This passing problem was solved a long time ago, it’s just that the freight rail corps in the US have “optimized” for trains that are longer than the passing rail sections. It’s extremely bad for the entire rail industry and the cause of many of the derailments and accidents, but because capital always gets its way in the US, nothing significantly has changed to resolve the issue.
It’s very frustrating how often there are perfectly workable solutions to making the world better, but if it doesn’t have a fat profit margin, it just gets strangled to death by capital interests in this country.




The freight industry is a huge source of the problems in the US rail system. It should not be able to run trains longer than the passing sections, but it does it anyway because “it reduces labor costs”. Running longer trains is terrible from an engineering perspective.
