Buffer-stops seemingly, being hit here; time -- it is felt -- to knock the thing on the head. The answer is Muncaster Mill -- first halt out of Ravenglass, on the Ravenglass & Eskdale. Original clue: "we hear" -- especially from a not-highly-cultured speaker -- "monk 'as ter mill" (engage in industrial-production doings) -- or, in slang from 200-odd years ago, do ("mill" -- noun or verb) fistfighting stuff -- especially re the sport of boxing. Alternative clue -- Muncaster Mill is an anagram of "small runt -- mice".
