"Double your pleasure... Double your run."

Hasil gambar untuk model train for beginner Obviously if a modeler with a single deck layout is unhappy with separation and run, he must revisit the multi-deck concept. I say 'revisit' because I had given it consideration prior to beginning this project, but ultimately decided against it.

I have all but memorized Tony Koester's book on the subject and have visited and operated on some great ones. But I've never quite been a fan of the multi-deck for my purposes. At least I don't think so. I was heartened when I read of Marty McGuirk's dismantling of his upper level and especially related to his reasons why, which he mentioned in his blog, and expounded upon in an issue of Model Railroad Hobbyist.

I do like having one deck at optimal working, viewing and operating height rather than two at compromised ones. I dislike having to worry about more lighting... and I do have to acknowledge the modest ceiling height with which I'm working. But most of all, I just prefer the look, or presentation if you will, of a single deck.

But I enlisted the help of Bob Sprague, planner extraordinaire, in a what-if, why-not scenario. I figured it's worth the beer that he charges! Hang on, here we go.

This is the upper level. The multi-deck layout plan is a point-to-point one with two major LDEs per deck. The helix forces a change in direction in this out-and-back format and is of a 'backbone' or 'spine' style. The spine serves as both support and backdrop and the loops alternate between running on the inside and outside of the spine. This alternate format provides about 8" of vertical separation so the outside loops can be sceniced. Radii are 36" and 28" respectively. Ted DiIorio details this type of helix on his blog.

This is the lower level. The depth of each deck is staggered to maximize viewing, eliminate congestion and minimize scenicing. The distance between LDEs in this plan is generous. Mainline run increases from about 90' of the single deck to almost 220' for the multi-deck.
 
To be fair to Bob, he urged a plan that utilized the helix for staging areas with return loops and consistent direction, but it required a two-level gate across the 24" entry which is a feature I really dislike. But that's it for now... a lot to think about. Wouldn't mind getting some viewpoints from you all out there! Do comment.
