I am finally getting trees onto the layout. I purchased some new trees and am also using the trees salvaged from the Rochelle layout. Below is a video and some before and after pictures. Came out pretty well I think.
Plaster forms have been added to the Des Plaines River crossing. Below are pics of the plaster cloth installed on screen wire. One additional benefit that I have found of using plaster cloth is it is much easier to install trees. The dried plaster is much thinner and most trees can just be pushed into place. The blue masking tape is for protection of the track while painting the plaster.
This last picture shows the low tech method of protecting the signals before painting the plaster.
Here's the scene painting and applying ground foam. The bridge still need a lot of work such as painting, weathering, walkways and lots of graffiti on the piers. Of course, the area will also need trees and ballast on the track.
