A new scenario pack for the GN Budd RDC is now available. In this three-part scenario of 240 minutes total play time you'll be the engineer of the old GN RDC, pressed into service by BN in 1971 for an inspection tour of Stevens Pass for some new employees. You'll run eastbound from Delta Yard to Wenatchee, but heavy traffic and your train's low priority will make things a bit difficult.
You can download the scenarios on the Golden Age of Railroading website. Please note that they require quite a lot of additional free- and payware equipment, it was not possible to model the colorful early BN consists without them.
Below are a few screenshots from the first part of the trip, Delta Yard to Skykomish:
