I vote for M61s on automatic turrets with movement detection, on every carriage, alternating left-right. Pedestrians shot at railroad crossings is but a small, yet acceptable, price to pay for the safe transport of packages. As the system will be expensive, it will have to be state-subsidized, of course. At the end of the day, the parcels services are providing an essential service of first necessity, and it would only make sense that everything is done at a national level to ensure they are functioning correctly. And why stop there? We could also ask defense contractors to design specialized trains. On top of absolute safety, it will have the added benefit of creating good job opportunities!
