So on Google Earth Pro (desktop app) there's a Rail feature to check off under "Transportation." Someone had partially mapped out the old train lines in black overlay. It would be interesting to attempt to explore the lines according to the map, perhaps document it. The British had built this thing all through the forests and swamps in the 19th century. Marvelous engineering! There is going to be a lot of buried tracks all over the place. And there's bound to be plenty lost and abandoned lines even while the British were still here. Too bad these UWI historians that coming out every year seem to have no interest in documenting so much amazing history that has been lost and forgotten forever. Our Wikipedia entries are so lacking, no pride in our unknown history.
