Laid the last of the inner mainline track today. Following that I ran temporary power leads to the bridge and successfully ran locomotives around the track. There is one turnout that the Gunderson well stack cars don't like - the cars hit the turnout throw - but otherwise the look works well. I kinda suspected the Gunderson cars would not work on the inner loop with the tighter radius curves. Fortunately, I can still run the cars, it'll just be more of a challenge to get them in and out of the main yard.
No pictures today, but both the SW-9 and an 4-4-2 Atlantic traversed the track.
The only fault...I forgot to install the automatic uncouplers on two sidings. Fortunately, its a relatively easy process to backtrack and fit them to the track.
