 I started right before the merger in 1968 and we've had various operating session schemes since then. I think we had one in 68 and then we moved up to I think 1974 and then we were about 1980. Right now we're in like 86 or 87 and eventually we're gonna go to 1994-1995 since that way that's when the Burlington Northern ceased existence so and we'll start over again. Yeah we have operating sessions. We have a round robin group that meets here. We meet every Thursday night. I've done that for years and years. I have anywhere from seven to ten, twelve people depending on the night that show up. Typical operating session we run 45, 50 trains. I build a lot of engines, paint a lot of stuff as you go around the layout. Probably a third of the cars on here I painted. Most of the engines I've painted over the years. The control system we have is something that one time in Model Railroad they had an article and we've built four of those about 20 years ago already and I built four more here the last couple years so and they work nice. The geographic part of the layout right now is really from Lincoln to to Billings with the old CBNQ and then from the Billings on down to Seattle was old Northern Pacific and Great Northern and when we were in our 1968 mode that's how we operated. Those units would interchange up there in the Billings yard up here and go back towards Lincoln where the other stuff is run back and forth between one of my hidden yards which was Minneapolis and the West Coast. Physically the layout is is a complete double deck all the way around the layout. There are actually three or four other levels that you don't see that allow me to get trains in and off the layout as an interchange. But just basically you know one by four construction, cantilever off the walls. The reason that the various sections are the heights they are is the very first section I built goes over the top of my washer and dryer and that kind of set the tone for everything. It also allows me if you was over the other side I have three great big file cabinets underneath the layout that again that was set the height of it because they had to go on top that because I've got all kind of records that I have to keep over there. I didn't get too low on these because it's hard to see them otherwise. The lower levels over here are very convenient to operate out of a regular folding chair. You know there are nice heights you can sit here and operate everything and one of the gentlemen that operates for me that's the reason he likes to work over here because he can sit down and he rolls back and forth from one end of the layout the other and does his work and he you know has a good time. I like the parts that I've got the scenery done on. That's always been my really weakest point and I don't like doing it because it just so like where we're at right now if you look back down here most of this end of the layout is done except for a few pieces down through here and there's a big a big long area over on the other side that's probably 70 feet long that I have gotten done and when you run the trains down the hills over there they look real nice.
