TS 12775

TS 12775 is a vocational standard focused on the rail switchman occupation. In railway operations, a switchman is part of the personnel responsible for directing train movements in a safe and orderly way, with work centered on keeping turnouts correctly set, coordinating route changes, and supporting trackside operating discipline. The standard’s main purpose is to define the occupational frame used to describe the role, competence, and assessment basis for this profession.

How the occupational terminology fits together

In vocational standards of this kind, the term ‘occupation’ describes the role and expected professional level of the person, rather than the detailed day-to-day procedures of a workplace. In the railway context, a turnout is the track component that allows a train to move from one route to another; the switchman is the worker associated with ensuring that this infrastructure is used correctly within operating rules. As a result, equipment awareness, attention, communication, and operational discipline all belong to the same professional profile.

What this standard covers

Based on the supplied scope, this standard covers the rail switchman working in the rail switchman occupation, including classification, specifications, qualifications, evaluation and testing criteria, as well as the tools and equipment used in the profession. This means the document does more than name the job: it also frames different levels of the occupation and the logic used to assess competence. The referenced TCDD regulation provides the broader institutional background for movement personnel duties, authority, and training.

In general railway practice, correct handling of turnouts is critical for route integrity and traffic continuity. For that reason, the switchman role is associated not only with physical handling of equipment but also with compliance with operating instructions, situational awareness, and work practices that support safe railway movement. TS 12775 presents this profession within a standardized terminology and assessment framework.
