I've started ballasting the yard. I have eleven switches, and some good stretches of track, so this will take a little longer. Unlike the mains, I now have to consider the placement of the station, REA building, freight house, etc. So I'll guess as best as I can on the placement of the structures, and I'm sure I'll need to make adjustments as I go. I'm going to leave the yard ballast black to show the grimy condition of the yard during the end of the steam era, and will add some extra weathering to the area afterwards.
