  1. A 4.000 cubic metre capacity LPG Tanker
  2. Amateurs - I filled my present transport up a couple of weeks ago - 325,000 litres of diesel...
  3. A pedant would point out that a cubic metre of fresh water weighs a metric tonne - a cubic metre of salt water weighs more... ...fortunately I'm not a pedant...
  4. I wouldn't normally criticize a driver, but that was utterly appalling. Surely the cab speedometer would have given him a clue that the wheels were slipping, as well as the noise/vibration that must have been heard/felt in the cab? I would imagine that the PW team wouldn't be happy either; that sort of thing would gouge lovely pits in the railhead...
  5. Here's one I successfully built a Kirtley 0-4-4T some 20 years ago, & many exhibitions later it's still going strong. What let it down was my 'orrible paint job. One day I'll repaint her. I was pleasantly surprised by how well it actually went together, having heard the horror stories. I also built a MR Steam Railmotor & trailer at the same time. Well, the bodies were nice, & do capture the character of the machine. The power bogie, though, was not so good, & as a consequence it's stopped the job as I just couldn't get it to work, primarily because the valve gear etches were too fine to stand up to running. However, I now have one of John Redrup's excellent kits for the power bogie, so it'll be completed in due course. I must have been lucky, I guess... Worst kits, to me, were Q kits. I did build a Co-Bo, but the castings had more holes in them than a pair of lace knickers - an awful lot of time was spent filling & shaping. As for the supplied motors - I got it going as per design...for about 30 seconds! A new motor bogie arrangement is, again, on the 'to do' list...
  6. I'm presuming that that pipe is the steam exhaust - but it's all a bit of a "rats' nest" of pipework, isn't it! Definitely necessary though, with the pump being so obvious. That's a superb photo for showing off the detailing, by the way. You mentioned the leading axle being compensated, Mike. How's it been done, please? If I recall from upthread, the driving wheels are controlled by beams, so that's clear. Mark
  7. Yes, the current draw on 1500V is much higher than that on 25kV - Power = Volts x Amps, in simple terms.

    EBay madness

    No, but you get a chance to win a visit to the jam butty mines...
  9. Anyone got some spare brain bleach, please?
  10. I remember the 4 which made it to TOPS renumbering - always seemed to be parked up between Sandhills and Liverpool Exchange. Last time home I found my (unbuilt) Craftsman 02 kit, bought some 20 years ago with a view to letting one of my children 'have a go'. Sadly he discovered other interests (football, beer and girls, not necessarily in that order!) before we got round to building it, so it went into the roundtuit cupboard. One day, perhaps... Mark

    EBay madness

    I would say GBP100 would be a bargain, tbh - and that would be buyer is, frankly, out of order. As The Johnster says, he's NOT <entitled> to get a bargain.
  12. In fairness, neither does LNG - you need either a tiny injector (which, interestingly, is fed via a Common Rail HP MGO line and solenoids, a concept last really seen on marine engines when Doxfords still sailed the seas, although the control valves were mechanical) to start the ignition process like a conventional diesel, or a spark plug.
  13. Fair enough re the crankpins, Dave. 2 very valid points I might well take you up on the etch at some point too. Enjoy the rest of the build - hopefully with no major snags. Cheers Mark
  14. This is looking very good - they are nice little locomotives. I have a K's version, built by myself in 1976 "as K's intended", & still going strong, many Exhibitions later. This lovely etched model promises to be much better. I have to admire your using Romford crankpins though - are these 'traditional' ones requiring soldering, or the more recent 'de luxe' version? I wrecked a Gibson wheel once whilst soldering, even though I was as quick as possible with the iron; haven't tried it since, preferring to use Gibson crankpins. Yes, I'm a coward Mark
  15. Using 14mm discs, they're probably pretty much correct across the flanges anyway in OO/EM. That's my excuse, and I'm sticking to it!
  16. Even if the disc was slightly off balance, given the masses involved and the diameter of the mandrel, even a sudden acceleration shouldn't cause the damage you've experienced, Vivian. I've been using discs & my own Dremel for years with no issues. Yes, safety glasses/visor should always be worn anyway when cutting/drilling/grinding with these tools. I'd start off gently with a mandrel on its own & check that it's running true. Once happy, try fast acceleration. If all OK, then try a disc. Again, start slowly. Fingers crossed. Mark
  17. Even an unbalanced cutting disc shouldn't bend the mandrel like that, What happens if you put a new mandrel, without a disc, into the chuck and run it up? Is the mandrel running true? There's something seriously wrong here - as Mick suggests, the mandrels might well be poor quality, but even so, this is unusual. Something bent like that, running at speed, can do some serious damage
  18. Apropos of nothing, I'm intrigued about the "LMS" on that totem, because no LMS route came anywhere near Durham. Through coaches, yes, but not a line. Having said that, the detail escapes me, but ISTR that there was a way into the area that the LNWR were investigating, but the NER (or perhaps the S & D) invested a lot of money in scuppering the idea, by, IIRC, getting there first...
  19. ISTR that it was reported that he had tried to modify the moulds to fit the (obsolete) machine that he had, and that action has now rendered them unusable?
  20. Very true - the flexing will have been made worse because of the hull frames being as small as possible too, I fancy, in order to keep weight down. The South Atlantic seas tend to be bigger than general North Atlantic ones, so more loads were on the hulls. They looked peculiar with the "fix", a very large doubler plate, fastened to the outside of the hulls.
  21. I walked across the bridge at the end of September last year. The Orange Army were already in full swing replacing timbers; it's a huge job to restore this iconic structure, but it is definitely right to do so.
  22. Just looked at the Greenwood web site, out of curiosity. Scary prices for the motors
  23. That Garratt boiler had 6 cylinders to feed, of course, and the boiler wasn't <that> big. Big Bertha (aka Big Emma or simply The Banker) was, if memory serves, hindered more by poor steam passages and valve events at speeds above her normal banking duties.
  24. In fairness, wasn't it a broken axle that caused the W1 to come to grief? Can't put that one down to <ahem> "spirited running"... IIRC it was a Thompson A2/1, was it 60508? that Hoole was involved with - a bogie derailment. Same result though - loco on its side.
  25. One might think so - but if the crew were on 'job and finish', and absent any traffic from Scalby or Gallows Close, why do the extra mileage? Oh for a time machine...
