I believe the 1403 was wrecked at Southampton St Yard in 1987, there are pictures of it wrecked somewhere on the NERail photo archive.
That leaves to 1301 and 1648 to be explained if 1401 was the South Side incident. I believe 1301 was wrecked at Tower or Great Rd in Lincoln and that control car 1651 was ordered to replace that car. If the story is correct that the 1648 was wrecked on it's what to the MBTA, then the 1652 would be it's replacement.
SOMEONE has to have the answer...
