What are the best turnouts for a 2x10 shelf layout?    atlas #4 or #6 turnout?

My motive power are GP's and I have some 24,000 gallons  tank cars and  40' open hoppers.

It's been a while since we had anything worth saying about the Sudbury Division, but we can report we are still chugging away, though not with steam locos.  You may recall we were having issues with electrical pickup in our last installment (Tales from the Basin Part 2), and we had to work long and hard to get that under control.  Last summer we took every car off the layout and cleaned each of their wheels individually with cotton swabs and alcohol, cleaned all the locomotives and all the track from top to bottom.

I have heard about a product called "Jiffy Railer" being sold out of Arizona. The company is not a registered business in Arizona, I have not been able to find a website, person's name, e-mail, or phone number associated with this product. Does anyone have any experience with this company and product or is it just vapor ware?

Thanks

 Hey everyone, looking for input on how i can shrink the flanges on my n-scale sw1200 without a few thousand dollars in machining equipment.

Is there a poor man's way to turn down those flanges?
