China's hyperloop maglev train has achieved the fastest speed ever for a train at 623 km/h, as it prepares to test at up to 1,000 km/h in a 60km long hyperloop test tunnel. (robbreport.com)

Yes, I calculated the acceleration required to accelerate to 387MPH (173m/s) in 1km.
v^2 = 2ax
(173m/s)^2 = 2a(1000m)
a = 14.96m/s^2 = 1.53g
