I don't know why you're being downvoted. I'd say you're wrong, because it's 10/10 times these things don't work. I've seen many similar projects get proposed, funded and abandoned (even some that really did sound more efficient than this to me). The truth is, standard trains are still the cheapest thing you can put on those rails. They're simple, repairable, predictable, they don't break easily, can be easily driven by anyone or automated with standard systems that have been around for decades. Even if a small govt can't buy a new train, they can get second hand trains from other cities, which will still work perfectly for decades.

have you actually looked at what we're talking about, like at all? or are you just following the programming of "small vehicle=bad"?
