Steve Martin and the late, great John Candy were in their prime when they made Planes, Trains and Automobiles together, and it was easily one of the best comedies of the late 1980s. Unlike the movie, however, Samsung’s potentially explosive Galaxy Note 7 smartphone is no laughing matter. The FAA banned the Galaxy Note 7 from all flights earlier this month, and international aviation agencies have since followed suit. Now, the Note 7 has also been banned from all Amtrak trains and even from thruway busses at stations where Amtrak operates.

“Samsung Galaxy Note 7 phones are no longer permitted on Amtrak trains, Thruway buses, stations & platforms due to potential safety risks,” the official Pacific Surfliner account tweeted on Thursday afternoon.

The phones present an obvious danger to passengers in enclosed spaces aboard mass transit vehicles, so it makes sense that they would be banned on trains and even in stations. What remains unclear, however, is how Amtrak plans to enforce the ban since train stations do not utilize any agency akin to the TSA, which checks people and scans luggage before allowing passengers to board an airplane.

It seems like only an insane person would continue using Samsung’s Galaxy Note 7 at this point, since the device puts the user and anyone around him or her at risk. We’ve seen people’s cars and even homes destroyed by fires caused by malfunctioning Note 7 handsets. According to a recent report, however, more than 1 million people are still in possession of potentially explosive Note 7 phones.
