We have like 220,000 miles of railroad. We do have nice things: a working freight railroad system that helps reduce transit costs.

Why couldn't this also help with continuous-welded rail?
Your own video points out that it's still prone to trade-offs: rail breaks in the cold are better than buckling in the heat, but what if you could reduce the high point with white paint so you could expand the practical temperature range?
