  • Unprotected railway crossings can just have a St. Andrew’s Cross (see the following image) or other type of indication (country specific) at the actual railway crossing and no sign indicating a railway crossing prior to the crossing. The signs at the actual railway crossing are not considered for Traffic Sign implementation. However, all railway crossings with and without a Railway Crossing sign prior to the crossing are applied with a Railway Crossing condition.
