Viewing some of the layouts here at the OGR forum, and elsewhere, including some lighter weight construction HO/N scale layouts at other forums and sites, I see that quite a few are on wheels, presumably to provide access to the back sides for layouts that are situated against a wall. Makes good sense...we can only realistically reach 30" -- or even less -- across the layout, and if there are no access hatches (which sure seem cumbersome to me), how else can you reach the rear of your layout unless you can roll it away from the wall to work on the back?
My question to any of you who've used wheels on your layouts (or are considering them for a layout yet to be built): What do you suppose might be the maximum length a layout could be if it's on wheels, and still be manageable to roll out for rear access...either to get underneath to work on wiring, or to work on the back side's track and scenery, or to get at a derailed train, etc.?
I have two different basement locations where I can locate a layout. One could accommodate a modest 4-1/2' or 5' wide x 14' long, pushed against two walls (so against a wall on both the entire back side as well as one end), or another slightly less desirable location where I could go larger and manage a 4-1/2' wide x 20' long with only the entire back side against a wall. The 14' long layout might be able to be on wheels (not that I'd go rolling it all around the basement floor, of course...just to access the rear for working on it). Doesn't seem realistic that a 20' long layout could possible be on wheels...too heavy to roll away from the wall, too much chance of the benchwork being stressed or bending when pulled on, etc.
Any remarks from from those of you who've worked with benchwork on wheels?
