If you think back to the start of the year, you might recall the MTA attempting to convince us all in early January that a leading reason for delayed subway trains was dieting women who skipped breakfast. Today’s Daily News has the complete stats on subway delays — the paper catalogues one month’s worth, December 2006 — and it’s a funny thing. The “sick customers” category, which includes those fainting females but also those customers who are legitimately sick, accounted for 392 late trains that month. “Track work/work crews,” meantime, caused 1,640 late trains, “signal trouble” caused 532, and “”guard-light trouble,” whatever that might be, caused 415. Which means that last month’s eat-your-cereal shtick notwithstanding, 2,587 late trains — in those three categories alone — were the MTA’s fault, more than six times as many that were the dieters’ fault. We’re throwing out our muffin right now in protest.
