Show HN: Live MBTA Map (Boston T)

Hi HN! I wanted a way to visualize the MBTA system as a whole, so I hacked this together over the weekend.

It shows the current position of each bus, train, and subway, including a little tail behind each vehicle to show where it's been.

There are plenty of rider-focused experiences built around this data but I'm more interested in the visual aspect of being able to look at the whole thing at once. It's probably not a very practical tool for riders!

Thanks! Hmm, that is odd. I'm currently seeing a few RL trains, but not as many as I'd expect... perhaps I've got a bug in processing the data somewhere.

Edit: Actually, it's probably due to the derailment: https://www.reddit.com/r/boston/comments/px7zii/heads_up_t_i...
