This kid just got 10k for saying rail infrastructure is failing due to a lack of maintenance. Specifically the springs at junctions. The main failing here in the US though is that rail maintenance falls to rail companies that have little financial incentive to spend the money on safety. That may be changing, however if the federal government just hands over money with inadequate oversight it will just enrich the companies.
