After expanding to the full table size I built the second track, which climbs and descends twice per lap between the upper and lower levels, and includes a long bridge to a hairpin on the shelf along the wall. Lap times are typically 13-16 seconds.

The digital layout places the pit lane right after the start/finish line. I have not yet decided on the best locations for the lane changers, but there aren't many choices. 3 are shown in the initial layout. I'll probably put the 4th lane changer on the Long Bridge, and I may move the one I initially put in the Twisty Bits up there with it.

Lane 1 is 27.31 meters and lane 2 is 26.18 meters. I am still making modifications, so the differences between lane 1/2 lap times below are a lot more due to the date they were run than to actual differences between the lanes.
