The derailment of a Norfolk Southern Corp. train in a small Ohio town last month is putting renewed attention on the role of sensors that railroads use in a bid to prevent such accidents.
The railroad, in response, announced new safety initiatives, including adding 200 temperature detectors to parts of its tracks where existing sensors are at least 15 miles apart, starting near the derailment site in East Palestine.
Major freight railroads plan to add roughly 1,000 of these detectors across their key routes, according to the Association of American Railroads, an industry trade group.
