  1. Another possible problem with this; wouldn't the cylinders have to be inclined slightly, to get the connecting rods and cranks in the correct positions at top and bottom centres?
  2. Stalybridge Celtic. It's as interesting for us as well, what with us and Hyde United in the Premier Division, and Droylsden and Mossley (and Glossop!) in the West Division. Any suggestion of amalgamating any of the six clubs in Tameside is fiercely resisted.
  3. I would have, as normal. However, our opponents, North Ferriby United, were wound up at the start of the week. Our chairman has put on a social event instead, since home games have been hard to come by at the moment; we haven't had one in March, and only three this year.
  4. In ours, in about 2005, we had a candidate imposed ahead of the one who the CLP chose. Our last AGM had about 90 turn up, excluding the executive committee
  5. I think that, in the Labour Party at least, the days of the executive parachuting the candidate of their choice into "Safe" seats is over. Certainly, the three MPs in the local borough were selected by the local CLPs; I would imagine, at that time (2010-2014), by a vote of the management committee. These days, in most CLPs, it would be a vote of all members who could bother to attend the selection meeting. Candidates from outside the constituency are still able to put themselves forward, but it's unlikely that they would be imposed.
  6. Sent me back to the main menu
  7. Yes! The 16T or whatever, in the left-hand information box, is the maximum loading of the wagon. You add the tare weight, in the right hand information box, to that. How often they were under or overloaded is a moot point. A volume of dry coal weighing 16 tons would weigh more if it rained, for instance.
  8. I've actually had to attempt to overhaul, and in the end replace, ordinary steam valves with severely wire-drawn seats, despite those seats having special finishes (stellited). Yes, superheating didn't really take off until special high-temperature oils had been developed.
  9. So what you're saying is when you give the full unit name, and it has one of the prefixes, it should be written it lower case throughout, but when it's on its own or abbreviated, if it's one of those named for scientist (Joule, Watt, Volt, etc.,) it's capitalised? I well remember, at one of the drawing offices I worked at, the d.o. supervisor sent round a sheet with the "Correct way to write down SI units, e.g. mm for millimetres and not MM, which is, of course, Mega Mega.
  10. The 'dryness' of the seam surely depends on how much of the latent heat has been added, as I recall. I always thought one of the reasons for superheating the steam was to prevent condensation when the steam is fully expanded at exhaust; isn't one of the penalties of steam with water droplets in it that you get erosion of the valve faces?
  11. I meant per kilogram. All my heat engines coursework was in SI units
  12. Remember steam is just a medium for getting energy from one place to another, so that the energy can be converted to work. As I remember from my college days; I#m going to get a rollocking from JJB, I suspect! Hot water at 100degrees C contains roughly 420 kiloJoules of energy. After you've added the energy to get to this point, you've got hot water just beginning to boil; the liquid water is turning into a vapour (steam). As you add more and more heat, a greater proportion of the water is turned to steam. If I recall the amount of heat required to turn a mass of water into an equal mass of dry steam is around 2.2 MegaJoules, at 100 degrees C, and it's this latent heat of vaporisation which makes steam so useful. If you use the steam to move a piston in a cylinder, some of the energy is given up as work; if you cut off the steam inlet at a point before the end of the piston stroke, more energy is lost from the steam as the pressure drops. Obviously, the pressure cannot go below atmospheric, or the steam won't go up the chimney. As the steam expands, it cools, and as it does so some of it will condense back to water, if it's not superheated. It's the very poor expansion ratio (1 to 5 is about the maximum you can get away with, IIRC) that gives the simple steam reciprocating engine/steam locomotive boiler combination its low efficiency. In a petrol engine, you can get away with 12 to 1 (?), and for a diesel it's even higher.
  13. Would have thought that there wasn't the capacity between Deansgate and Piccadilly at that time of day, the way the line is set up at the moment. If Manchester City Council had not objected to the demolition of the Star and Garter, the extra tracks to increase capacity could have been built. Otherwise, a great idea. Run it from Blackpool!
  14. Which raises the question: is the service intended for passengers between Leeds and Southport, or, say, Leeds to Brighouse, or Brighouse to Man. Vic. and so on? It looks like using one particular set, or two coupled together, to fulfil two or three services.
  15. There was a photo in an early Modellers' Backtrack of the Mildenhall branch train at Cambridge, in 1938. The coaches were ex-G.E. six-wheelers converted for conductor-guard operation.
  16. I don't think Northern have ever had stock as luxurious as the 170/185. They were all leased to TPE.
  17. They seem to be used quite extensively on my local line (Hyde Junction - Glossop/Hadfield)
  18. I've seen a picture of a van similar to the first one, with the end vent plated in, in one of Dave Larkins' wagon books which, at the moment, I can't find.
  19. The Millenium Mills were in the background of the last episode of "Silent Witness" last Monday on BBC1
  20. Sorry, part of a song: "Divvent gan doon the Seghill mine; for alang the way they'll stretch a line; to catch the neck, and break the spine, of the dirty blackleg miner" Another great set of photos.
  21. I think the LNER had some gangwayed articulated twins, didn't they; not just the Silver Jubilee sets, either.
  22. More likely that Woodhead would have been converted to 25kV a.c. if it had survived, as happened to the Hadfield 'stub', but a superb idea nonetheless! I'm trying to imagine catching a 323 stopper to Sheffield.
  23. You could probably add, not too far away, Bootles Oriel Road and New Strand, Edge Hill, Seaforth &Litherland, and several others on Merseyrail to that list
