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 or suggestions  to actual construction.

A note about my part and drawing numbering scheme. Names like GCxxx denote raw, unmachined castings. The "xxx" goes from "001" to "099". GPxxx denotes machined or fabricated parts. GP001 to GP099 are parts machined from the corresponding GC001 to GC099 castings. I don't normally offer machind castings, but the GPxxx drawings show the machining operations to be performed. GP101 and up denoted fabricated parts. I don't have these listed for sale, but include drawings as a courtesy to builders. GAxxx denotes assemblies and/or assembly drawings. For instance, the  Carter Bros. truck below is assembly GA006. Assembly drawings also include documentation drawings such as rail and wheel standards and anything else that might be useful for the Grand Scale builder.



Car Parts


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

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 castings to build a very common arch bar truck. This shows a wooden spring plank. A stronger version would use a 4 inch channel as the spring plank.

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. The center, which was a casting on the original design, is easily fabricated as a weldment.

Adding pedestal and spring perch castings makes it possible to build a passenger truck. The following table shows castings to build two TRUCKs

The large pedestal was originally intended to use to build disconnected log trucks. This drawing shows a very simple example made mostly of wood

 
If a logging railroad needed a caboose, one could be built from a single disconnect truck.

Small pedestal, journal box and lid

Small pedestal and solid journal box
Set of 1 small pedestal, 1 journal box (solid), and 1 lid - GC013. 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 (low for 5" scale) 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. I designed a pedestal jaw casting that looks appropriate.

Locomotive Castings


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 GC019



Brake shoes, locomotive
Brake shoes, locomotive, 10" (GC020) or 12" (GC021) 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
GC024 - 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.




GC023 - 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 - GC026
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 - GC025
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.
