This layout does something I’ve always wanted to do: create a Figure 8 for the Sky Train. It took two complete Sky Train starter sets to pull off, and incorporates all of the Sky Train accessories.
The #33931 Clock Station and #33926 Loading Station are actually fairly restrictive in how they can be used. If you want to have a train passing under them using the lower track piece then they need to be placed along curves in the Sky Train loop, and it helps to have the yellow struts on the inside. The Sky Train Support bases are large and this is the easiest way to ensure the lower track clears them properly. BRIO illustrates this, more or less, in their 2004 Sky Train foldout.
In this layout, I also did something new: I used squares of textured scrapbook paper to represent land cover for the whole base. There are four shades of green, two shades of brown and two shades of grey. This time I chose not to laminate (unlike my previous experiments with papers) since the textured surface provides more friction for the track.
