(sander) U-trap housing Explanation: My choice here; it's effectively the same principle as the U-trap in drains which prevents water flowing away and allowing the foul air to escape, though in this case it is ONLY to prevent sand continuously trickling down the pipes. Hence the idea of a "Treppe", or a step, which the sand has to negotiate, with the help of compressed air or steam, before it is applied to the rails. -------------------------------------------------- Note added at 1 hr (2008-07-11 08:10:47 GMT) -------------------------------------------------- I think in a list such as yours I'd add the sander just as I have shown. True, there won't be too many other U-traps on a steam locomotive - or an electric loco for that matter, but even so... -------------------------------------------------- Note added at 5 hrs (2008-07-11 11:51:05 GMT) -------------------------------------------------- No; the principle is that steam or compressed air lifts sand over the "Treppe", or step - it's clearly shown in one of your diagrams - which as stated is there to stop the sand trickling away down the pipe continuously. I've no idea what the U-pipe in the condensing gear does; the last of the N2's had disappeared from Kings Cross about six years before I started work there. |
