15th anniversary of this blog

It seems hard to believe, but yesterday, December 11, marks the completion of the 15th year I have been writing this blog, with over 300 posts per year. In fact the post you’re reading is number 1852 in the series. It seems like an impossible number to me, but since this is something that my host, Google, keeps track of, I know it must be true!

At this point, I’d also like to mention that a few years ago, I posted a summary of my goals and intentions for this blog, and anyone relatively new to reading it might benefit from seeing what I have set out to do (see that post at: https://modelingthesp.blogspot.com/2021/02/the-purpose-and-uses-of-this-blog.html ) 

As I often do in these annual reflections, I reviewed the page view data provided by Google. In the first five years or so of the blog, my posts typically received 150,000 to 200,000 page views a year. More recently that has moved above 300,000 a year, in some years approaching 400,000 page views. That itself is amazing to me.

But there’s more. Last year on this anniversary my total for all the preceding 14 years was just above 3 million page views. This year it’s risen to well over 4 million. Yes, over a million page views last year, for a single year. 

I well understand that “page views” include web crawlers and other internet denizens visiting a web address, though without any actual interest in the content, And to be sure, taking 15 years to get to 4 million page views, even if it’s mostly non-content visitors,  is nothing compared to an internet “influencer,” but still, it seems like a fair amount for a model railroading blog. 

As has been true almost since this blog began, I receive comments and questions about the content, some of them via the comment function that Google provides, so that other visitors can see those inputs and my response (if any), but also, increasingly, by personal emails from people who I suppose don’t want to make questions or comments public. That’s fine, and many times I realize I hadn’t been clear or didn’t go far enough in a description. These interactions are interesting and welcome to me. 

My layout continues to host operating sessions. I am among the considerable number of layout owners who do host such sessions, and like many of them, I feel like the main reason I brought the layout near to completion was to host such sessions. When visitors operate the layout and all its equipment, the layout is functioning as I envisioned it years ago when I was still in the planning stage. You can’t ask for more than that from a hobby.

I can’t resist showing a scene fairly typical of my operating sessions, from a couple of years ago. Shown below are Dave Falkenburg (left) and Bob Hanmer (visiting from Chicago), operating at Shumala. Here Bob is serving as the engineer while Dave is the conductor in carrying out the switching work in this part of the session. This session was back in 2023; you can read about it at: https://modelingthesp.blogspot.com/2023/10/layout-operating-session-no-85.html .

I continue to find operation to be a really interesting part of model railroading. Partly for that reason, I strongly welcomed the introduction of the new Achievement Program in operation created by the Operations Special Interest Group (SIG) of NMRA. I wrote a post describing that program (see: https://modelingthesp.blogspot.com/2025/08/a-new-achievement-program.html ). 

The foundation of such operation by modelers is, of course the prototype. So photographs like this one (Conductor Charles Martin in Southern Pacific caboose 684, Class C-30-1, in the 1950s: Stan Kistler photo) continue to intrigue me. When we modelers act as conductors in an op session, we aren’t provided with the captain’s chair or a desk, but we work our waybills very much like Mr. Martin is doing here.

Beyond those considerations, I must admit upon reflection that I continue to enjoy and even relish nearly every aspect of this hobby of ours. Except maybe wiring. My several posts entitled “Electrical wars” probably bear witness to that. (You can use “electrical wars” as a search term in the search box at the top right corner of this post, if you’d like to read a few.)

On that topic, I well remember a cartoon that once ran in Model Railroader, showing two guys with halos over their heads and little wings on their backs, looking at a small layout floating on clouds. One is saying, “Wiring? What wiring? This is heaven, remember?”

Operating sessions #106, 107

The latest two operating sessions on my layout were on December 7 and 8. By and large, they followed my usual format and content, with only a few changes in the program, though with extensive changes in car locations and car movements (which of course were directed by waybills).

On Sunday, Dec. 7, I hosted four operators and an observer. Most of that crew is shown below, with, from left, Robert Bowdidge, Leo Pesce, Alex Craghead (nominally the observer), and Miles Callan. They are standing at Shumala getting organized to begin the session; Leo and Miles are holding throttles. 

The other crew member was Jason Schoenmann. He and Leo began work at Ballard, with Jason conducting, but later in the session Robert took Leo’s place when the crews switched places. Here Robert is conducting, with Jason at right, operating at Shumala.

 A feature of this session was the inclusion of one of Southern Pacific’s new piggyback flat cars (service began in June 1953). From the earliest days of that service, trailer flats were mostly inserted into the “Overnight” trains of black box cars, but for some months occasional “extra” movements did occur in scheduled freight trains. That's what I depict here, in scheduled eastward train 916, passing Shumala.

Both the flat car and the trailers were 3D-printed by AJ Chier, as I mentioned in describing my modeling work on this car in a series of posts (see the final post at: https://modelingthesp.blogspot.com/2025/06/sp-piggyback-part-7-finishing-flat-cars.html  ). 

The following day I hosted another session, essentially a repeat of the previous day’s car movements, with a few exceptions. One crew was Jim Radkey (left) and Bryn Ekroot, who you see here at Shumala . I enjoyed watching these two work together. 

The other crew was Seth Neuman (left), here conducting at Ballard, and Lawrence Crowl. Seth is such an experienced conductor, that it’s always worth watching how he organizes and carries out this kind of assignment. 

These were fun sessions, with crews quite busy. Being that many of the visitors are experienced operators, I did set up pretty full workloads, and all was done in good season, with few errors. Nice work, and of course fun for me, mostly in seeing the layout come alive to be operated as I intended it to be.

My brass foundry in Ballard

From time to time, I post short descriptions of the industries on my layout, what they do, and how they form part of operating sequences. Today my subject is the Union Brass foundry in my layout town of Ballard. As a physical metallurgist before retirement, and who did thesis research on copper and brass, this is an industry I understand.

The building itself is built without much change from a Classic Miniatures kit, including the signage on the building front. But because the building front is oriented perpendicular to the layout edge and thus a little hard to read, I added the larger sign over the loading dock. This dock, by the way, was enlarged from the rather narrow one in the original kit. The model of the building represents a wood false front made to look like stone, something common in the century preceding the one I model. 

From the other side, you can see the furnace room addition. Also evident below is the near proximity on the right of the Jupiter Pump & Compressor facility. The idea here is that the brass foundry came into existence to supply brass plumbing parts for Jupiter.  

Part of what’s interesting about this building is the loads that are shipped in and out of it. Inbound may be bulk copper (and the foundry makes up the brass composition by adding zinc) or brass bar stock. Plumbing fixtures are shipped out, not only to Jupiter but to customers elsewhere. Sample waybills are shown below.

At left you see an inbound load of copper bar, shipped from Cananea in Mexico. As often happened at the Southern Pacific’s port of entry at Nogales, Arizona, Spanish language waybills were replaced by SP ones and the previous SP de Mexico waybill number shown (you can click to enlarge). The bill also shows that the car cleared customs at Nogales. At right is an outbound shipment bill, with a Transcontinental Freight Bureau weight agreement stamp on it.

Many loads arrive and depart in ordinary box cars, but an option is an occasional foreign box car, and I mean lierally foreign, from Mexico. The waybill shown above for an ASX car is the result of a custom decorated model years ago by Bev-Bel for a car owned by American Smelting & Refining (Asarco) in Mexico, and accordingly with dimensional and other data in metric as well as English units. 

I shouldn’t leave the impression that raw materials for this foundry come only from Mexico; the heart of the copper and brass businss in the 1950s, which I model, was in Connecticut, and this foundry more commonly receives loads from Bridgeport Brass (in Bridgeport) or Chase Brass & Copper (in Waterbury). 

This industry is different from others on the layout, in part because though it is a small structure, it also produces small parts in a simple casting process, and thus can realistically output carloads of product. So often on layouts (including my own) our models of industries are far too small to do the work we imagine them doing. This one is at least a little better in that regard.

Trackwork wars, Part 17

The ongoing saga of the track replacement at the lead to my town of Santa Rosalia continues. In the previous installment, I was satisfied with my new track right at Santa Rosalia. You can read that account at this link: https://modelingthesp.blogspot.com/2025/11/trackwork-wars-part-16.html .

With some careful adjustments of the gauge in a few places, I was able to successfully operate one of my diesel switchers back and forth, which of course is what happens in an op session. This operation was essential to verify before doing any more work on the track (note the areas with missing ties below). 

As isn’t visible above, both the MP1 switch motors were now disconnected, and since the throw bars of the new switches are located differently, obviously new “trenches” would be needed for their linkages, along with the MP1s being relocated to have the throw rods perpendicular to the track. You can see this pretty clearly below. Both motors have been “unmoored” from their previous locations. 

But before restoring the linkages, I needed to do more painting of rails, as I mentioned in the previous post (see first paragraph, above for link), and I did so, completing work on both new switches on the main line to Santa Rosalia. I also added ties where they were missing, using old surplus tie strip or individual wood ties. 

The next step was to restore the more important of the two linkages, the one at right in the photo above, which controls  the Walthers curved switch. That’s because when structures are put back in place, it is behind the storage tanks of my Richfield oil dealer, thus not accessible for manual operation. In the photo below, the new trenches are cut. 

Finally, the linkage was reconnected and the correct motion of the throwbar verified, for the Walthers switch. This may have to suffice for the upcoming op session, unless I find time to fix the scenery surfaces. But at least this part is now working.

It is frustrating to continue to work the same problems in the same area of track. Hopefully this time it will yield a more permanent result. Thanks again to Jim Providenza for his help with a major part of this effort.

A superb new John Signor book

Continuing his remarkable series of books about the Southern Pacific, John Signor has just published the latest, this one about the San Joaquin Division. As always, the richness of photo coverage across a lot of years is very impressive. Below is the dust jacket. 

The book is published by the SP Historical & Technical Society at $90 (visit https://sphts.org/product-category/books/ ). It’s an 8.5 x 11-inch format, and is truly a large book, containing 586 pages. It has many of John’s characteristically excellent maps, of which I show a single example below pages 306 and 307). Spanning two pages, not all of it can seen in this quick scan, but it should be enough to portray the kind of information and detail in most of the maps. (You can click to enlarge.)

I counted 105 maps in the book, many from SP, including SPINS maps, but quite a number in John’s distinctive style. All of them add considerable depth to the information.

The volume is a treasury of action photos from all eras. John has freely mixed color and black-white images, wherever they logically fit. And I should mention that John has taken the opportunity to expand, revise and correct the some of the material he published years ago in his fine book, Tehachapi (Golden West Books, San Marino, 1983). One superb image from Robert Hale is shown below, depicting the westward San Joaquin Daylight at Tehachapi Loop in the early 1950s, with helper 4352 on the point. 

The book extends to the last days of the SP, and includes such latter-day information as the Palmdale Cut-off, along with many of the abandonments and dismemberments of the division. An example image from more recent times is this eastward mixed freight near Delano in the early 1970s, passing vast vineyards on the right (John Bergman photo).  The trio of SD45 locomotives is headed by SP 8834. Delivered through the late 1960s, the SD45s from EMD would dominate the SP locomotive fleet thereafter, with a total of 356 units in all. Those added up to more than 28 per cent of all the SD45s that EMD would produce. 

I confess to not being an objective reviewer, as I have long admired and greatly respected John’s books about the geography of the SP. But this one takes a back seat to none. Not only SP enthusiasts but all kinds of railfans will find innumerable facts and photos of interest. I can’t recommend it highly enough.

My Zaca Mesa winery

In my layout town of Ballard, there are two wine shippers, the larger of which is the Zaca Mesa winery. This is a large structure, made from a resin kit for a power house that I bought partly built, and then modified and completed. Here is the lid of the kit box, showing how the kit was intended to be built.

The upper photo above shows a receiving building at the right, for hopper cars of coal for the power plant. Since I wasn’t building it as a power plant, that annex was superfluous for me. I made it into the shipping building for a lemon packing business, and located it in a different town, Santa Rosalia. I modified the various openings with roll-up doors, especially the open archway on the end.

I also didn’t think the triple plain smoke stacks in the original power house kit were suitable for a winery, so replaced them with ventilators from my stash. More obviously, I changed the roof of the Magnuson building by giving it a tile roof, creating more of a California look.

In the foreground above, you can see my addition of a platform for loading tank cars (for details, see: https://modelingthesp.blogspot.com/2017/02/tank-car-loading-platforms-part-3.html ). A close-up of the platform also shows the building sign, shamelessly copying a real Zaca Mesa winery in Santa Ynez (Santa Barbara County); here’s their website: https://www.zacamesa.com/ ), though I didn’t copy their logo or building.

Lastly, the building has some loading doors, which are useful to me as the place that cars other than tank cars (more about that in a moment) can be loaded. The third photo from the top in this post shows a Class XT car (house car body with internal tanks) being loaded at these doors. 

The role of this winery in layout operation is conveyed by a background post of mine, about wine as an industrial commodity (see it at: https://modelingthesp.blogspot.com/2012/02/wine-as-industrial-commodity.html ) . There’s also an article in Model Railroad Hobbyist, in the issue for May 2023 (introduced at: https://modelingthesp.blogspot.com/2023/05/my-column-in-may-2023-model-railroad.html ). 

Wine grapes would be brought in from nearby vineyards, crushed and fermented, then aged to the desired degree. They can then be shipped out in bulk (in ordinary tank cars or XT cars) or packaged in bottles. As my modeling year of 1953 precedes widespread use of insulated box cars, un-iced reefers would be used for shipments of packaged wine.

I have always enjoyed having this industry on the layout, in part because it looks large enough to justify rail shipping at frequent intervals. Far too often, we model embarrassingly small industries, then regularly ship carloads to or from them. This one, at least, avoids that problem of scale.

New SP Shipper's Guide, Part 2

In the preceding post, I showed the general features of the new Southern Pacific “Shipper Guide,” for 1952. For me as an SP modeler, it's a rich trove of potential operating information. You can read that previous post at: https://modelingthesp.blogspot.com/2025/11/a-new-sp-shippers-guide.html . In the present post, I want to illustrate specific features.

In the previous post, I showed an overall map of the Las Angeles Terminal District, with 16 zones identified. Here is an example of one of these zone maps, Part 1 of Zone 16 (Zone 16 extends to Burbank Junction, where the Coast and Valley routes diverge), on page 70. Why choose this map? It’s the literal area where I used to railfan the SP as a youngster, walking down Sonora Ave. to the tracks.  

Each siding has a number. As the Guide states, the drawings are not to scale, and do not indicate locations of switches, gates, doors or impaired clearance points. Each number of course corresponds to a user of that siding. The users are listed on an accompanying page. Shown below is page 69, the list that goes with the map above. Note that some sidings have multiple businesses on them. I remember watching the Burbank Local crew working these multiple spots. 

An important part of the new route guide is that there is considerable information about the route card number assignments, which would permit a person to operate a layout using route cards only. I earlier showed an SP listing of the meaning of its route card numbers in the Oakland and East Bay areas (that post is here: https://modelingthesp.blogspot.com/2016/05/route-cards-10-southern-pacific.html ). Below is one of four pages listing the Los Angeles tag (route card) numbers. The upper part here shows zone tags, that is, for the zones mapped as described above. Below are “road tag” listings, for outbound cars.

But even more interesting to me is a listing in the back of the guide. It contains all the industries in the guide, in alphabetical order, and tells you its track number. But in addition, it gives you the tag number (i.e. route car number) for that industry, and at the right, lists the size of the industry spot (not the siding) in cars. Here’s one of the pages.

Amazing stuff, especially for a document nearly 75 years old, containing what you’d presume was long-lost information like tag numbers. As I mentioned, you could operate a switching layout entirely with tags, if you wished. That’s what a local switch crew would have been doing.
