That is what we asked for when we were talking about finding alternatives to address the safety upgrades, such as using a whistle. Before starting the meeting today, we wondered how we can manage to track planes in the sky everywhere in the world but not be able to use our telephones to find out when a train is coming.
There are ways to find solutions, with modern technology, or to improve visibility. For example, more plant growth can be removed from a wider area near level crossings. There are all sorts of ways to do things that would improve safety without necessarily using barriers or traffic lights and delivering electricity two miles from the road to the middle of a field.
