If you are building new freight rail in your country, you can avoid problems (1) and (2) from that comment. Freight rail doesn't take more land than other rail (if anything, it has lower requirements, because lower speeds mean tighter curves are possible). And freight rail doesn't have to be noisier than passenger rail.

However, if you can build any rail at all, you can build freight rail, too.
It's mostly in the US that freight rail is noisier than passenger rail. As explained in https://news.ycombinator.com/item?id=39023890
