They finished building an LRT in Ottawa. They've been running totally empty trains on it for months. Clearly they must have built it for the illusion that they had rail transit. (This is called reductio ad absurdum. The cause of the ghost cities, and these empty trains, are both more complex and more interesting from it. In the case of Ottawa, they were having issues getting the trains running properly on it, whether due to issues with the rails or the electrical lines or the railcars. It should be running publicly in a few weeks)
