Cash between the tracks

City Controller Scott Stringer produced a report putting a dollar amount on the cost of New York’s now infuriatingly common subway delays: up to $389 million a year. A week or so later, the Independent Budget Office crunched the numbers its own way and settled on a similar price tag: up to $307 million a year.

That’s the cost of being late for work. Of missing a doctor’s appointment. Of having to pay the sitter for an extra hour. (It doesn’t account for the cost of all the Tylenol you have to take when you finally get home.)

The subways are owned by the city (Bill de Blasio, mayor) and operated by the state (Andrew Cuomo, governor). That makes them a shared responsibility that need shared investment.

Cuomo says he’s good for $400 million, half of the additional emergency-plan money needed to get the tracks back on track. De Blasio is refusing to pony up his $400 million share, wanting the state to pay the whole thing.

Think about it: $400 million, if well spent, could save New Yorkers about $350 million or so per year. We’re no math geniuses, but seems like a pretty good deal.
