Passengers Turn Train AC Vents Into Dustbins, Viral Video Shows

Some people on trains are doing something not so nice.

Instead of putting their trash in a bin, they drop it into the air conditioning vent.

The vent is the little opening that blows cool air into the train car.

A worker said passengers who sleep on the top bunk sometimes take off or break the little cover over the vent.

Then they use that hole to throw away their garbage.

Over time, all that trash piles up inside the tube that carries the air.

When garbage fills the tube, air cannot move through it easily.

That means the air conditioner may not cool the compartment as well.

A video of this went viral, meaning lots of people saw it online.

It is important to use a trash can so the train stays clean and cool.
