Investigate the practicability of "delethalising" the level crossing environment progressively be removing obsolete substantial obstructions, and relocating signal stanchions, equipment housings and other essential structures, sited within 500m of track distance from any level crossing, so that they were at least 5 m from the trackside and investigate the practicality of improving the frangibility of warning light/barrier masts so that they minimised the damage inflicted on vehicles which collided with rail vehicles.
