Tunnel 30: The End of the Tunnel District

Just as Tunnel 1 is orphaned from the rest of the Tunnel District, so to is Tunnel 30. Located in Rollins Canyon, this final tunnel is a last gasp of the climb though the canyons to get to the high mountain valleys leading to the Moffat Tunnel.

After departing Pinecliffe, the mainline runs through some mountain settlements, including Pactolus. In this area, South Boulder Creek wanders int he valley and supports multiple small lakes and ponds near its channel. But once again, the valley closes in, and a short winding canyon has to be navigated to continue the climb. After crossing South Boulder Creek on a bridge (MP 38.6), the mainline enters Rollins Canyon. South Boulder Creek navigates the canyon with two sharp curves. The railroad follows, but has to use Tunnel 30 to make the first curve before following the canyon through the western curve.

To the west of Tunnel 30, South Boulder Creek was relocated to eliminate 2 bridges. I decided to retain the bridges in the plan, simply because I like bridges. In my mind, they add to the feel of a mountain railroad.

Pactolus and Rollins Canyon Track Plan

My plan faithfully includes these elements and should provide a sense of scenic separation between Pinecliffe and Rollinsville.
