How about building animal crossings like the ones used on the highway?
It certainly could be done, but it adds to the cost, especially since it is an active ROW that needs to be kept open. Also, for them to be effective, you need to fence off the ROW to redirect the animals to the crossings. Each crossing requires significant design effort to ensure that animals feel safe using them.
From the story, I gather, the idea of animal crossings (underpasses in all liklihood) has been mooted by the proponent, but it appears the initial proposal lacked any material discussion on this; it also appears as though there hasn't been consideration given (yet) to the fact that any crossing would also have to cross the CP tracks, not merely the new track.
Frankly, I find that a bit hard to believe, but that's what the story seems to suggest and I'm inclined to wonder if just a lack of engagement/transparency is at issue here; or whether the project idea is truly half-baked.
The proponent, it seems, is also open to studying using warning/track intrusion systems that would use noise/light to warn animals to get off the track. Its unclear to me whether the effectiveness of this idea has been proven in the real world; and I'd be interested to hear from our industry experts on that.
