Troubleshooting Guide

If API Status is FAIL:

Check if the MTA API is experiencing downtime
Verify network connectivity from your server
The app will automatically fall back to static schedules

If API succeeds but no trains found:

Check "Trips with Our Stops" - if 0, the feed may not include your stations
Look at "Skip Reasons" to understand why trains are being filtered out
"no_destination_stop" = trains don't go all the way to destination
"past_departure" = trains have already departed

If data source shows Static:

Real-time data returned no matching trains
This is normal late at night when few trains are running
The app falls back to the embedded schedule (Harlem Line only)

Understanding Route IDs:

Route ID "1" = Hudson Line
Route ID "2" = Harlem Line
Route ID "3" = New Haven Line
