I learned a loop or two gets old fast, even a loop and figure 8, which what we had and at 8 or so my brother and I got boarded even with the layout down with Christmas tree in a mountain stand was up from Christmas eve to a week after New Years.
Therefore I decided if I build one it will have lots of things to run and Play with. I build a two oval layout, center oval had a homemade turn table and figure 8 and outer loop had two crossovers to the inner loop. Also both loops were relayed to allow two trains to run on each loop. I also had lots of operating accessories. The layout was on the floor for only about two months from before Christmas. So it was not a full time layout and model trains were not my only hobby.
The layout was expanded to an L with two track diagram control panels and has three LW transformers and has 31 switches and a Wye. It also has 12 operating accessories including a operating gantry crane and turntable and is not a boring layout.
Bottom line is expand and add more things to operate, run, switch, do, anything more than watch two trains loop around. I have things to do like dump logs to a car and unload them at the saw mill which produces lumber. I can dump coal from the coal mine into a car that can dump at the coaling station, but do not have a coaling station to dump coal into a coal tender yet. I have my gantry crane to unload Mercury space capsules and it can unload lots several containers of various commodities.
My layout is 44 years old and I enjoy improving and modifying it just as much as running it. It is never finished and never will be. Just last year I added the Wye after thinking for years I could not get a Wye to fit. The Wye also made train operation much more challenging and also allows moving a train from the inside loop of the main train board to the outside loop of main train board to the outside loop of the new train board and also changing the direction of the train from CW to CCW. I also added a homemade municipal water tower for the city and naming the city Spencer, NC on the tower. The year before I added extra ties between the three 027 metal ties for the whole layout. I also am still building homemade cars and adding homemade accessories recently including converting a cheap Lionel log dumper to a remote operated log dumper. Improving the layout keeps me and it fresh and keeps up interest. Also share the layout with friends and acquaintances to keep interest up.
The layout is not all that big being Main Board 11ft – 2 in X 5ft - 9in, New board, making the L at the bottom of picture, 7ft – 6 in X 4ft – 7 in
