Plus a set of castings for a 7 1/4",  7 1/2" 2-foot gauge Rangeley Lakes truck

I have drawings for many of these parts. Click here:   Drawing List

The drawings shown below for trucks and other assemblies are concept drawings intended to aid my design of the castings. They are not complete construction drawings and serve only as guides to actual construction.

Car Parts


I have castings for three styles of arch-bar trucks.   In all of the following tables I will show my part number, what is included and the number of part numbers to order to build one CAR (usually two TRUCKS plus other parts).

Because the narrow gauge South Pacific Coast railroad grade is across the creek from our property, I started with castings to build a Carter Brothers style truck. Carter Brothers trucks date from the late 1870's and have wooden transoms (cross members), bolsters and spring planks. They were made as swing-motion trucks, where the bolster beam and spring assembly were suspended from hangers to move with the car body independently from the rest of the truck. This was meant to provide a better riding truck and was widely used up through the 1880's.

The SPC group built a pair of these trucks some years ago and here is a link to detailed pictures of the assembly: SPC Truck

Here are parts to build a very common arch bar truck. It is simpler than the Carter Bros. truck but perhaps not quite as strong.

The Thielsen truck actually appears in the 1879 Car Builders Dictionary. When the Carson and Colorado ordered new cars in 1882, they specified Thielsen trucks. What is surprising is that these trucks were made with formed steel channels for transoms in an age when wood was still common as truck structural members. Because the transoms and arch bars were riveted to cast iron ends, they were very strong and durable. After the Southern Pacific bought the C&C and created their own design for trucks, the result was only slightly changed from the original Thielsen design.

Small pedestal, journal box and lid

Small pedestal and solid journal box
Set of 1 small pedestal, 1 journal box (solid), and 1 lid - GP013. This pedestal is 6 1/2" high, 6 1/4" wide, and 2" thick. The journal box is 2" wide and 3 1/8" high. Originally used for 5" scale equipment, it is also suitable for 4" scale or maybe 3" scale.
The journal box is solid with a cored hole that can be used in two ways. One way is to bore and insert a plain or needle bearing in the box. The second method would be to bore the wheel hubs, mount bearings there and have the axle ends pinned inside the bore of the journal box.
A drawing of the box is at drawing GP013




6" Utility Wheels

6 inch wheels

These wheels are from an old pattern for some sort of industrial wheel. They are NOT to any scale but could be used for push cars or other maintenance-of-way cars. From the size of the hub (2 3/4"), they probably were meant for some sort of internal roller bearing.  They are cored to 1 1/8". The tread diameter is 6" - rough. The flanges are 5/16" high and the overall width is  1 3/4". You could also use these to built a miniature mine car.




Something a little bit different


Dirt Train
The Dirt Train

Dump cars were built in gauges from 18 inch to standard gauge and used in many industrial settings. One of my memories of my grandfather was his telling me he ran a "dinky" steam locomotive on a railroad construction project in Montana around 1910. His train may well have been cars like these.



Seattle Car and Foundry
SC&F Dump Car

My inspiration is this page from a Seattle Car and Foundry catalog. It is not clear whether the pedestal jaws are a casting or a fabrication. My design uses a piece of 2" angle with one side milled to 1 3/4" and squares welded into the ends. Notice that the only castings really needed are the journal boxes and lids, the wheels, the couplers, and optionally brake shoes and brake wheel..

Locomotive Parts


Switcher



Switcher bearing housing
Every railroad needs a little gas or diesel switcher. The minimum castings needed include the drivers, the couplers, the brake shoes, and the journal boxes. This journal box is 5 1/2 by 5 inches, sized for a 40 x 80 x 30.2 mm double row ball bearing. It is just a box with a cavity to be machined out and a cover. You can tell your riders the big "W" stands for Whitcomb. The box and cover is GP019



Brake shoes, locomotive
Brake shoes, locomotive, 10" (GP020) or 12" (GP021) diameter.
These are meant to have a slot machined in the back projection to fit a brake lever on a locomotive or speeder. The 12" shoe could be machined for larger diameter wheels with some loss of thickness.
..



Loco poling pocket
GP024 - Poling pocket for car or locomotive. A design like the elliptical poling pockets used on small Porter steam locomotives. Order 2 or 4 for one locomotive.




GP023 - Locomotive link and pin coupler pocket and fancy pin. This is patterned after the coupler pockets used on very small narrow gauge 0-4-0 locomotives, such as Porter or Davenport. This is perhaps small enough to be used on a 3" scale locomotive.



Stack 19 inch
Stack, 19" tall - GP026
This pattern was originally intended for a smoke box diameter of 10 1/2". I built up the pattern to fit a diameter of 12 3/4". The casting can be  machined or ground to fit  diameters throughout this range.

Switch Stand

Harp switch stand 1
Harp switch stand - GP025
Harp switch stand 2
15 1/2 " tall
  This switch stand is patterned after a Union Pacific version used during the construction of the transcontinental railroad in 1868. The one from which I took dimensions ended up on the Sumpter Valley Railroad. I have seen pictures of a similar stand used on the Denver, South Park & Pacific.



7.X" gauge, Rangeley Lakes Truck



Langely Lakes Truck
If you can't quite commit to 15" gauge but want something large scale, you can build in 3 3/4" scale. These are models of 2-foot gauge equipment, the most famous of which in the United States were the Maine 2-footers. Here are the castings needed to build one truck. The drawing shows the configuration first delivered in 1878 - long wheelbase with a single bolster spring on each side.Later versions had a shorter wheelbase and two (or more) springs on each side.

GP030 includes 4 wheels, 4 journal boxes, 4 lids, 4 bolster guides, 4 brake shoes, bolster center plate, and car body center plate. Order two of GP030 to build one CAR.
