Underwater Subway
While subways are still used to this very day, they’re slowly and surely becoming extinct. We’re surprised that people still ride those underground deathtraps, considering there are much safer alternatives. Then again, not every city is equipped with above-ground trains that don’t reek of urine and feces.

Somehow, this subway found a new home at the bottom of the sea! Many old subway cars were dumped in places like New Jersey and Georgia. All you skeptics out there, take a deep breath. All hazardous coatings and other risks have been removed from the metal equipment, making it completely safe for the environment and sea life in the vicinity.
