A retaining wall is a construction designed to hold back soil in a landscape or provide additional support to prevent soil erosion downhill. It is often used to create different levels or backdrops, particularly in small-scale settings like dioramas or model scenes.
This modern wall, composed of concrete poured sections, is frequently seen in civil engineering projects such as tunnels and bridge abutments. Over time, the elements leave their mark as dirt and weathering gradually affect the appearance of the concrete, indicating the passage of time....(and trains). The dirty walls have been colored by some local graffiti artists.
