HO-Scale GP-18 crosses trestle

An HO-Scale CNR (Proto 2000) GP-18 crosses over a 28" long, scratch-built trestle, with a short freight, on my shelf-layout. It's heading (on the mainline) towards my main yard (where it can be seen on my other video, passing through my main yard). This is still a work in progress, especially in the valley area that the trestle spans. Lots of trees and scrub are needed! More details about the layout on the video uploaded a few minutes earlier.
