It’s scheduled to arrive in San Francisco at 8:39. If it arrives there at 8:41 or later, this market resolves YES.

If I’m not on said train, resolves based on reports from those who were.

Caltrain has been more reliable lately, but it was very delayed yesterday and seems to be somewhat delayed this morning.

General policy for my markets: In the rare event of a conflict between my resolution criteria and the agreed-upon common-sense spirit of the market, I may resolve it according to the market's spirit or N/A, probably after discussion.
