Which is the worst T route to ride when it snows heavily?

We thought we’d ask our Friday Open Thread today rather than tomorrow because of the mess outside. So tell us: Which is the worst T route to ride when it snows heavily?

Might it be any Green Line route, given they’re largely outside? Or is it the Orange Line, which has its own problems in the best of weather? The Red Line can’t be a picnic inbound at rush hour in the snow.

Let us know which route is the biggest hassle once the flakes start falling. You just might help save a fellow commuter from a big headache.
