Originally the layout was built 4 feet by 4 feet. But the curves proved too tight, the streets were too tight, the city blocks too small, the sidewalk corners had to curve to clear the intersection tracks... it just wasn't working. But just by adding another 6" to each side of the layout made all the difference in the world. So the intersection was cut out of the old cramped layout and then spliced into the spacious real estate of the new 4'6"x4'6" layout.
Time to put a car on the track and take her for a spin! Yeah, sure its "roundy roundy". But after all this time were finally rolling! I'll take "roundy roundy" over "display, display" any day. And when it does finally get old, well...
With the mainline continually advancing forward it wasn't long until all four blocks were in. Now the cars can dance the "Cloverleaf", the "Double Untwisted Figure 8s", or even 4 simultaneous "Roundy Roundys" and everything in between!
Pretty neat, eh? Yes sir! Pretty darn neat!
