Overview of the Layout

It
took several attemps, but I was able to arrange the buildings to look
correct as possible
and also allow track to access each structure.
With all the switches, there was a lot of cutting and soldering of
track to.

This
is the area west of the steel mill. I wanted it to look very
industrialized.
Again, the tracks were layed to access all of the buildings.

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
half-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.

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.

A photo from my old layout in Maryland (2001 - 2019).
The town of Hyndman, PA. There was a lot of activity in this
small town.
The baseball field will be moved to another town on the new layout due
to available space.
I
am a member of the following railroad historical societies.
