May 2015 Update
I have largely installed all the FrogJuicers to about 60 switches, DPDT switches to about 10 switches, and 8 Servo motors to 8 switches.

Here is UP 956 coming out of the city. Note on the right is the 4 track staging yard. From the aisle whilst operating most people would not see these staging tracks.
Here we pass the start of the freight yard.
Now we will take a freight train of automobiles around the layout.
BNSF 9762 about to leave yard with car carrying load.
Many of the locomotives have been speed matched and their roster catalogued in Decoder pro.
