Good call. Never though of that but that was just from a first layout section. Then he changed it to the 2nd one without using the vertical short tract sections.
But using no layout and just laying the pit sections on the floor and aligning the single lane sections side by side as they need to be still there was a 1/4 inch difference. Yet it's disappeared in the final layout.
What is an explanation for the difference in length between the pit and the single tracks in these 3 pics?
First pic is the left side, 2nd pic is the left, 2nd pic is the right side, 3rd is the whole pit section.
