[Rosie] Thanks for the link. The sounds bring back a few memories. £80,000! The mind boggles. I used to be a keen 'train spotter' as a youngster but the interest waned when girls and cars came along. I had a relative who was a signalman. Occasionally my elder brother and myself would visit him at work in his signal box. Exciting times for a lad. [rab and penelope] Congratulations on your results. Great news.
(Darren) There's only about a quarter of an inch clearance when the piston is right at the end of its stroke and any excess water either knocks the cylinder cover off or bends the connecting rod. Major damage. There are drain cocks which are often opened for the first few puffs when an engine starts out and they blow huge quantities of wet steam ahead of the engine, ruining photos but very necessary. I wasn't there for that recording. I've seen loads of engines slipping on starting but quickly brought under control. It's a rather fearsome sound for a small boy a few feet away on the end of a platform, or for anyone, come to that. (pen) If you're happy so am I. Nothing worse than work worries even they are now behind me.
(Dujon) The wheels only stopped spinning because the valve gear got bent and no longer allowed steam into the cylinders at the right time, rather like a car with a bent camshaft. Interesting that right at the end of the recording the safety valves lift. I'm surprised there was any fire left given the tremendous pull of the exhaust on it. What a mess! I gave up collecting numbers very early but have never lost interest, you could say, but as you imply, there is much else in life.
When is a power cut not a power cut? When they restore the connection at about half the normal voltage. Very dim orangey lights, computer won't start (but monitor OK), TV but no video, kettle wouldn't boil ether let alone water, old Acorn computer OK but not the monitor, strangely. They'd got the full voltage next door but Mrs-next-door-but-one (in her curlers) had the same problem as had an old lady walking her dog. Obviously one of the phases was faulty but I thought you got the full whack or nothing. It seems you may not.
Hello, all. Some of you may remember me from long ago, on other servers. A strange thing happened recently. I discovered that, having moved from Sydney to Edinburgh, and not having played MC for years on account of a Thesis, I happened by complete accident to end up working down the corridor from rab. What do you know? Well, probably that MC is responsible for effects that are not quite normal, for one.
...and when "kt" appeared I had this very odd feeling that we'd met before (although it was only virtually, and - I think - under a different moniker). Anyhoo, welcome back!
[Rosie] The phenomenon is referred to as a 'brown out' - at least here it is. The description is obvious when you think about the affect on your light globes. In the last house I owned I had two phases connected and, on a number of occasions, could have full voltage and current available on some internal circuits and not on others. This of course also applied to total power cuts where only one phase was down. The reason for the variation in equipment functions is simply that some items will run on a range of, say, 180 volts to 260 volts while others need the full pressure (usually 230V +).
(flerdle) It's the first time I've ever seen it, and there were power cuts galore when I was a small child (say late 40's). The voltage here is allowed by statute to vary 10% (up 4 and down 6) but this was down 50%, at a guess. (Dujon) Can't be that, because everyone here is on single phase except industrial premises which have all 3. There were 2 more cuts early this evening. When the first (over an hour) ended it came back on (full voltage) for less than a minute, just enough time to put the candles out before going off again for another 40 minutes or so. Loud, pointed and profane were my exclamations to no-one in particular.
[rab] That's right, I'd forgotten that I changed from kt to Kathryn. That's how long ago it was. Hi, flerdle! Sorry I dropped out of contact for a while there. Are you still in the middle east? Edinburgh's rather nice, actually, with more sun than I had imagined. And hello Simons Mith also. It's amazing how stable the MC community is...
