do not even have access to a hobby shop to look at one. From reading the threads, it appears that Bachmann has now solved most if not all the serious design issues. 1) Am I correct on this?

Unfortunately, I have several curves on my layout where I had to use 8' diameter track. 2) Will the K-27 easily take 8' diameter without larger diameter transition track?

Finally, I had to quit using a Bachman Annie on my Aristo stainless 4 years ago as I am convinced that some sort of electrolysis occurred between the cast drivers on the Annie and the stainless track: required serious cleanup every 10 minutes of operation to the point of serious frustration. (I had no problem with the turned steel drivers of my LGB locos.) Of course, that was just on DC, not DCC which I am presently using. 3) Does the K-27 have power pickup thorough the drivers or throuch a 'shoe' a la LGB? 4) Are the drivers of the K-27 cast rather than turned? 5) Has anyone with stainless track experienced unusual black deposit on stainless while using the K-27?

6) Any recommendations of DCC decoders for ease of installation on the K-27?

Thanks for your input, guys!

This is a fascinating discussion for me since I'm planning on buying one at the 2008 NNGC this next week. (there are no hobby shops within 3.5 hours of my home). I've often harassed Bachmann for their choice of prototype (and occasional quality issues), but I think the K-27 is a benchmark in 1:20.3, especially considering it's excellent price and prototype-specific detail.

Having said that, and recognizing that we large-scale modellers are a diverse group, I do find it hard to imagine that anyone would want to the the K-27 at twice the prototypes maximum speed (that's 43 real feet in 10 seconds - 5280 feet/minute divided by the scale of 20.3 scale/the divided by 6 to convert from minute to 10 seconds). I would *much* rather have good control and range at slower speeds then run a loco 2 times what the prototype ran at. And I suspect that I'm not alone in this belief. Stan Ames said it's hard to guess what max speeds the modelling public wants (again remembering how diverse we are). But I think the prototype itself offers some basis to make that decision - a 1:32 F or E unit should be able to operate at some decent scale speeds. Not so much for a 1:20.3 NG steam locomotive.

BTW - I'm not arguing with Stan Ames in any way - he's not the guy who made the decision. Just giving my 2 cents, if it's worth even that.... :)
