Code 110 wheels are .110" wide and Code 88 are .088" wide. Code 110 wheels are the common (or "Standard") width wheels and Code 88 are what is called "Semi-Scale" and are used when the modeler wants a more prototypical looking wheel width. Actual HO-Scale prototypical wheel width would be around .067" wide and although they will run OK on the average track they will not go through common turnouts and crossings. Code 88 (.088") is just about the minimum width of wheel that will run on most standard or common track if gauged correctly. It really is a matter of appearances because there's very little operational differences between running Code 110 or Code 88 wheels. Code 88 wheels look really good and are most noticeable on open frame cars like hoppers and tank cars. However, they also look great on boxcars, gondolas, and reefers but not quite as noticeable. As mentioned above track code and wheel code have no relationship meaning Code 110 and Code 88 will run on most any code of track. Track code is simply the measured height of the rail, code 100 is .100" tall, code 83 is .083" tall, code 70 is .070" tall, and so on.

Mounts with a #2 or 2-56 screw. The Barber S-2 70-ton Roller Bearing truck is a logical development from the original friction bearing truck first introduced in the 1940's.

The sturdiness of the Barber® S-2 truck is evidenced by the forty plus years it has rode the rails to date. A careful observer will spot these trucks in interchange use today. This truck can be used under almost any pre-1970 built 70-ton rolling stock.

#561 Arch Bar Self Centering Trucks with 33" Ribbed Back Wheels - HO Scale"HGC" Two Piece Fully Equalized Trucks The Self-Centering Action trucks self align themselves parallel with the car for easier placement on track. Mounts with a #2 or 2-56 screw. The Arch Bar Truck is typical of these trucks from around the turn of the century. Despite the age of these trucks, they saw more than seventy years of service in some applications. The arch bar was allowed in interchange service until about 1941. On railroads that were not common carriers such as logging or other industrial lines, this restriction of the trucks did not apply since the trucks did not operate on rails other than the owner's. The Northern Pacific, for example, used truss rod frame maintenance of way cars fitted with arch bar trucks well into the early 1970's. Many logging railroads also used them at least until then. "HGC" or High Gravity Compound, weighs nearly the same as Metal Trucks but with more detail & a 2 piece split bolster design for more efficient truck equalization, reduced axle friction for greater rolling performance.
