Whoops!

Lesson learned: Sheet styrene of 0.05" thickness is too thin.

It has almost no step transitioning from my existing street across the gap to the movable station segment, but is not stiff enough to hold its shape with color applied. I need to rethink this transition and move away from the idea of papering over the gap with thin styrene sheet. Instead admit there's a gap and dress it up the best I can.
