Good to know

• Production only runs bus and Commuter Rail. Subway events come from LAMP via mbta-performance.
• This is one of the few things on EC2, because it needs a constant connection.

gobble-wrta

gobble-wrta adapts gobble for Worcester's WRTA buses. It polls WRTA's vehicle API and publishes dashboard-style event CSVs plus an unofficial GTFS-Realtime feed. It runs in Docker on a small DigitalOcean server, not AWS, and isn't wired into the dashboard yet.
