    Almost all of them look like Inverness. Certainly #4 and 6 are. #1 is the only one that isn't. Turntable, next to trees? Dingwall?

    The Skye Bogies are surprisingly dainty-looking locos. Presumably intended for the Dingwall-Kyle line, from the name? The louvred chimneys are very distinctive and, I think, unique to Jones' locos. Does anyone know why he designed them that way? I guess it's to help with the exhaust and draughting, but does it reduce back-pressure somewhere, or improve the draught when not working hard, or what?

    After a little Googling, I can answer my own question: according to the Wikipedia page on Jones' HR locos, "... his special louvered chimney. This invention involved the division of the chimney into a central exhaust tube and an outer concentric ring into which air was projected through the louver slits down the front of the chimney casing. The increase in air resistance was induced by deflector plates. By this means, a draught was supplied when the engine was running with its steam cut off, as happened for long stretches on the hilly Highland line."

    Maybe also to 'lift' drifting smoke when coasting. Just a thought. Ray.

    That was my understanding... Something to do with problems caused by the prevailing winds tending to be in a direction that caused smoke to drift back over the cab, and trying to find a solution to that problem.
