Your timelost subway car reminds me of Tom Lehrer's unrecorded song about the T, from way back, but remembered in folklore. It's to the tune of "Mother."

H is for my alma mater, Harvard,
C is Central, next stop on the line,
K is for the cosy Kendall Station,
C is Charles, across the foamy brine,

P is Park Street, Boston's busy center,
W is Washington, you see,

Put them all together, they spell HCKC PW, [sung with great emphasis]
And that's just what dear old Boston means to me.
