Is Caltrain down for everyone or just me?
Right now down.now isn't seeing a broad Caltrain outage, so the problem is most likely local to you — your connection, your device, or the app itself. Try the app on mobile data instead of Wi-Fi, then restart the router. If reports start arriving from other people, this page flips to an outage within minutes.

How do I report a Caltrain problem?
Use the report panel on this page and pick what's not working — it takes one tap and no account. Reports are anonymous, and they feed the live signal on this page immediately.
How does down.now know if Caltrain is down?
Down.Now watches two crowd signals for Caltrain — anonymous reports submitted here, and public social-media posts about it — and compares the live volume against what's normal for that hour of the day. A sustained spike above that baseline opens an incident, which is usually visible before an official confirmation. We measure what users report, not Caltrain's servers directly.
