I remembered this coming up before, but since I am quickly closing in on the age qualifications for the curmudgeon classification, I could not remember the outcome of that discussion! After checking through the search feature, it came up in 2007 & 2000, but no destination for the boxcab was found in either of those brief discussions. Somewhere in the recesses of my mind, I seem to recall running across some information about its eventual disposal, but at the moment (to quote my 89-year-old mother who died a couple of weeks ago) "I haven't a clue!"
Sorry!
