The triangular warning sign with the symbol of a barrier indicates the proximity of a level crossing with a barrier, meaning it is equipped with barriers or half-barriers. The approach beacon placed below, with three red bars, indicates the distance we are from the said level crossing.The option referring to a level crossing without a barrier is incorrect, as that situation would be signaled with the symbol of a locomotive. The option mentioning three railway tracks is also incorrect, given that the three red bars on the beacon indicate the approach and distance to the level crossing, and not the number of existing train lines.
