I know you're describing pathological examples to make your point, but:
> Would you rather have a train that arrives one minute late every single day, for a 0% on-time record
At this point, the operator should just update the schedule to reflect actual travel speed.

What about a train that idles for an extra 0-15 minutes, in order to make sure that it arrives on time, because there is 15 minutes of headroom baked into the schedule?
The parent poster notes that trains in Atlanta do just that.

The L train?
Just a few examples:
- Would you rather have a train that arrives one minute late every single day, for a 0% on-time record, or a train that arrives on time 3 out of every 5 times and then is 20 minutes late the other two? How many articles on the subway distinguish between the two types of lateness? It matters a lot.
- You might read that Atlanta's MARTA, for example, has a better on-time performance record than the NYC Subway. Well, that's great, but it's also got rush-hour scheduled headways of 10 minutes, scheduled off-peak headways of 20 minutes or more, and no service entirely at many stations after 9PM (no trains run at all after 2AM). So something that's "late" in New York City still comes before the scheduled train in Atlanta (when the trains there come at all). [0]
- The NYC Subway also has 10 times as many stations as MARTA and 17 times as many miles of track. They say the best camera is the one you have on you. Something like that applies here, too. What's the on-time record for a train that doesn't exist?
MARTA is a random comparison, but it's not uncommon for writers of screeds about the subway to offer up comparisons to other systems devoid of any of the kind of context I provide above.
So, you know: 1) comparisons are difficult; 2) especially if you want to capture what it's actually like to use transit in the cities you're comparing. All of which is to support my original contention that this story has been decontextualized by surly commuters and the idea that a tourist couldn't rely on the subway to get to a concert is nonsense.
