A lot of you have been asking us when the Red Line will start running its normal number of trains and at regular speeds during rush hour, and today Metro offered an answer of sorts: it’s going to be another 10 days, at a minimum. WMATA says Red Line riders should expect the same packed trains through July 19, thanks to ongoing reduced rush hour service during the NTSB investigation of the June 22 crash. Between now and July 19, Red Line trains will continue to move one at a time at a reduced speed between Takoma and Fort Totten, which is the source of most of the current Red Line troubles — fewer trains can move along the line due to the change, and trains can more easily become backed up. The Takoma station will also continue to close at 10 p.m. for at least the next 10 nights as investigators continue their work. There’s no guarantee in this Metro announcement that July 19 will be the last of it, either. Merely, word is that July 19 is the best case scenario.
