Rush hour in a NY subwaycar, 5 years after it's retirement

It looks so peaceful

looks about as clean as when it was in service

Why the hell is it underwater?

It is under water because they drop the old subway cars in parts of the ocean to help bolster coral reefs and promote ocean ecology in some areas.

No they drop them in the water so fish can have a ride somewhere.

No apostrophe in "its."
