Japanese railway company starts testing 249mph bullet train speeds:
"This week, Japanese railway company JR East showed off its new Alfa-X, a high-speed
bullet train that is designed to achieve a top speed of 400kph, or 249mph, which would
make it the fastest commercial train in the world. In day-to-day operations, the train
would shuttle passengers at 360kph, or roughly 224mph.
On Friday, JR East will begin testing the Alfa-X, without passengers, on its railways.
According to Bloomberg, the 10-car train will make the trip "between the cities of Aomori
and Sendai at night" for the next three years during a testing phase. JR East hopes to use
the Alfa-X commercially by 2030. Japan News says the line will eventually be extended to
Sapporo."
