@Gloster: you've essentially got it -- and you've been the only responder to the question. The happening concerned, on the T & D; was on May 22nd 1893 (exactly 132 years ago, as of my setting the question yesterday !) -- a Dingle -- Tralee special, mixed goods and passenger stock carrying "pigs and pig buyers" to Tralee for commercial doings there, ran away and became derailed near Glenagalt: three people were killed, as were almost all of the large number of pigs being conveyed. A very few pigs (few enough to be counted on the fingers of one hand) survived unharmed. The prompt (if a little delayed) taking-off of these, for slaughter as planned, caused quite widespread bad feelings in the locality -- many people felt that with these animals' miraculous survival, they ought anyway to have been granted a longer lease of life: a kind of kinship here, with the "Tamworth Two" -- escaping from outside abattoir, and what happened thereafter -- business of 1998. (I find -- with respect -- such sentiments on the part of the rural poor in Ireland some century-and-a-quarter ago, a bit surprising; but "you never know, with people".)
@Gloster -- please set the next question.
