[quote]QUOTE: Originally posted by philnrunt JimZ, in Z scale, how big is a DD? [/quote] Hi Phil (is there someone there named "Runt", like a dog, I hope? :) A DDA40X, at 98feet 5inches at the extremities of the front and back of the body for the prototype (not including the couplers), is 5 3/8 inches in Z scale (1:220). It can negotiate curves of a radius of at least eight inches, but it looks horrible with the body hanging out over the outside of the curves that much - it looks better on curves of at least 10, preferably 12 inches in radius. As you can imagine, you can get a lot of railroad in a little space with Z, with 12 inch radius sweeping curves! I'll post pictures when I show off this loco for the first time in public at NTS in Seattle in July (it looks pretty ugly right now without any paint, decals, horns, grab rails, etc.). More to come in response to further interrogation from otherZ - gotta go eat din-din, or go hungry (and it's Marie Callender's restaurant discount dinner week - pies are only $5.99, too! YUM! [:p] All Z BeZt, Jim
