The Central Japan Railway Company is in the midst of an 8-day testing period for its maglev (magnetically levitated) train, which can travel at speeds up to 311mph. Japan's bullet trains currently run at about 200mph.
One hundred passengers got to go for a ride this week during the first trail run in Yamanashi Prefecture.
But… should they really be "testing" this thing out with people on board?
If all goes as planned, the maglev trains will be operational 2027, providing a 40-minute trip between Nagoya and Tokyo (normally 80 minutes).
