An accessory consisting of a steel plate, shear stud connectors or welded-on rebar which is embedded into the surface of a concrete element so that other elements can be welded or bolted onto it later.

An L-shaped or similarly shaped accessory attached in a corner between elements to hold them together or to carry a secondary element.

A column shoe or a beam shoe (beam hanger) used to support or secure an element.

Assembly connection element between construction elements to allow for thermic differential expansions.

A cable arranger is a flexible accessory or a part of a component placed around cables to arrange and minimize flexing of them at the point where it is placed.

Sealant, gap filler rod, packing material or other used to close a gap.

Construction material used to manage the passage of water around objects.

A device designed to support and insulate a conductive element. Note: definition from IEC 151-15-39.

A lock is a mechanical or electronic fastening device that is released either by a physical object (e.g., key, fingerprint, RFID card, security token etc.), by supplying secret information (e.g., number permutation, password), or by a combination thereof.

A non-metallic pad placed between rail and baseplate or rail and sleeper, bearer or slab. Note: definition from EN 13481-1.

A component which supports and retains the stock rail and a flat surface upon which the foot of the switch rail slides.

A device that prevents wearing of the rails throughout the flange of wheel to reduce noise emissions. It is often located at inner side of the outer rail in a curve or near turnouts (depends on function wearing or noise reduction).

A component that minimizes pump effects of the substructure.

A rail component that prevents rails from tipping and twisting.

A track elastic cushion is a kind of layer set on grooved sides of a concrete base, which is used for mitigating the impact of longitudinal and lateral load on track structures. A track elastic cushion shall only appear in ballastless track structures.
