Definition
Equipment refers to the physical articles, instruments, tools, fixtures, and apparatus necessary for carrying on a particular activity, operation, or enterprise. In legal contexts, the term most commonly appears in three distinct settings:
1. General property law and commercial contexts: The tangible, visible personal property used in the operation of a business — furniture, machinery, fixtures, tools, and apparatus present on premises and adapted to the work conducted there.
2. Railroad and transportation law: The rolling stock and mechanical adjuncts necessary to operate a railroad or similar carrier, including locomotives, freight cars, passenger cars, and related apparatus. Equipment in this sense is distinguished from the roadbed and permanent way, which constitute the infrastructure rather than the movable instrumentalities.
3. Maritime and expedition contexts: The collective outfit of supplies, gear, and apparatus assembled for a voyage or expedition — the state of being fully furnished and prepared for a specific undertaking.

Common Language
Modern common usage (Wiktionary): "Any items used in equipping something or someone, for example things needed for an expedition or voyage."
Historical common usage (Webster's 1913): "Whatever is used in equipping; necessaries for an expedition or voyage; the collective designation for the articles comprising an outfit; equipage."
The common meaning and legal meaning are closely aligned in their core sense — physical articles used to accomplish a purpose. The legal distinction lies in precision of application: courts and statutes deploy "equipment" as a defined category of property with consequences for tax treatment, secured financing, valuation, and insurance coverage. Whether a given item qualifies as equipment (rather than inventory, fixtures, or real property) determines which legal rules apply to it, making the categorization a question of law, not merely description.

Common Confusion
Equipment vs. Fixtures: The boundary between equipment (personal property) and fixtures (personal property that has become real property by annexation) is a persistent source of confusion in real estate, secured transactions, and tax law. Equipment typically remains removable and retains its character as personal property; fixtures do not. The same physical object — a commercial refrigeration unit, a manufacturing press — may be equipment in one legal context and a fixture in another, depending on the degree of annexation, the parties' intent, and the applicable legal test.
Equipment vs. Inventory: In commercial and secured transactions law, equipment and inventory are distinct categories of personal property. Inventory is held for sale or lease in the ordinary course of business; equipment is held for use in operations. A fleet of vehicles owned by a rental company may be inventory; the same vehicles owned by a delivery company are equipment. The distinction matters for the scope of security interests and the priority rules governing them.

Why It Matters in Research
The term "equipment" gains legal weight primarily through its role as a defined category in statute and contract. Researchers should be alert to several recurring issues:
Context-dependent meaning: No single universal legal definition governs. Tax codes, secured transactions statutes, insurance policies, lease agreements, and railroad regulations each develop their own working definitions of equipment, often with material differences. A researcher pulling cases from one context and applying them in another risks importing a definition that does not fit.
Railroad equipment trusts: Nineteenth- and early twentieth-century American commercial law generated an enormous body of doctrine around railroad equipment financing — equipment trust certificates, conditional sale agreements, and the rights of equipment lenders versus general creditors in railroad insolvencies. Bouvier's emphasis on railroad equipment reflects the central importance of this body of law in the era when the dictionary was compiled. Researchers working in railroad history or the origins of secured transactions doctrine will find early equipment cases essential.
UCC Article 9 classification: Modern secured transactions law under the Uniform Commercial Code explicitly classifies "equipment" as a category of goods — those bought or used primarily in business but not fitting the definitions of farm products, inventory, or consumer goods. This classification determines perfection rules, default priorities, and remedies. Researchers working backward from UCC-era disputes into pre-Code common law should note that the Code's category structure was an innovation; earlier courts used looser, more contextual definitions.
Valuation and insurance disputes: Whether an asset is "equipment" under a policy or contract directly affects coverage amounts, depreciation treatment, and replacement cost calculations. Historical cases on equipment definition in insurance contexts may use language that predates modern UCC categories and should be read in that light.

Historical Dictionary Support
Bouvier's captures three distinct legal uses — the expedition/voyage sense, the business premises sense, and the railroad sense — that reflect the economic preoccupations of late nineteenth-century American law. The citation to Maryland and California cases alongside a railroad-specific definition (with citation to the Northeastern Reporter) shows courts were already developing context-specific meanings from common stock.
Webster's 1913 and the common legal usage of the period are unusually congruent, which explains why early courts rarely needed to define the term at length — its meaning seemed self-evident from ordinary usage. The legal complexity came not from ambiguity in the word itself but from boundary disputes with adjacent categories (fixtures, inventory, rolling stock as real property).
Bouvier's does not address the modern secured transactions context, which is unsurprising given that Article 9 of the UCC was not enacted until the mid-twentieth century. Researchers should not rely on Bouvier's definitions when working in UCC-governed contexts.

Jurisdictional Note
State courts diverged historically on whether railroad rolling stock constituted personal property (equipment) or a component of the real property of the railroad. This distinction affected mortgage priority, tax assessment, and creditor rights. The UCC's uniform classification of equipment as personal property has largely resolved this in commercial financing contexts, but state property tax statutes may retain independent definitions.
