US rail network doesn't need 4-track mains. We run gigantic freights (3+km) on huge loading gauges, so we have many fewer trains. There's also nearly no passenger traffic because it takes 2 full days to go from Chicago to Seattle.
Adding 3 more tracks would be a gigantic capital investment in never-used capacity.
