A New Cold Storage Building

Although my layout is not complete it is at that stage where I am making changes to existing scenery and structures. I do not plan any changes to the existing track plan, however.

One of the latest changes is the replacement of a shallow relief warehouse with a shallow relief cold storage building.

When you first enter the layout room the straight ahead scene is the view block that separates the two sides of the peninsula. Along both sides of this view block are rows of shallow relief buildings.

Between a grain elevator complex and the recently modified Scheu Manufacturing Company was a single story, run of the mill warehouse of a tilt-up concrete design. This was a carryover structure from my previous layout, made from styrene sheet and shapes. Because the structure always was located at a high viewing angle I never needed to install a roof on it.

Shallow Relief Warehouse
 
I wanted to replace this structure with something more interesting so I measured the space and decided a Walthers R. J. Frost Ice & Cold Storage building would easily fit. Too easily. The long side of the building would leave too much space between its neighbors so I calculated that adding a section from the other long side would lengthen the building just enough to fill the space.

Lengthening R J Frost Building
 
Another issue was that I already have an R. J. Frost Ice & Cold Storage building just a few feet down from this area so the shallow relief version would have to be modified to look a little different from its brother. The solution came from a layout I had visited in Atascadero, CA.

Bill Obermeyer's HO scale Obermeyer Ranch Railroad has been featured on the last two layout tours I organized for the Central Coast Railroad Festival. Bill modified both the R. J. Frost Ice & Cold Storage building and the Walthers' Red Wing Milling Company by lengthening the structures and adding tile roof sections, among other modifications. I like the tile roof idea as I had done this with the shallow relief Elephant Packing House using Plastruct tile sections.


Bill Obermeyer's Model
 
So I added a wall section to my R. J. Frost Ice & Cold Storage building, added a small rooftop shed and a large air conditioning unit and I was in business. This building sits along a spur that doesn't quite reach the last two loading doors so I closed off these doors under the scenario that the spur originally was connected to the nearby main track but now it is connected only to unseen track in the other direction.

To make the tile roof standout I painted some of the individual tiles lighter and darker shades of the terra cotta acrylic craft paint I used. I had done this to the Elephant Packing House but this time the differences between the tiles was too extreme. I was able to decrease the visual differences by giving all the tiles a very diluted wash of the original terra cotta paint.

Differences Between Tiles Too Extreme
 
I don't have a company name for this structure but I probably will designate it as a branch house for a major meat packer. These were still common in my 1956 era.

Finished Structure
 
So what is a branch house? A branch house receives sides of meat and lesser portions of animals slaughtered in the major packing plants and further processes these for the local wholesale trade. Facilities for smoking meats and sausage manufacturing also could be found in branch houses. On a model railroad a branch house is a good industry for receiving meat reefers. As these were owned by one major packer or another, only one packer's reefers should serve a branch house.

Freight Cars: Metal Wheels Equal Lower Center Of Gravity

From time to time I present a clinic at conventions on tuning up freight cars. One of the points I cover is ways to lower the center of gravity on a freight car. If nothing else this reduces the chance of a derailment.

Many of us have older freight cars with plastic wheels. A major consensus in the hobby is that metal wheels roll better, wear better, and attract less dust and gunk than plastic wheels.

Another advantage is that metal wheels lower the center of gravity and add weight.

Consider a typical HO scale blue box Athearn forty-foot boxcar or equivalent Model Die Casting, Train Miniature or Accurail car. Using the NMRA's Recommended Practice for car weight (RP-20.1) such a car's ideal weight is calculated at one ounce plus one-half ounce per inch of length. That works out to about 3.75 ounces for a forty-foot car.

The stock Athearn plastic wheels with metal axles weigh .15 ounces. This is only 4 percent of the recommended overall weight for the car.

As you can see by the attached slide, various brands of metal wheels weigh two to three times this amount.
 
 

As a percent of the recommended overall weight for the car the various wheel brands "weight in" as follows:

Proto2000...........8%

Kadee.................9%

InterMountain...12%

So, would you rather have 4 percent of the car's recommended weight down at the wheels or 8 to 12 percent?

Tank Car Weathering

Weathering tank  cars requires some techniques not used on other freight cars. Here are some tips from Bruce F. Smith on weathering tanks cars. Keep in mind this is just one of many approaches and these mainly apply to older, oil haulers.

1) Start with an overspray of weathered or grimy black.  These cars got very grimy from smoke, dirt, dust and road grime and were rarely washed or repainted.  This also dulls the markings.

2) Add additional grime from spillage in the dome area.  I like oily black for this.

3) Add bearing oil grunge to the bottom and ends of the tank where leaky bearings on the car, or neighboring car would have spun oil out onto the tank and frame.

4) Add a rust wash to the edges of the tank bands to indicate where expansion and contraction have rubbed the paint off allowing rust.  Also rust the truck springs.

5) Add fresh spills with gloss paint.

6) Add appropriate placards and chalk marks.

And Tony Thompson also has some illustrated recommendations:


Here are some prototype tank cars weathered by the hand of man and nature:
