These level crossing barriers have not moved for some time now. What is the right course of action?

Your answer is correct. When level crossing barriers remain down for a long time, you must not cross the tracks. Instead, you need to report the malfunction to the police. This is important for your safety because the barrier might be stuck while a train is approaching, or there could be a technical problem. Only once the police or railway personnel allow it, may the crossing be used. Never try to cross by yourself, even with extra caution, as this can be extremely dangerous. Always prioritize safety and follow official procedures for faulty barriers.
