Well, the original GG&N was completely dismantled for our move. While most of the track survived, along with the electrical equipment, some of the wood (the legs in particular), and of course the locomotives and other rolling stock, it was time to end its tenure. As I'd mentioned in the past it was simply trying to do too much in too small a space. This appears to be a thing with Atlas track plans; they seem to regard 18" curves as normal and 22" as broad in HO, while for the rest of the model railroading world, 24" is considered average in HO and broad doesn't really kick in until around 30". Atlas plans are fine if you either A) only want to run small cars and locomotives in relatively short trains or B) can significantly enlarge them.
The latter is what's going to happen! I mentioned before that I though Jerry's 6'x11' space would be vastly superior for the GG&N, simply by making curves broader and the grades less steep.
We did not get the house with the 9'x12' storm cellar. I liked that house a lot, but we got one I like even more! - fortunately, real estate is not terribly expensive in south Texas, so we were able to find a house of a pretty good size, and more importantly that had the space well laid out. This included a HUGE upstairs living room. I'm told that most of it originally should have been an extra bedroom, but it was left wide open, giving the kids a nice big play area - and me a section for railroads! This is the upstairs family room - at the moment its still the dumping ground for stuff we are tying to figure out what to do with.
This front section, by the windows, is approximately 8' deep by 20' wide - perfect for the rebuilt GG&N, while still leaving the majority of the room open for the kids. The plan I actually came up with will actually only come out about 7' for most of the width anyhow.
A shot of the space from one wall to the other. The plan will come all the way out to the edge in that far section, then it will cut in about 6 inches at the point 8' in front of the edge of that window, for a depth of 7'6" for the other 15 feet stretching towards the camera.
This is the plan I drew up. It may be hard to read, but the idea is basically the same as the original GG&N - 2 over-under figure 8s more or less parallel with each other, with 2 major crossover tracks from one to the other.
In addition to expanding things to the size available - all of the curves on the major lines except one are 30" radius, one curve on one crossover is going to be 28", some of the curves in yards and sidings may be 22-24" - I added a long passing track on one side of the river, and added a second small yard on that side. The tiny spur at the base of the larger yard was moved farther away from it and lengthened into a much longer spur.
Finally, a long distorted "oval" of track was added around the outside of the entire affair to allow a third train to run continuously. The main purpose of this is for when I eventually get some passenger cars; their length and the high speeds passenger trains run at mean a nice, smooth oval with less rising and falling will probably give them better performance.
The 2 squares are cutouts to pop up and be able to reach all parts of the layout. I am going to build this one a little lower than the last; many model railroaders like their layouts close to eye level but I want to be able to reach easily, and I want children to be able to look at it easily too.
The large trapezoidal shape at the bottom is the control area. That will go in front of the window. My original plan was that there would be a long space in the center where you stood and the layout went around you, but my wife did not want the table to be actually up against the windows, so I created that trapezoid to keep it back. That's where the control panel will be, so one will need to duck under the center of the layout to get to it. This trapezoid was what led me to go with a revised version of the GG&N. I also promised my wife I would hang a curtain from the room side of the layout so as to keep the bench work concealed.
I plan to take this one a lot slower than the last one. I kind of went crazy to just "get it running RARR!!" with the original GG&N and that probably led me to a lot of problems. I'm also MUCH more aware of the pitfalls of little details now, and I won't be dealing with such extremes of tight curves and steep grades. Plus, I need to spread the expense out. In particular, I want to change to digital control, but that's going to cost some, so I really don't plan to have anything going until at least August when my birthday rolls around.
More pictures to follow! I'm off this week for the holiday, so work is probably going to start!
