In New York City, the MTA is installing “anti-subway surfing barriers” in between cars on the No. 7 line to prevent the dangerous trend of riding on top of trains, a practice linked to at least 5 deaths and 4 injuries this year. At a cost of $10 million to outfit the full fleet, MTA officials hope this tangible solution, along with their “Ride Inside, Stay Alive” campaign, will keep riders safe. | CBS New York
