Public Transit Icon Set

This has been an on and off project i wanted to do for a while now, and it really all stems from some of the inconsistency in my local public transportation where I live. This is an icon style I've grown a bit fond of over the past few months, So I'm just bringing it over to something more public facing.

Feedback is always appreciated, especially if its about accessibility/readability of the set. If its not immediately obvious what a particular icon is, then I'm probably doing something wrong.

The Icons are still undergoing some pretty lengthy moderation over at the nounproject, but they should be available at some point at the URL below.

//EDIT:
After HALF A YEAR of waiting for approval from the Noun team, the icons were rejected, with minimal reason as to why. Suffice it to say I wont be submitting another batch as it took way too long. I'll provide a public ZIP of this set when i get a chance~

//EDIT2:
Here's that ZIP i mentioned:
