Sorry but I don’t have any good shots of the track-work leading to the paper mill. If you look at the above photo at the open space formed by the track looping inwards at the far corner you can see the space where the mill sits. The twin tracks that disappear behind the building and cross the mainline are the leads from the yard to the plant tracks. Those Those tracks were not placed at the time this photo was taken.
Here is a picture showing my Oregon Western Lines layout with a number of the Walthers' kits that I have used and modified (in many cases).
