AAR - The Association of American Railroads is a railroad trade association that establishes safety and equipment standards for North American freight railroads. 

 

ACC - See cyanoacrylate glue

 

ABS - As opposed to ordinary styrene, acrylonitrile-butadiene-styrene is a harder and more scratch resistant form of plastic.

 

Airbrush - A miniature paint spray gun that is typically used by artists and modelers.  Drawing air from an air compressor, an air tank, a propellant can, or a spare tire, an airbrush's highly controlled paint flow reduces the risk of obscuring fine details.

 

Articulated - Commonly riding on a pair of driver sets, articulated steam locomotives typically feature a pivoting lead driver set (consisting of rods, cylinders, and drivers), which can swing from side to side as it negotiates curves, along with a separate rear driver set, which remains rigidly attached to the engine's boiler.

 

Balsa - Prized by modelers of operational aircraft, this lightweight wood is easily crushed and broken.

 

Basswood - Harder than balsa wood, basswood is a fairly light-weight, tight-grained wood that is often used in model construction.

 

Big Hook - A wrecking crane.

 

Block - An electrically isolated track section that facilitates multiple train operation.

 

Board and Batten Siding - Structural siding that consists of wide, butt jointed, vertical wood planking, with joints that have been covered by wooden strips (battens). 

 

Bolster - Trucks are attached to these cross-members, which are found under each end of a railway car body.  Bolsters are positioned near both ends of a car's underframe.

 

Branch - Tracks that diverge from a mainline in order to reach another railway line, and/or serve a town and/or industry

 

Bumper - Positioned at the end of track sidings, these devices prevent cars and locomotives from running off of the end the track.

 

Butt Joint - Material surfaces that have been joined end to end without any overlapping.

 

Caboose - Found at the end of a freight train and primarily utilized as a crew's quarters, a caboose is sometimes called a bobber, crummy, or way car.

 

Caliper - A precision, calibrated measuring tool that is used to measure thicknesses or distances between surfaces.

 

Can Motor - A motor with a sealed motor casing (i.e., an unexposed motor armature).  Can motors typically draw less amperage, and run cooler and smoother than their open frame counterparts.

 

Cardstock - A generic term for laminated paper sheet material.

 

Casting - Produced from a mold, a copy of an original part that is fabricated out of molten metal, molten plastic, plaster, or polyurethane.

 

Catenary - The overhead wires that provide the power used to propel non-third rail pickup equipped electric locomotives, interurbans, and trolleys.

 

Chemically Blackened - Chemically blackened metal has is bathed in a chemical solution, which produces an off-black or dark brown finish.  For improved realism, railway models that are equipped with metal wheels are often fitted with chemically blackened wheel sets.

 

Circa - About or around (e.g., A manufacturing date and/or a product or subject's era).

 

Clip-On-Truck - An ill conceived 1970's innovation, which made a short appearance in the marketplace due to fragility, Kadee® Micro-Trains® clip-on-trucks were attached to a freight car chassis by integrated plastic mounting ears, rather than conventional truck bolster pins.

 

Coaling Station - A structure where steam locomotives can take on coal.

 

Coaling Tower - A tall structure where coal is hoisted up to elevated storage bins and dumped through chutes into a steam locomotive's tender.

 

Coaling Trestle - An elevated structure where coal is dumped into storage bins from railroad cars or trucks.

Diorama - Typically used for display, modelers often super-detail these small scenes, or cutaways of structures and/or vehicles.

Fiddle Yard - A hidden arrangement of model railway yard tracks that are used to manipulate, stage, and store trains. 

 

Flange - The extended inner edge of a railway wheel, which guides its path along the rails. Incorporating low profile rails (i.e., track of a smaller code) may require the use of smaller wheel flanges.

 

Flash - To be removed from finished parts, flash is excess casting material that has leaked out from the gaps between mold sections.

 

Flywheels - When incorporated in model train locomotives, these circular metal weights improve low speed operation, while allowing a train to coast, rather than abruptly slow down, or stop, when the throttle speed is reduced, or switched off.

 

Frog - Positioned at track intersections, frogs permit railway wheels and flanges to cross or branch off to another track. 

 

Gauge - The distance between the rails as measured from the inside of each railhead.  Formerly the standard center-center spacing for wagon wheels, American "standard gauge" is 4 foot 8-1/2 inches, while "narrow gauge" (defined as anything less than standard gauge) often measures 2 - 3 feet.
