Gwazi advertises 100mph fly-bys (for those of you proficient in math, that's two trains going 50mph in opposite directions). DB Hurricane goes 60 according to rcdb, and I say that's about accurate, not NEAR 80 as their site suggests. Sometimes, it's just inaccurate, other times it's just ADVERTISING!
