Thanks to all for looking at my post and thanks for the comments.
Here's a closeup of the tank farm. The vertical tanks are made from pill bottles shown in the next photo.
The lip at the opening was sanded off on the belt sander. The plastic easter egg was cut down to make the
tank dome. A little bit of putty and paint completes the tank. The pipes are made from solid wire which was
salvaged from a defunct flourescent fixture ballast transformer. The horizontal tanks were made from diabetic
test strip containers glued together at the open ends. The tank supports were made from a wooden paint mixing
stick you get when you buy paint at a store. Leftover structure pieces were used for the ladder and walkway.
The pump house was cobbled together from styrene scraps. The fire extinguisher is a piece of barbecue skewer
chucked in a drill and one end filed down to make the top. A piece of #24 solid wire was used for the hose.
The shack is a cardstock download available at the Rail Modeller Austraila website. It was printed on regular
paper which was glued to cardstock. The roof was made from thin foam sheet whch I got at Hobby Lobby.
It was weathered with white chalk.
The above photo is one of my favorite scenes on the layout. A plastic model of a Big Boy emerges from a
tunnel. The portal is made from would scraps with a light coat of drywall compound painted concrete color. The
mountain is styrofoam covered with drywall compound. The track bumper behind the white tank is made from
flextrack ties and styrene sheet. All the track bumpers on the layout are of the same construction. The little tuffs
of grass at the front of the Big Boy are pieces of scotchbrite pad.
The above photo is a wire & cable factory which is my first scratchbuilt structure. The cable reels are plastic
sewing machine bobbins wound with cable lacing cord. The parking lot is concrete colored paint which I
selected by taking paint chips at Home Depot out to the sidewalk to match the color. After drying, it was
painted black and then immediately wiping most of it off with a paper towel.
