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.
Trailer on flatcar, also known as TOFC or piggyback, is the practice of carrying semi-trailers on railroad flatcars. TOFC allows for shippers to move truckloads long distances more cheaply than can be done by having each trailer towed by a truck, since one train can carry more than 100 trailers at once. [ 1 ]
A tie plate, baseplate or sole plate is a steel plate for centering and reinforcing the attachment point on the rail tracks between a flanged T rail and a railroad tie. The tie plate increases bearing area and holds the rail to correct gauge. It is fastened to wooden ties by means of spikes or bolts through holes in the plate.
Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or "points") is a type of electrical switch, found in the ignition systems of spark-ignition internal combustion engines. The switch is automatically operated by a cam driven by the engine.

Piggyback trucking. For semi trucks the trucks can be stacked 4 deep if it is just a day-cab truck and only 3 deep if it has a sleeper-cab.The trucks drive up a ramp or are lifted into place by a tow hook on the front bumper, from a heavy-duty tow truck or overhead crane.
The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not present, on some locomotives – for example, on smaller or articulated types. Conversely, some locomotives have components not listed here.
AS/NZS 3112 compliant plugs have two flat pins forming an inverted V-shape plus a vertical earthing pin. The flat blades measure 6.35 by 1.6 mm (1 ⁄ 4 by 1 ⁄ 16 in) with the active (line) and neutral pins 17.35 mm (11 ⁄ 16 in) long set 30° to the vertical and the vertical earth pin being 20 mm (0.787 in) in length.
