What's the deal with the box full of sand on the MUNI?

I stare at this box every day on my commute and I can't figure out what it's for. There's a vertical window where you can look inside and it appears to have sand inside. What's the point of the box?

Helps traction when the rails are wet. Yes, they dump sand onto the rails.

Yup, that's it. I've seen this happen myself, and it actually works.

Toronto streetcars have a similar box. Apparently it's specifically used to help with braking.

Yup. If you look along the rails on, say, Powell or California during damp weather you'll see sand all over them. Or if you don't you'll hear tires spinning out on them.
