20 Things You Somehow Missed In Back To The Future Part 3
2. The Flux Capacitor Is Visible In The Train
When Doc's time travel locomotive takes off, keen an eye on the upper-front portion and you may notice something a little familiar looking.
Yep, that's the flux capacitor - the technological doodad that makes time travel possible - installed where you'd expect the train's light to be.
It's an interesting design change given that the capacitor was housed inside the DeLorean, yet given how considerably more hardy and durable the locomotive probably is, the capacitor evidently doesn't require the same level of protection.
It might seem like a total given in retrospect, but have you really ever noticed this before?
