One part of the hobby that I REALLY enjoy is planning my new design each year. I spend 3 or 4 months just coming up with designs until I "hit" on something that I consider a must do.
I prefer paper and pencil when designing and planning my layout each year. For some reason, even when I worked in IT, I seemed to think better with pencil in hand.
This is the lower level track plan. the red is my PW 2343 while the inner black is my Blue Comet:
The upper 2 plateaus: the bigger one is 4'x10' and the smaller front one is 4'x5'
Planning the lower lever scenery. This also helps me determine wiring schemes. The 2 big "blank" areas are where the 2 plateaus are so there's no scenery under them of course.
Upper level (plateaus) scenery.
Determining lockon placements along with isolating blocks for the preferred method of wiring DCS.
The different colored sections are each individual block. the 'X' designates center-rail dummy pin placements.
