Latest work completed:
Not as much getting done in the warmer months with all the outdoor work to do.
Installed Caboose Industries switch throws to all main line switches
Next work to do:
Continue work on the bridge to the blast furnace
Install switch throws to two mainline switches that are not accessible adjacent to the track.
Overview of the Layout
Latest view of the steel mill area.
Three of the switch throws in place. I painted the ends of the handles to easily
see which direction the switch points are in.
Green: for aligned normal
Yellow: for between mainline tracks
Red: for diverging route off the main
For the background behind the steel mill, I wanted to make a large rolling mill.
It actually didn't cost much money to make - it was made out of 3/8-inch foam
board, aluminum foil for the siding, and sand paper for the roof.
All the details were parts left over from other buildings.
This is the west end of the rolling mill. It is 99 inches long.
Added the lighting above the doors. All are LED lights.
Because the mill stretches between McKeesport and Pittsburgh on the layout, I didn't want to
name it National Tube Works, or Edgar Thompson Works. I will use the more generic
United States Steel - Mon Valley Works.
The sign was taken from a photograph found online.
This view shows the background interior that shows up with the layout room lights off.
The bridge to the blast furnace work is in progress. The piers are completed.
The deck bridge on the right is only beams at this point.

Track charts showing the location of switches, tunnels, bridges, elevation, grade, and the interlockings and blocks.
Some of the track is not totally accurate due to space, but all the tunnels and bridges are properly located.
Train room dimensions along with the approximate dimensions of the layout.
The size changed a bit as I was laying out the track. The room is approximately 755 sqft.
