When. First made the plans for Portland it included another wharf track. It never got put in because of restrictions to the control panel. I have been working on an acceptable solution and finally came up with the modified plan. I moved the turnouts to the Piggyback tracks to left and placed the missing the wharf track to the right and used a crossover. My tracks ended up being longer than original.
The below picture shows the wharf track in place. This track will eventually curve out toward the aisle.
Each track for Chase Transfer is about 1 1/2 cars longer than before and will give me some room for scenery.
The new panel ready for installation. The main difference is spacing and the one new siding.
