I see that as a fundamentally very different mater.

If I understand, they turned off repeaters ("towers") that they owned and provided, in tunnels and other structures they owned--equipment that they were under no obligation whatever to provide.

A reaction to "bright" marketing ideas that had not been thought-through.

BART's equipment was licensed by the FCC with a main reason being 911 access.

OK--not a Marketing idea, maybe. But still, all the options are in BART's hands--they have emergency phones and people everywhere. The cell service is not a requirement placed upon them, I am pretty sure. -- The unique Characteristics of System Administrators: The fact that they are infallible; and, The fact that they learn from their mistakes.
