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.
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.

The assembly drawing gives the drawing numbers of the subsequent detailed components, quantities required, construction materials and possibly 3D images that can be used to locate individual items. Although mostly consisting of pictographic representations, abbreviations and symbols are used for brevity and additional textual explanations may ...
Interior of a typical goods brake van. Immediately to the left of the doorway is the stove and stove pipe; to the left of this are a firebucket, ducket (blanked off) and sandbox; in front of the stove is the sanding lever; to the right are the handbrake, vacuum brake handle, vacuum gauge and seat
This diagram shows what a breakover angle is. It was created to be placed on the breakover angle page. β° = Breakover angle; C = Underside of chassis; W = Wheel; G = Ground; M = Midpoint of wheelbase: Date: 15 March 2014: Source: I made this diagram using Inkscape: Author: Rlboyce
This clamping action may be manual, automatic or operated using a foot pedal. The front, gate-like, plate of the machine is hinged and may be lifted, forcing the material extended over a straight edge to bend to follow the plate. The bends can be to any angle up to a practical limit of about 120 degrees, somewhat more in the case of a bar ...
The direction of the subduction system changes since the break-off of slab creates the space, which is the major parameter of this model. [4] The evolution diagram showing how the subduction reversal initiated by a break-off slab at subducting plate: Brown colour is the less dense continental crusts; White colour is the oceanic crust; 1.
