This morning, we asked a couple of questions about Metro’s record-breaking Saturday — namely: what were Metro’s criteria for estimating the expected crowds, and how high the ridership could have gotten if the trains had been running more frequently. WTOP’s Adam Tuss and TBD’s Dave Jamieson both do us a solid and deliver the answer to the first question — and found that the rally organizers were the ones to blame for us not knowing the answer to the second. Tuss reports that Metro spokesperson Steven Taubenkibel told him that Metro was told to “expect a crowd about the size of the Glenn Beck rally…[a]t the most 100,000 people.” With a crowd at least double that estimates, there were obviously going to be problems. But Taubenkibel also told Tuss that Metro offered rally organizers the option of extra service on Saturday — much like what was provided for the Marine Corps Marathon on Sunday — but the organizers declined. So how much would it have cost organizers for Metro to open the system early and provide a few more trains? Jamieson says that it runs around $29,000.
