        "whatItIs": "A place on a railway line where passenger trains stop to let people board and alight, usually with platforms but fewer facilities and often no points or signals, as distinguished in German practice between a Haltepunkt, a stop without switches, and a Bahnhof, a station with switches, and in Czech practice where dopravna D3 names a traffic point on simplified-operation lines; the registry aliases also include former railway stops, railway points in Canada used as timetable locations, and Estacion de Orizaba, a specific station in Mexico that is an instance. Request stops require passengers to signal the driver, and level crossings and platforms need care.",
        "purpose": "Let an agent explain railway stops, relay definitions across national practice, facilities and operations from railway operators and regulators, describe the named terms and flag the instance, relay platform safety, and distinguish railway stops from full stations, junctions, freight yards and bus or tram stops.",
