Congratulations to the Maryland Transit Administration for adopting the practice of posting a daily summary of the performance of the MARC system on its website.

Since early September, the MTA has been posting a regular summary of the previous day’s MARC delays, allong with a scorecard tracking its on-time performannce on a month-to-date and year-to-date basis.

The totals for September as of Thursday show an admirable Penn Line performance for the month of 95 percent – much better than the year-to-date figure of 89 percent. The news from the Camden and Brunswick lines isn’t so rosy – with both scoring in the mid-80s for September.

Riders can find the data here  . Or go to the MTA website  and click on MARC TRAIN at the top. From the menu that pops up, choose MARC Train – Daily Service Digest.

This is the type of transparency that is long overdue at the MTA, which should consider providing this data for  more of its modes. (Local bus could be difficult, but the light rail and Metro should be doable.) Riders are invivited to monitor it for accuracy.
