> Using three tons vehicles for long-distance journeys or for the transport of goods isn’t efficient: trains (and last-mile delivery on cargo bikes) are a lot more economical You are right - Rail freight is extremely expensive (typically more expensive than road except for very long routes) and cargo bikes have a tiny payload. Think about container ships - massive vehicle and much lower cost vs rail freight (dependent on distance).
