• G class trains max ~380 km (236 freedom units), and use shorter cars, run on dedicated high-speed only lines that avoid level crossings, tight turns, etc so they average a significant portion of that (120-150 is common, some lines average almost 200 miles).

      Compare to the fastest trains in America that can do 170, but are limited to 150, and some routes are scheduled as slow as 63 due to tight turns and level crossings, and then average 60.
