Standard practice on all of the class 1 roads and most (or maybe all) of the commuter railroads. It's a direct result of the 2008 Metrolink train wreck that killed 25 people and injured 135. The engineer was texting instead of paying attention to trackside signals. Making matters worse, he was texting a railfan friend and said he was planning to give the friend a cab ride and would allow the friend to run the locomotive. Long story short: that's why railroads now have inward-facing cameras and cell phone detectors. And no more cab rides for railfans.
