As a geologist, David knows very well that this is a gross generalization. Granites in the real world range from as coarse as he describes or coarser, down to very fine-grained  with individual mineral grains the size of a grain of sand (full-size sand, not HO scale). These may require a hand magnifier to distinguish the grains. But I certainly agree with his point, that crushed real granite to the side of HO scale ballast will not look right.

It may seem like using the real material provides maximum realism, and for very fine-grained materials like coal, this can be true. But granite is a rock in which the individual mineral grains are 1/4-1/2 inch in size. When crushed to the size of HO or N ballast, the result is a bunch of grains that are all composed of bits of different single minerals. Prototype granite ballast had a uniform hue, crushed granite ballast is speckled with grains of multiple different colors, depending on the source rock. 

And Charles is right about decomposed granite, which is highly weathered and looks nothing like fresh crushed granite from a quarry. Paver sand around here is frequently a fairly strong brick red color and contains a wide range of grain sizes.

The newer F&C one piece castings seem to me to be as good as any. Problems with their decals. They look like they're from the 60s-70s. I used the recommended NSC decals on this model. I covered the resin sill steps with ACC, hope they stand up to operations? If not I can replace them with DA ones...Which I'm not fond of. Picked the trucks out of my 'truck drawer' don't know who made them.
The kit came with both wood and Allen Wood running boards. Looking at the photos in the instructions it appeared only the DT&I car had the AW boards, so I used the wood one. When I asked on this list about better decals I was given a link to PRR specs. There it said it should have the AW board. I happened to look at the label on the box and it said X37b w/ Allen Wood running board. So...I popped off the wood one and replaced it with the wood one  ;  ))

Yes, the Yarmouth car is quite successful at
depicting this effect. I'm surprised to see the
1/45 blt date. Seems early.

Re: Granite shipped in an open hopper

Gary, not sure that this was regionally true, but the ERIE had limestone ballast for much of the main line.  Limestone ballast over the years tends to solidify because rain dissolves it, and it forms a very hard foundation for the tracks.

 

Schuyler

 

 

Don't forget that most railroad ballast (at least in the Southeast) is granite, and granite is used as the coarse aggregate in asphalt and concrete paving.

Good afternoon,

Fwiw, I have Yarmouth 220 sill steps for my in the pipeline F&C X37's.  I'll need to snip off one vertical piece, but will end up with a metal part with the support angling toward the coupler.
I believe I also have Plano etched Allen Wood running boards, but misplaced them in my last move, relegating this to a back burner project.

Cheers

Tim is right. The glossy new paint magnifies how you can see the waviness in reflections. A dirty car will be far less evident. The PFE engineer I interviewed told me that when their first welded cars were made, they insisted that a few were re-done to try and eliminate the wavy look. It’s hard to do, and they then discovered that as soon as the car got dirty, it was difficult to see even if you looked.
That said, better welding technique can certainly do better than that C&O car.

Archer weld seams, or very skilled use of a hobby knife blade. :-)

I think this C&O car was the subject of an article in a magazine. It did not have the classic "PS-1"
underframe, but instead had a standard AAR welded underframe.

Ah... here it is --

Mainline Modeler June 1994 pp.66-69 modeling article from MCKEAN kit, builder photo #15153,
and color model photos (Greg Martin)

Of course, now you can start with the Kadee pre-1950 PS-1 model, which is better than the McKean car.

A few years ago Jason (Owl Mountain) had his 3-D printed 'alligator' cylinder guides (or whatever
they are called) for his SP 2-8-0 on display at the RPM in St Louis -- they were made in shiny metal
and looked as good as any I've ever seen on a brass model. I wonder what the manufacturer's print
cost would be to make a whole locomotive body (not counting all the R&D investment).

Tim, it is already being done. Dan Shepard from Australia has been working on a C&O H7 2-8-8-2. It is on par to the latest brass models.

I have also seen several N-scale shells for converting existing movements to other prototypes. Another gentleman has done an On3 shay for the Mann's Creek Railway. The resolution on the latest round of printers now allows for prints that are on par with injection molded parts.
