On a recent test run, the train sprinted to record-breaking speeds of 281 miles per hour, making it the fastest train in the world.

That’s not even close to the current record, which is 375 mph: https://en.m.wikipedia.org/wiki/Railway_speed_record

Once completed, engineers hope the maglev will reach 621 mph

Yeah, that’s a big “if” right there.

I’m all for high speed rail and I hope they succeed, but this article is terrible.
