Two restored PATH train cars give a haunting look into life during the 9/11 attacks

Today is the 15th anniversary of the September 11 attacks, the largest and most destructive terrorist attack that ever took place on US soil.

Remnants of the attack still remain. Today, two museums - the Shoreline Trolley Museum and the Trolley Museum of New York of Kingston, New York - have opened exhibits of two preserved PATH train cars. These were the only two PATH train cars out of seven that have survived the attacks below the World Trade Center as it crumbled.

Though New York City has plenty of other memorials and museums dedicated to the victims of the attack, these trains give a totally immersive look into one of the most haunting moments in US history. Take a look inside.
