I'm glad I finally decided to jump in on this conversation.
This railroad I'm planing will be 1953 north/central North Carolina so a Lumber and Paper facility is part of the plan. From this thread, I can see I have a lot to learn. I look forward to taking a look at the Yahoo group when I'm at home (IT Nazi's block so much here at work).
Here's a silly question... what is the difference between pulp processing and making paper? Are there industries that turn the 'scraps' from logging into 'pulp' to then be sent to a paper mill? Silly me, I always thought 'pulp' was simply wood chips.
Also, PVC from Home Depot would yes make a good source for 'large' pipes but for smaller ones you might consider Plastruct.com as they have scale valves, etc.

"Pulp" is the fiber from wood. The small diameter logs and wood scraps that have no timber value are, nevertheless, made up of wood fiber held together with a natural glue called lignin (sometimes also spelled lignen). The Lignin is what give structural strength to the plant cell walls and makes wood hard. In a mother nature equivalent to using fiberglas, the tree is composed of wood fibers glued together with lignin.
The first step in making paper is to obtain the wood fibers (also called wood pulp) from trees; the fibers are then pressed together and treated with different compounds to control the strength of the paper, its whiteness (or other color), etc. Getting the 1/4 -inch fibers out of trees involves grinding the trees into wood chips about the size of matchbooks. From there, different mills approach the process differently, but the basic choice is using refiners - like large grinders, to reduce the chips to fibers, or using digesters, which use acid and steam under high pressure to cook the chips and remove the lignin. What remains is pulp fiber (it looks like fluff cotton, but brown). This is rinsed and bleached (if white pulp is needed). The pulp fibers are then sent to the paper making process to be finished into paper.
Some paper mills make their own pulp, others get pulp from mills that make only pulp, and then make paper out of it. The whole process uses lots of raw materials and chemicals - great for a model railroad!

Thanks for the clarification.
"WaxonWaxov" was my Star Wars Galaxies character about four years ago. He started out as a "Teras Kasi Artist" which is the SWG equivalent of a Karate man, hence the name. Later I used the name in Word of Warcraft and a bunch of other forums.

Looking forward to seeing your latest plan!
I think i got the main building planed out. its on a backboard but it is still 7 inches wide by 3 1/2 feet long. the plan is to make it from parts of 2 ho scale walthers paper mill kits.
That's a good size - 3.5 feet works out to about a football field in length for HO scale, and production and/or storage buildings can easily be that size in a mill; one paper machine can be more than 100 feet long. Having that building 7 inches out from the backdrop will give impressive dimensions to the main building while implying it is even bigger! Have you see the HO scale Rumford, Maine paper mill on the yahoo paper mill modelers website? The builder used the same strategy you are using; most of the production buildings are against the backdrop and include components of the Walthers Superior Paper mill, but the overall effect is of a sprawling industrial complex with many buildings, many smokestacks, lots of piping, many chemical, fuel and process tanks, and space for 30+ HO scale freight cars. If you haven't seen it, take a look - it might give you some ideas!
I'm anxious to see your whole plan when it's finished!
The link to the Providence Northern railroad layout, at a club in Warwick, Rhode Island, is:
http://www.providencenorthern.com/
Check out the photo page and the paper mill under trackside industries.
Here is my design! The layout it will be attached to a n scale Bend Track layout at Model Railroad Shows. Bend track is all about bending in different directions. This will be the center peninsula of the layout. It is made up pf 4 modules total. A T-module that is 4 ft. wide by 6 ft long. This connects me to my dads part and his friends part. A 4ft by 4 ft center module. and 2 modules that create a 6 ft by 6 ft baloon at the end.
Because of the fact that my dad and his friend use dc and i use dcc you will see some interesting track work on the T-module. This track work lets me me run dcc on the b line on my modules and routes the b line for them to the other side of the T-module. Because of this all my switches are off the b line. I have a double cross over between the A line and the B line because at home all the tracks will be powered by my dcc units. There is a backboard down the middle of the peninsula spliting my paper mill scene on one side and my navy scene down the other side.
To Get the feel of the size of a paper mill i am using a good number of ho buildings. I added some conveyors in the pic but i am shure wonce i am constructing it it will have many more than what i put in the drawing. For this n scale paper mill i am using alot of the stuff i been collectin for my Ho Paper mill like:
Parts of 3 ho paper mills, Parts of the ho valley cement,Bags of Addon ho tanks, pipes, and conveyors, just to name a few.
On the Side in my navy section i am using my HO Pier and Ho pier Terminal for the same purpose for the dock.
Most of the main line tracks have been layed down on the modules so far. I want to have all the track work and as many of the buildings of posible done by Sept. 26 because that weekend is The Green county model railroad show.
Here is a link to the design

Hope you enjoy the design

A large modern pulp and paper mill covers vast areas and has complex and massive equipment that challenge the space constraints that are normally available to modelers . It would be similar in scope to modeling a large oil refinery. A creative approach will be necessary and research would be required. One approach might be to develop a switching railroad with staging. Another might be to have most of the facilities hidden (off stage). To model all of the basic pulp and paper operations would be a challenge but, if one concentrates on some of the structures themselves such as the paper mill and warehouse, it might make the task a little easier. Bear in mind that a lot of chemicals are delivered and the chemical operations in the pulp mill and digester areas resemble chemical plants and have complex piping and processing tanks that are difficult to model. Another consideration is the location of the mill. Southern mills have very open operations whereas Northern mills such as those in New England, Scandinavia and Russia are quite enclosed and easier to model. If one models an integrated pulp and paper mill it would be easier to just model the paper mill and hide the pulp mill. As described in this thread, there are many mills that are just paper mills and the pulp is delivered to them. Modeling just paper mills would be a lot easier but would reduce the volume of incoming tank cars. I will look forward to seeing more of this industry being modeled. Modeling in N gauge would make things a lot easier. I'm afraid though that I will have to stick with my saw mill modeling.Peter Smith, Memphis
You must have had an intersting job (though I travel fairly often on business and am increasingly less than fond of that aspect of work. It sounds like you traveled a lot!)
The sprawling size of pulp and paper mills demands every compression trick in the book, regardless of scale. I worked at a pulp mill in the Pacific Northwest that covered a 75-acre rectangle; about 900 x 3600 feet. A full 1/87 HO scale model of such an installation would fill an area of 10.5 x 41.5 feet! Even a museum probably wouldn't have room for such a model, let alone a model railroad (even a club!) Still, modeling just key areas of the mill could give the impression of the sprawling, chemical-heavy industrial process, as is accomplished beautifully by the Providence Northern's model of the Rumford, Maine Boise Cascade paper mill.
I'm interested in any and all approaches to modeling pulp and paper mills!
