The Rio Verde Line

Built by Ted Brandon


Ted Brandon was known for many years as one of the premier Nn3 modelers. Recently Ted decided to switch to On30 and set about recreating his Rio Verde railroad in that scale/gauge. Ted has been kind enough to share his new On30 layout with us on this website. So without further ado, I turn this over to Ted:

"Having been active in model railroading for over 60 years, I had gradually moved down the scales from O-Gauge tinplate, through S, HO, TT and finally to N, but with a twist: Nn3 was so challenging that I could not resist it. I worked in Nn3 scale for over 20 years, ending that period as editor of the "Nn3 Handbook," the bible for that scale. My pride and joy was a scratch-built twin-motored model of the Uintah 2-6-6-2T Mallet in Nn3, all of 3-1/2 inches long!"

"Once I reached 80 years of age, I began to wonder how long my fine motor skills and vision might last, so decided to convert my N/Nn3 Rio Verde Railroad layout to On30, a scale with easier-to-handle equipment. I intended to do this with a minimum of destruction to roadbed and scenery. Fortunately, my Nn3 curves had been pretty wide, but On30 curves on the same roadbed meant accepting a 16-inch minimum radius. This wasn’t tragic, since I had decided to limit my motive power to BLI C-16s and Bachmann 2-8-0s at the most."

"I was able to retain most of my scenery, except for making adjustments for the wider swing and height of On30 locos. My N-Scale pine trees, however, had suddenly become On30-seedlings, although the overall effect, especially with the mountain backdrop, remained good, in my view."

"The Rio Verde is built on framework ranging around three sides of a 24 x 15 foot basement. Except for two peninsulas extending into the center, the framework is supported by 1x4 braces extending at an upward angle from the joint of floor and wall to the front cross members. This method provides excellent strength while eliminating the risk of accidental damage from kicks to traditional vertical legs under a layout’s front."

Rio Verde Track Plan

"The layout features a single-track main line of about 150 feet, ending in a return loop at a small station with its own freight yard and a commercial facility. Altogether there are four stations on the railroad, each with one or more freight customers, including a coal mine still pending. At typical 12-15 MPH scale speeds, main line running time out and back can be up to 15 minutes."

"Train control is handled by a 5-amp NCE wireless DCC system with sound installed in all steam locos."


Rio Verde Loco #6 on powered 12-inch Turntable, with Arttista Operator at the scratch-built controls.


#6 taking water at the main engine terminal. The water tank is scratch-built, based on a coffee can, with coffee stirrers forming the tank. The sandhouse and coal facility are based on an S-Scale sandhouse kit, extended for coaling.

#6 passing a three-way turnout on its way to head its passenger train.

#6 starting its 3-car passenger train in the layout’s "Brandon" main station, an Atlas O-Scale kit (station named for self).

Train passing the Bricktown Brewery complex and yard. The buildings were constructed in relief form, fitting against the layout wall.

Train crossing a MicroEngineering steel viaduct, originally used for the N-Scale standard gauge Rockland Railroad, which then connected to the Nn3 Rio Verde Railroad.

Train approaching the "Marksburg" Station, a Cornerstone kit. (Station named for my son).

Train crossing "Dead Man’s Gulch" on what was once a Kato N-Scale Warren Truss bridge. It was turned upside-down for use by On30 trains.

Train approaching truss bridge of two combined Atlas HO bridges. The bridges were sliced down their centers, then widened by inserts. Four angled ends were cut away and the bridge ends were joined to form a single, longer bridge to cross the gap over two tunnels and a river sluice.

Train crossing HO Scale MicroEngineering steel viaduct. Each tower took a whole day to assemble.

Train crossing original N-Scale wooden trestle built from two combined Heljan kits. The bents from both kits were mixed to obtain greater length.

Train crossing N-Scale Arnold steel bridge.

Train crossing MicroEngineering steel viaduct.

Flanagan Station (station provisionally named for a helping friend).

Train returning to "Brandon" main station.

The 2-stall Engine House is a kit produced by Deerfield Laser. Ed Fillion is an enthusiast manufacturer of laser-cut building, boat and railroad car kits of high quality.

Some intricate trackwork at "Morrisette" station (named for a helping friend).

The Rio Verde is on a tight budget, so the boss's office is sized accordingly. He is a classic car enthusiast.

Diesel Switcher #7, with a cut of two cars backing up is guided by a trusty Arttista brakeman hanging from a ladder.' This is the only non-steam loco on the Rio Verde RR. It is a Boulder Valley Models superstructure kit on a Bachmann DCC-equipped 44-Tonner model.

Grandma and Grandpa are patiently waiting for their train, while a young worker begins loading a baggage car on the station's stub track.


Nn3 Versus On30

The Nn3 loco is a casting of exact size. On30 equipment is 33 times the volume of Nn3 counterparts.

Editor's Note: I first saw photos of Ted's old Nn3 layout in the Sept./Oct. 1998 issue of the Narrow Gauge and Short Line Gazette. His modeling in Nn3 really impressed me, and he had built a really beautiful layout in this scale/gauge.

I met Ted at several of Allen Littlefield's Mid-Hudson On30 meets and learned that he has switched over to On30. Later I found out that he had purchased an NCE 5 amp DCC system, same as mine. We commiserated via email about our lack of DCC knowledge and decided to share our experiences with it. Ted also mentioned that work was progressing well on his Rio Verde layout.

Sooner or later I knew that I would ask Ted for an article on his Rio Verde for the website. Well, here it is and I hope that you all enjoy it as much as I do. Ted has done some fantastic work on the layout and I thank him for sharing it with us.
