>>13834680 (Pb) NYC to London in 3.5 hours:

Anon has long been interested in the potential of Maglev trains and is aware that the only inhibiting factor to speed is air friction. Therefore, if a vacuum tube is utilised, the friction issue is eliminated and thus the speed becomes limited to technology.

Even as far back as 2014, Chinese Scientists claimed they had built such a vacuum tube Maglev capable of 1800 miles per hour. As such, even with the outdated 2014 public technology, the journey between London and New York would take less than 2 hours.
