200series

200series, often written with a hyphen as 200-series, is a generic designation used across several industries to label a family of related models, components, or units. It does not point to a single object but to a naming convention where the number 200 functions as a series identifier within a given context. Because the designation is not standardized, its exact meaning varies by domain, manufacturer, and country.

In transportation and rail sectors, 200-series designations have been applied to multiple classes of rolling stock by different operators. Each 200-series model is defined by its own specifications, work environment, and service history, and may range from high-speed trains to commuter EMUs or locomotive subclasses. As a result, a 200-series train in one country is not the same as a 200-series train elsewhere.

In electronics and consumer manufacturing, 200-series labels are sometimes used to group related components or devices within a product line. The 200-series designation may indicate generation or feature tiers in a catalog, and subsequent releases may carry higher series numbers such as 201-series or 202-series.

Other uses of 200-series designations appear in software, automotive parts, and standards documentation, where the number helps categorize families of items without implying a specific shared function across all applications. Because the term is context-dependent, identifying the exact meaning of a 200-series designation requires reference to the relevant domain, manufacturer, and documentation.
