Did anyone hear why 1507 and 1531 were pulled from service? Not long before I saw 1507 beautifully running in service and 1531 was too but I haven’t seen that in a while.
MBTA is storing cars that aren't currently needed for the reduced ridership under COVID, cheaper to store than to maintain. You can bet they'll probably store more in the near future too.
My guess is the 500s/1500s going into storage likely won't run in revenue service again. By the time they're needed the new Rotems will probably be arriving.
