MR-63 runs for last time
The MR-63 train is taking its final run Thursday on the blue line. The Journal talks to a few people about the historic rolling stock that dates back to the opening of the metro system.
With some trivia: the trains came with heaters that were never used because, as it turned out, it was ventilators that were needed to keep drivers and passengers comfortable. The original designers can’t have foreseen how much heat would get trapped down there in all seasons.
