@rogerfarnworth -- most interesting material -- thanks. That being so: it does strike me that Jamaica is a "Marmite" kind of place -- many people are captivated by it; while many have not a great deal of use for it. I confess to being, mostly, in the latter category: re the country (though I'd be open to the possibility of "conversion", should I ever go there), and its one-time railway. The videos and the pdf are interesting, for sure: but in honesty, the Jamaican railway-as-was, still fails greatly to charm me -- though one would wish it still to be in action, rather than not !
Charles S. Small -- globetrotting American enthusiast who did his thing in sundry far-flung spots some 60 - 70 years ago, and wrote about / illustrated same in his splendid book
Far Wheels (published 1959) -- plainly loved Jamaica and its railway: a chapter of the book is dedicated thereto. He tells of a 1950s journey on the daily Montego Bay -- Kingston mixed train: pleasant description of a ride through lovely tropical scenes, up to Green Vale summit and down the other side, with diverting antics en route from railwaymen and passengers. At the time of Small's journey, the system was still mostly steam-worked; from his pictures, though: to my taste drearily so, in so far as steam traction can ever be dreary -- big, lumbering, ugly 2-8-0s and 4-8-0s, 1940s-built in North America (his mixed was hauled by a USATC 2-8-0 -- brutish-looking thing, "for my money"). Sorry -- I feel dreadfully hard-to-please here; but am being "pitilessly truthful". Post and its contents genuinely highly interesting, notwithstanding ! (Trinidad, at the other end of the Caribbean -- a slightly smaller British-as-was island, also with a quite extensive standard-gauge system -- had, to my mind, a considerably more attractive steam fleet: sadly, Trinidad's railways declined and ultimately ceased to be, a good deal earlier than Jamaica's -- last line there, closed in the late 1960s.)
Can't resist saying -- perhaps a bit naughtily -- love the "caption" faux pas in the illustrations to the pdf: as mentioned, the two captions mistakenly "swapped around" -- and one of them, refers to a "Diesel
Electronic Locomotive" !
