A George Sellios Trick

As I've said before, I've downloaded hundreds of photos of George Sellios's Franklin & South Manchester layout to study for inspiration. I'm not one to follow him slavishly, but over the years, I've found tricks and tips from his work that I'm not sure everyone notices. In part, that's because his work has changed over the years.

For instnace, these days, he's more likely to download images from the web and incorporate them into his buildings. He also uses commercial building flats where he can, always dressed up in various ways. I started out with this project a year or so ago, inspired by him but with my own twist. It was meant to fill an otherwise empty corner spot:

I built the triangular mandrel from foamcore and sized it to fit the ghost sign image I'd found on the web. Ghost sign sites are great sources of details and ideas. Over time, I realized that Sellios adds two things, vents and climbing plants, to otherwise flat surfaces. I found some vents at the Rusty Rail site. I used them in combination with Blair Line fan vents, and then I added sme climbing vines on the corner:

Not all of his buildings are to the same stanard. Some are just blah plastic kits that he's just added things like roof entries, rooftop billboards, and old signs to. He sprinkles figures, vehicles, and junk piles around them to distract the eye. I don't want to make my layout an F&SM wannabe, but I like the effect yuu can get following some of his ideas.

Finding What's Lost

One thing I'm beginning to understand more clearly is that the freight cars I operate are items I enjoy in and of themselves, since they're often souvenirs of railfan trips, mementos of various sorts, or just tings I likd the look of. Thus I'm less concerned about whether they fit a specific era or layout concept.

I was running a switvch list in JMRI and discovered I couldn't find a particular car, WP 1442, where it was supposed to be, on Track 1 in Zenith. I looked all over for it, but as is sometimes the case, I just coudn't locate it. Luckily, JMRI understands stuff happens, and it allows me to remove the car from the train. I did this, but rather than reprint the switchlist, I just crossed out the car:

Naturally, life being life, I found the car right after I crossed it off the list and deleted it from the train. WP 1442 is a great favorite of mine. It's a 30-year old Roundhouse bulkhead flat with an N Scale of Nevada printed paper HO lumber load. I got both one day at the old Allied Models on Pico Bl in Los Angeles.

All's well that ends well. I caught up with the train, put the car at its destination by hand, and updated the JMRI file with the destination it was meant to have.

Replacing A Digitrax AR-1

A DCC auto-reverse unit allows operation under DCC to traverse reversing sections in wyes, reverse loops, and similar trackage without the need for manually reversing polarity in situations where rails of opposite polarity come together. They operate by sensing an electrical short in such a situation more quickly than a standard circuit breaker on a booster and reversing the necessary polarity before the circuit breaker sees the shot and trips.

I had a Digitrax AR-1 on a reverse loop for this purpose, but I was never completely satisfied with it. It was hard to set up, The AR-1 uses a " Tunable Trip Current Adjustment Screw" to adjust operation on a particular layout for whatever variables are involved. I found that when I first installed it, I had to fiddle with the screw to get it to operate correctly on my reverse loop.

On top of that, I was never able to get it to work with more than one unit in a locomotive consist. The first loco would pass into the reversing section, and once things were tuned, it would trip the reverser, and the single unit would run through the section. But when a second unit followed the first one in a consist, it would reverse the polarity again and cause a short. I don't know what the problem was, but fiddling with the adjustment screw didn't help.

I resarched the problem as best I could on the web, but i never found anyone talking about the exact situation I had. And from years as a computer tech, I don't have confidence in support lines. So I went looking for a substitute. It seems as though most people are satisfied with, or put up with, the AR-1.

Eventually I settled on the Tam Valley Depot Dual Frog Juicer, which is only slightly more expensive than the AR-1. The basic Frog Juicer works to change polarity on a single switch frog, under the principle outlined above: if it detects a potential short, it reverses polarity before the main circuit breaker can detect it and trip. The Dual Frog Juicer can be used to do this with two rails at once, so it's usable as an auto reverse unit. A jumper is provided that, when closed, will allow it to operate this way.

I swappped out the AR-1 with the Dual Frog Juicer this weekend, and after testing and some supplementary rewiring, it works fine, with single units and multiple units in consist. So I'm very pleased. I've used probably half a dozen Tam Valley products on my layout so far, with aboslutely no problem. No product defects, clear documentation, easy installation. Not every DCC supplier has this record with me.

I can use the AR-1 on a narrow gauge wye that will have only single steam locos operating on it, so I haven't really lost money.

Bringing The Malabar District On Line

The Malabar District is a pair of micro layouts arranged in an L shape in a storage room next to my main layout.

The section at top right I built, with a few changes, from the late Jack Trollope's Box Street plan. I did this about 15 years ago and ran it as a stand-alone until recently, when I built the shelf at left to connect with it. I incorporated Jack's original drawing into the plan above.

The curve at lower left leads to my main layout in the next room via a tunnel through the wall.

At this point, the district operates mainly with a local that runs from Malabar to Paper Box and back. One thing I discovered in the change from making Jack's Box Street a stand-alone into a part of a larger layout is that I've had to change the way it operates. The original design works from a sector plate at right, where equipment is loaded and the train starts and returns.

BBut considering the way the original plan is oriented, I had o connect it via the straight section at the other end, on the left. This left the sector plate with less to do, since the way freight that runs to Paper Box now enters and leaves from the left. After giving this some thought, I've decided to use the sector plate as a fiddle yard, a place to place and remove cars. Then as I gave this more thought, I realized that the way the funnel to the main layout is built, it can't handle high-wide cars.

So operationally, I've set up the old sector plate as a fiddle yard interchange for high-wide cars onto the Malabar District. I've tweaked the JMRI operating plan to account for this.

Here are some shots of operation with regular trains on the district.
