The Sandquist Railway is a two level O Gauge layout that includes a helix with 081 and 090 radiuses, that takes the trains between the two levels.
We are modeling the end of the Steam engine and the beginning of the Diesel era. Think 1955 or so.
We are roughly modeling the Western Pacific railway from the middle of California to the middle of Colorado, passing through the Sierra Nevada mountains.
The Mountain that covers the helix is over 8’ tall!
We are using Atlas O track and with 56 switches.
Switches are controlled by Z-stuff for Trains DZ-2500 switch machines
