One for Southside nerds: I've spent a pleasant couple of hours marking out the routes of Dixon's colliery waggonways. Red (starting west of Windmillcroft Quay): the waggonway on McArthur's map (1778), with my guesswork as a dashed line. Blue (all other branches): the waggonway system c. 1830, just before the Polloc & Govan Railway. Base map: OS 25-inch (parishes), 1858, showing the fully developed railway system and the Paisley Canal. More updates when/if I figure out what was going on...
