An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
Original Truck Bed Rack Prototype, Invented in 1960 by PIERCE METAL PRODUCTS, Inc. Even though bed racks have gained great popularity over the last decade, the first bed rack was introduced in the 1960s by Pierce Metal Products Inc. [1] Its primary purpose was defined as to build the sides of the carrying box of the truck adjustable to the side of the cargo and to the type of the vehicle.
Other definitions include the surface of the ballast on which the track is laid, [1] the area left after a track has been dismantled and the ballast removed [1] or the track formation beneath the ballast and above the natural ground.

This allows track shoes to break without compromising the ability of the vehicle to move and decrease productivity but increases the overall weight of the track and vehicle. The vehicle's weight is transferred to the bottom length of track by a number of road wheels, or sets of wheels called bogies. While tracked construction equipment ...
Since Kato track is measured in metric units it is easiest to build modules using metric measurements. There are multiple ways to build a T-TRAK module but the most common is the box method. This is basically a lidless, inverted box. For a module of single length (i.e. 310mm of track), the box should be no more than 308mm (12 1/8") wide.
