 I'm modeling the transition period, early diesel, late steam period. The layout I started back in the late 80s started out as an article out of an MR. And it met a certain amount of criteria that I wanted in my next layout because this is actually my second layout that I built. I wanted a switchback logging type railroad. And so I started with a basic plan. I expanded it a couple feet each way. If I look at the major construction over the years, I started out with phase one that was basically the plan out of the MR. And then I looked at the basement and said, well, I can bring something around the corner here. And I always wanted, well, I had the roundhouse and turntable for my old layout. And I wanted to incorporate that in some way. So I brought the layout up and I raised it a little bit in elevation and did that section. And then I got with a switchback, really, it's fine in an idea, but to operate it, I like to watch trains running through scenes. So I incorporated the tails of two of the switchback legs and made a reverse loop, or not a reverse loop, but a continuous loop out of those so I could run that. And that was basically phase three. On the first few phases, first three phases, basically I used Code 100 Atlas. I was very happy with that. I did incorporate a few Pico turnouts to fit situations. The last phase, the engine facility, I used Code 83 Atlas trackage on that. If I was to do it all over again, I think that would be the track that I would use on everything. And then phase four was after accumulating locomotives and over the years, I wanted to have a larger, expanded engine facility that I had, but I really didn't have room in this room. So I punched through the wall and designed the layout on the other side of the basement. I have dreams of expanding more on the other side, but technically the layout of the other side, I don't think it's very conducive to layout. I got doors that I'd have to get by and windows and whatnot. But I'm happy with what I have. I use a NCE DCC system. Well, when DCC first came out, it was sort of in this area of Grand Rapids. The club had it, Bruce Chubb, which I did a lot of work on, his layout had it. And it was just, to me, was a natural step to go into something that I was familiar with already. I have quite a few solid locomotives, both steam and diesel. I have a few of the structures are lit. I have some street lighting on the layout, Boulevard lighting. I guess my favorite part of the layout would be the branch line engine facility. I built a scratch, built an engine house. And I was able to incorporate the shea that I had built when they first came out years ago, the MDC shea. And it's just a place where I think if I were to be, that's where I would like to be.
