Well the article includes things like lost productivity due to sitting in traffic, so I think it's fair to point out that there's lost productivity due to train delays. The MTA creates a lot of its own issues though. The bare minimum for a public transit system, in my opinion, should be reliable estimates of how long it will take you to get somewhere, but for non-rush hour trips estimates on the MTA are pretty hit or miss. I've heard this is because the switch operators are all running on some ancient system which is impossible to computerize, but for a system that has tens of billions of dollars in funding I find it hard to buy that they've exhausted every possible option.
