Definitions

• prior art barriers erected alongside lines of communication, especially railways comprise panels mounted on H uprights by inserting the edges of the panels between the flanges of the uprights.
• One of the drawbacks of prior art barriers, especially those exposed to intense vibrations, is due to the slackening and gradual movement of the panels relative to the uprights, with risk of the panels falling.
