Set 3: Marsh Trestle, Glacier Valley

Marsh Trestle is a curved, wooden trestle built across a marshy area in George's Gorge. Railroad maintenance engineers are getting ready to make repairs to one of the platforms on the trestle where one of the fire barrels has "mysteriously" fallen off the platform, into the muck of the marsh below.

Glacier Valley is a busy junction point on the railroad, with tracks converging at the bottom of the 2% grade along Willow Creek and across the South Forks River, and then separating into the double-track tunnel portal leading to Bucky's Crossing.
