Australia has had a recent spate of hugely expensive government projects where the "thing doesn't fit into the thing it is supposed to fit into", or "is not compatible with the one thing it really should be compatible with." Some random recent examples were: 1. A billion-dollar purchase of train rolling stock that couldn't fit into the tunnels they were supposed to go through, and were too big for the stations it needed to stop at. 2. Another train line where the track curvature was too high, the tunnels were too small, and gradient was too steep for the existing rolling stock to handle. I know nothing about rail engineering except what I learned from playing Railroad Tycoon, but because of that "experience" even I know that those are the three of the four most critical parameters of a rail line! I'm shocked they didn't screw up the gauge and overhead line voltage. 3. Speaking of voltage, the upcoming Sydney South-West Metro is incompatible with the North-West Metro, for like... no reason. 4. The two new Tram lines are also incompatible with each other, despite intersecting and having a very viable use-case for interoperability. 5. The new ferries purchased for the Parramatta river can't safely fit under one of the bridges going over the river. The lack of planning and foresight is just staggering.
