Background information:
The level crossing gates with the text “Wait until the red light goes out...” are used at the guarded railway crossings. These are railway crossings with light and sound signalling. Logical because the text already refers to the flashing lights. We know the railway fences with the original gray concrete posts, but from the early 2000s, also with the black plastic posts. The blue signage with white text is in fact an addition from the mid-1990s. Before that they only did it with the red and white striped signage. The guarded railway crossings come in many forms. But the traffic intensity of road traffic is usually a lot higher than at the unguarded crossings. There are guarded crossings for pedestrians only, but most can serve regular road traffic as well. When it gets really busy. e.g. with a four-lane road, a grade-separated intersection is being built. The paving shapes at guarded transitions also differ. Some transitions are provided with clinkers or concrete paving stones. But transitions with concrete slabs or asphalt pavement are also common. Where in the 20th century the level crossing gates were the only warning for the crossing track, sometimes single track, but also regularly double track, in the 21st century the level crossing gates are increasingly flanked by fences, such as those in the Markenburg theme "around the track" can be found.
