1 Answers
Manned railway crossing road sign: Its shape is an equilateral triangle with the apex pointing upwards; its color is yellow with black borders and black patterns, featuring a fence symbol inside. Unmanned railway crossing sign: It is a triangular sign with a yellow background, black borders, and black patterns, distinguished by a train with a smoking chimney inside. Below are other railway signs: 1. Kilometer markers and half-kilometer markers: Placed at every full kilometer and half-kilometer point along a route from the starting point. The primary function of kilometer markers is to precisely indicate the location of the route. For example, when track inspectors patrol and identify issues, they can record and report the exact position based on the kilometer and half-kilometer markers, facilitating timely repairs by maintenance teams. 2. Curve markers: Positioned at the midpoint of a curve on the route, indicating the center mileage of the curve, radius, and the lengths of the curve and transition curve. Circular curve and transition curve start/end markers: Placed at points where a straight line transitions into a transition curve, a transition curve into a circular curve, a circular curve into a transition curve, and a transition curve back into a straight line.
