Got multiple emails from people saying “Hey, have you seen this yet?” I knew this has been going on but no, I hadn’t seen these particular videos yet. The videos, taken by cjd1701, show rail grinding being done on Interstate. A specialized machine called a rail grinder goes over sections of the alignment after revenue service hours and evens out irregularities in the rails caused by normal wear and tear. For MAX passengers, this translates to a smoother ride.
