The massive heat wave, stretching from Maine to Texas, is slowing commuters down and making their waits miserable


A massive heat wave stretching from Maine to Texas is disrupting transit systems nationwide, forcing trains to run slower due to temperature-related speed restrictions. Public transit delays affect Washington DC metro, Amtrak lines, and subway systems in major cities. Masoud Ghandehari explains that "heat expands many mechanical infrastructure systems supporting trains, especially those above ground" causing overhead wires to sag and electronic systems to fail. Underground subway platforms become especially brutal for waiting commuters.
