I'm replaying the game lately and passed this section a while ago. Still one of my favourite bits.

My brain tells me "simulation" when I see the elaborate construction and all the little telltale signs that say "no real bridge has these features".

And then the train passed overhead. With the quad speakers and sub rattling away and the whole bridge vibrating, brain gave it up to the glands.

I usually get vertigo in game, but unlike reality it doesn't usually bother me. Except this little bit in game. Oof.
