Intro Orchard Yard Rimrock Tumwater Mining Co. Methvyn Coldwater Cascade Timber Co. Mt. Brynon Willow Grove


The Tumwater Mining Co. electrified branch line climbs above our mainline and heads 22 miles south into the heart of the central Cascades in search of rich ores.

The east end of Rimrock.

Tumwater Mining Co. branch climbs above Rimrock.

A pair of electrics climb the hill.

They enter the picturesque east tunnel just out of Rimrock.


A short distance west of Rimrock the line emerges from a tunnel and crosses a high level curving trestle. Built by PC&E bridge engineer Dave Dudman, this curve has been dubbed "Dudman's Curve", by a few PC&E engineers who failed to observe the speed restrictions wisely imposed by management! High on the mountain above the main you can see the Tumwater mine before we plunge into the damp darkness of Tumwater Tunnel at the summit of the Cascades.

On the other side the cross a wooden trestle high above Dudman's Curve.

Snow and rocks often pelt the line.

The Tumwater Mining Co. terminal.


Meanwhile, back down below, a Milwaukee freight train crosses Dudman's Trestle on the mainline.

A lower view of the amazing bridge.

Our next stop is Methven Summit.
