Jigs and holders and gauges and whatnot are necessities for catenary construction. That thing with the plastic strip is a pole height gauge. The plain block is a wire height block/gauge thingy. The flat one on the track is a drilling jig that (hopefully) will guide correctly spaced and square mounting holes. The styrene sheet nestles the jig into the gauge of the track; the gauge will be held in place temporarily with a screw during drilling.

|The span bridges all primed with Rustoleum metal primer, which will dry for a week or two before further painting. Hats off again to Oberleitungsbaumeister Don Silberbauer of Model Memories for producing these showpieces--|
the bridges looked great in bare brass but they look even closer to real with this first coat of paint. The etched
brass lattice is truly delicate-looking, but still quite sturdy.

rubbed down with a wire brush, then with steel wool, and finally wiped down with denatured alcohol

Siting the Model Memories catenary span bridges--the first step of many in my catenary construction adventure! One lesson learned here is to plan better, because it was starting to look like the grade crossing and Mineral Springs flag stop might need to be rearranged (as in torn out and rebuilt). but I think I worked it out so that the flag stop will actually look more interesting , with a pole right there by the shelter.

The Dunes Junction flag stop is coming right along. From left to right: the a-building flag stop shelter, scratchbuilt from styrene and temporarily held together with drafting tape; a painted and decaled Walthers Cornerstone public telephone held in the clutches of a clothespin; and guard posts fashioned from Code 70 rail and painted an awesome shade of dull orange from a Liquitex spray can. Good times!

|Mostly finished and scenicked in. I built some footings|
for the crossbucks from styrene, which I then painted with
Floquil concrete. Aleene's Tacky Glue holds the crossbucks
down on the footings.
I decided to try my hand at some lighting effects to add a visual action to the scene. Busch 5934 US Crossing Signals had the look and the price I was looking for, plus they were 'ready-to-run' with a flasher circuit included in the package.
The Busch signals are pre-wired with hair-like magnet wire, and the circuit is in very small case around the size of large ice cube. Two leads connect to a 12-24v AC or DC power source. The magnet wire terminates into the circuit via binding posts that are secured by press-fit plastic pegs. Have never seen anything like this, but they work.
I like to test electrical things, and re-test them, and then test them again during all stages of construction and installation. I test-ran the circuit and crossbucks off an old analog power pack, and ultimately acquired a Radio Shack Enercell 15V wall wart power supply, which will now serve as accessory power for the whole layout. These Enercell wall warts can be equipped with a variety of tips, including a plain old set of test leads, but I chose an actual plug-and-socket arrangement that can break away easily when moving the layout .
The flashing crossbucks are controlled via a miniature SPDT switch mounted to the front of layout adjacent to the road. I considered but rejected a detector circuit (too expensive, too hard to install at my current stage of completion, and probably would be annoying on such a small layout) and DCC stationary control (too expensive and kind of complicated compared to direct control via a cheap and simple ol' switch). I wired it all up to easily accommodate an ITT crossing bell sound module, which will go in over the coming weeks.

Rick's work demonstrates what can be done with state-of-the-art heavy electric modeling--always a pleasure to see this awesome depiction of the heyday of New Haven electric operations.
