Produktbeschreibung

High Quality Content by WIKIPEDIA articles! The term level crossing (also called a railroad crossing, road through railroad, train crossing or grade crossing) is a crossing on one level ("at-grade intersection") without recourse to a bridge or tunnel of a railway line by a road or path. It also applies when a light rail line with separate right-of-way (or a reserved track tramway) crosses a road. Early level crossings had a flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Manual or electrical closable gates that barricaded the roadway were later introduced. The gates were intended to be a complete barrier against intrusion of any road traffic onto the railway. In the early days of the railways much road traffic was horsedrawn or included livestock. It was thus necessary to provide a real barrier. Thus, crossing gates, when closed to road traffic, crossed the entire width of the road. When opened to allow road users to cross the line, the gates were swung across the width of the railway, preventing any pedestrians or animals getting onto the line.
