@williampietri I see, actually, I started work on some UI switches to toggle the labels on and off. I do think it's cool/useful. Those UI elements were causing the page layout to get all weird though. I need do some debugging/testing, but I think it's doable.

@geographile That's a good point. There's usually 2 approaches to make diagrams more color-blind/color-deficient friendly: differentiate things by brightness, or differentiate them by shape, rather than by color. The former would not be that hard to implement. I will add it to my todo list.
Haha, I'm really looking hoping BART reaches Diridon station before too long. That would be so useful.

@williampietri Oh that's an interesting point about the collisions. I'm worried that adding two tracks might make the map more difficult to read. Maybe I can offset the markers a little bit depending on their direction though.
Definitely plan to animate the moving trains eventually, and also add station information.
