The subject matter of this blog is the Steel Industry and Railroading. Most of the posts deal with my attempt to model an integrated steel mill in HO scale, however, there will also be posts on real railroading and the real steel industry as well as other industries, and for that matter, general topics, that interest me.

ERIE DUNMORE CABOOSE BUILD, CONTINUED

DIGITAL FABRICATION - G-39 and G-38 Ore Jennies continued.....
The first G-39 was completed a few weeks ago. The photo above was from a test run on the Cherry Valley O-Scale layout. The white car to the right is the prototype G-38. The G-38 was the original PRR home built “modern era” Jennie. 1000 of the G-38s were built in the very early 1960s, soon followed by 2000 of the G-39s and G-39As. Much of the two cars are identical, with the exception of the additional 18” of height on the G-39s, the absence of steam lance portholes, and the much larger, pusher bumpers. The G-39 was built coincidentally with the emergence of taconite pelletized iron ore. The 70 ton rating of the G-38s couldn’t be realized with the lighter taconite. With the higher sides, the G-39 could carry the full 70 tons of ore. In the Penn Central era I’m modeling in O-Scale, the ore trains were a mixture of both versions of the car. I hadn’t originally intended to model the G38s, but for prototype fidelity, I changed my mind. Some of the laser cut files need to be adjusted and parts added or eliminated, but overall, much of the work had already been done, and the assembly was similar. The first G-38 is complete, painted, and partially weathered. I need to do some final weathering with oil paints and chalks and it will be good to go. At this time, I have about 24 G-38s and 39s under various stages of construction. The ultimate goal is around 45-50. Again, the laser cut parts, the laser drilled holes, and the laser alignment marks, makes assembly easy and fun. I have a number of other O-Scale projects of similar nature underway - an Erie Dunmore Caboose, a 60’ tank car, an 85’ TTX piggyback flat, and a Seaboard Pneumatic whale belly covered hopper. I’ll be posting about these occasionally, under the Digital Fabrication heading. All these cars are being built from scratch, with the intention of production of multiple cars, using digital fabrication to speed, simplify, and add precision to their construction. They are being built of a variety of materials, primarily plastics, and using a CNC router, a laser cutter, and multiple 3D printers.

STEEL MILL MODELING AGAIN, SORT OF.... G39 PRR Ore Jennie
I’d mentioned in one of my more recent posts, that I was attempting to model the PRR G-39 ore jennie in O Scale 2 rail, using a combination of traditional scratchbuilding techniques and digital fabrication. This is the car I am talking about -
The PRR built 1000 of the G-39 ore jennies in the earlier 1960s. They were to augment the thousand car fleet of G-38 ore jennies, that PRR built around 1960. The underframe, general construction, width and length of the G-39 was essentially the same as the G-38, however, the G39 was 18” higher. The extra height became necessary with the emergence of taconite ore. Taconite pellets were lighter and, because of their rounded shape, there was more air space within the load. The G-38 ore jennies were maxing out in volume, but not weight with taconite. Adding 18” to the car, increased the amount of taconite that could be carried, up to the weight capacity of the car. Some other improvements were made, notably, the oversized bumpers at each corner of the car. These bumpers were to minimize damage at the ore piers by the narrow gauge pusher cars.
Overall, the G38 and G39s were successful as purpose built cars. They were four or five tons lighter and significantly shorter than the hoppers the PRR had been using to haul ore. They had no bottom doors, meaning they could only be unloaded using a rotary dumper. They were used in service between PRR ore docks in Cleveland and Philadelphia, to the inland steel mills, including my favorite, Bethlehem Steel. Both the G38s and the G39s survived well into the Penn Central and Conrail Eras.
I am modeling the Penn Central in O Scale, roughly 1968-1976. How this all started was the purchase of two Alco 630 locomotives. The big Alcos were concentrated by the Penn Central in and around Mingo Junction, specifically for use pulling mineral trains to and from the steel mills. I thought a string of these cars would look great behind them. The only trouble with this plan, was that this car was never offered in O-Scale (it was in HO). Looking at scratchbuilding 40-50 of these cars, I realized the laser and CNC were going to be important tools, to produce exactly identical parts, allow for the use of tabbing and slots to align parts without measuring tools or squares, etch markings in the plastic for part locations, and my personal favorite, and you will know what I mean if you have ever built a resin kit, laser cutting/drilling 95% of the holes for the grab irons and other wire parts.
The car floor is .125 acrylic. The car sides, rim, steps/ladder verticals, coupler mounts, and underframe parts were made of .060 laser cut acrylic. The ribs were CNC cut from .100 styrene. There is also some .020 styrene laser cut parts, as well as .020 laser cut polybacker for much of the detail. Additionally, there is a mix of Evergreen strips and structural members used, along with wire, and Grandtline brake parts. I’ll get into the actual development and construction of this model in more detail in a later blog or YouTube video.
This is the first completed car - technically Version 5.0. There were some very minor corrections made and construction of the first ten cars of Version 6.0 are underway. Looking at more prototype photos while designing and constructing the model, I realized that Penn Central ore trains were a mix of G-39s and the older G-38s. The ratio was typically 2-1, with the 39s being the more prevalent car. Being that the G-38 is similar or identical in many aspects, a slight redesign of the CAD files enabled me to make the G-38 also. I still have to work out the ladder, end details, and the 32 steam lance portholes. Despite this cars simple appearance, it is very difficult to model, especially the ladders and end gear. I believe this is because you are dealing with sloping sides, ladders that joint on the corners, and partially rest on poling bumpers, that are themselves extremely angular. I hope, as I build more, these elements go faster.

CORONAVIRUS MODELING
Well, now that I’ve aired the dirty laundry, and as the boys from Monty Python say, “always look on the bright side of life”, there is an upside - more time for model railroading.
I think in my last post, I talked about my expansion into O-Scale. I joined a local O-Scale 2-Rail club last winter. The Cherry Valley Model Railroad Club has been located in the basement of the Grace Episcopal Church for 56 years. I had never been much of a club person, preferring to do my model railroading in my basement, alone, or with the help of my son. I’ve been presently surprised, and have been having a fun time with a great group of model railroaders. Having a specific meeting night every week has more or less “forced” me to play with trains - not a bad thing. With owning your own business, there always seems to be something you could be doing, especially when your shop has months of backlog, and it’s easy to just work more hours and forget about the fun things in your life. With Cherry Valley, I almost always get in three to four hours of model railroading a week. Sometimes its just running trains, sometimes working on the layout, and plenty of times just shooting the shit about trains, etc. Those of you who know me personally, know I’m pretty skilled at the last item.
What about steel mill modeling? Unfortunately, I haven’t worked on my layout much - why? Besides the time issue, honestly, it’s covered with O Scale cars and locomotives that I am building, painting, decaling, and weathering. To be fair, I went a bit overboard gearing up for O Scale, and have purchased at least 90 cars or car kits and probably a dozen locomotives over the course of a year and a half. I’m also doing what I have never really done in HO scale - for each locomotive or car, I’m painting, decaling, weathering, weighting, coupler height adjusting, decoder installing, before it gets brought to Cherry Valley. As most of you know, my basement is really small, so the only place I can set my rolling stock is on my HO Steel mill layout. O Scale cars and locos are twice as long, high, and wide as H.O., but that also mean four times the volume. I’m building a work room/ O Scale shelf layout in an old garage attached to my house (not really a garage - 7’x20’) When this is finished, I’ll be able to move all my work up there, and also have space to properly work on my large HO steel mill structures.
Moving on I am going to try to update this blog more regularly. If I go back in it’s history, the times I was most prolific with the posts, were also the times I did the most modeling. I’m also going to post some of my O-Scale modeling in this blog. The techniques and methods are transferable to any scale. I’ll title the posts with O-SCALE EXPLORATIONS, so if you don’t want to read, you can skip. I’ve posted photos some of my O Scale freight car weathering projects.
Everyone stay safe and healthy.
