wtf?

Existing railways and rolling stock are not the only strange trains of rail travel. In 2015, China unveiled plans to construct a 125-mile tunnel that will link the United States to mainland China via Siberia over the Bering Strait. Assuming that China ever constructs this tunnel, the trip will measure a staggering 8000 miles in length. Travel over several international time zones would extend a typical journey time to approximately 24 hours.
