  1. The major 'break point' is the 2008 release of the all newly tooled Jubilee, cat. nos 31-175 onwards. The body represents variations of the initial build of 'short firebox' boilers , while the mechanism is a conventional DCC socket fitted unit. (Prior to this series of releases, Bachmann offered a split chassis mechanism model with a body deriving from Mainline, representing the 'sloping throatplate' boilers.)
  2. What you propose is very easy. Remove and bin motor, job done on the loco. But now see all the interest in correcting this old clunker's many deficiencies! What you do is flog it to someone who wants to spend a lot of money, and buy the small relatives Brio or Lego, which is likely to be far better received.
  3. The magic of a near legendary brand name. The Bachmann is in every way superior, except that it has the wrong maker's name on it for a certain sector of OO RTR purchasers.
  4. The dominant 'engine' sound is of the cylinders that exhaust directly via the chimney, which is the two LP cylinders which were conventionally quartered, so giving the regular four beats per revolution. When Deeley was appointed as Midland CME, he altered the Smith/Johnson compound design and simplified the controls, and rebuilt the original five to conform, and this design was continued under Fowler on the LMS. Thus modified the Compounds always started as two cylinder simples, (no steam to the HP cylinder) with compound working commencing once well underway, by the driver opening the regulator fully. Thereafter compound working was maintained until the regulator was fully shut. An acute observer in the right location might have heard the effect of the changeover from simple to compound working, because if the compounding was successful, then the pressure of the LP exhaust ought to have been reduced. Never read such a description. The HP cylinder was set at 135 degrees to the LP cylinder cranks for optimum mechanical balance, but with no direct exhaust path to atmosphere was effectively silent. Had it been significantly audible then the beats would have been 6 per revolution in a very readily recognised pattern compared to the four beats of a simple, bursts of three beats, pause and repeat: Two cylinder: Chuff quiet Chuff quiet Chuff quiet Chuff quiet Chuff quiet Chuff quiet Chuff quiet Chuff quiet Compound: Chuff Chuff Chuff quietChuff Chuff Chuff quiet Chuff Chuff Chuff quietChuff Chuff Chuff
  5. They were as invisible as a not readily visible thing, on the actual vehicles once painted/dirt coated. Inspect in BR service photos taken in good lighting of mk1s, reproduced at roughly 4mm/ft. No seams to be seen. My opinion, it has been decades of looking at inaccurate models that has produced this strange desire for a feature which cannot be seen on a 4 mm model...
  6. Any track/rail and wheel system is a 'package', and appropriate standards have to be applied. The loss of robustness means more care required, the reduction in rail height may well require older deep flanged wheelsets to be changed. Then the question is 'do I want the benefits of this rail section sufficiently to accommodate it?', and for many - for the reasons you mention - the answer will be 'no'. I should think many of us choose to mix it up: cheaper and more robust code 100 out of sight, pay more for smaller rail section track in the scenic locations for better appearance. Typically follow prototype geometry and look very well. On a previous layout I used these in a goods yard where the accumulated filth was up to the rail web in order to avoid the need for adding chairs. The thin 'copperclad' point timbers were matched by the then available RTR OO code 75 plastic sleepered bullhead track by C&L and SMP. That was a whole order of magnitude less robust the than Peco's bh code 75.
  7. Since no one else has pitched in, welcome! As you are using DCC on the layout, you will know that a decoder is required to enable a 'stay alive' to be fitted. That will also make the lights switchable and give you output level control as well. But because the lights - whether LED or filament - simply need power, a simple storage capacitor arrangement might do the trick if all you require is to eliminate flickering. Never tried this. It will be worth looking at the power pick up on the coaches to make sure these are working optimally too.
  8. Probably! Long time since I last saw the pic. and my knowledge of dance crazes pretty much begins and ends with 'the twist'.
  9. I know there was a 'Bunny Hop' about that time as we have a photo of a scandalous great-aunt performing it. (Imagine, she went to Paris and danced in cabaret. Not what girls raised in Plymouth Brethren families were supposed to do.)
  10. Novel, inspiring and fun for the model designer to work on; come to the dry side, where there be monsters... There's still more where this came from, the P1 and U1 for a start and maybe the Raven pacific will get a look in? (Personally I would prefer the smaller stuff, but it is what sells that counts.) Probably the right assessment. It needs Hornby on the box for the required sales volume; and while waiting for them to get around to it, Bachmann have had ten years sales of their Pepp A2s to anyone wanting to have a go at a Thompson carve up from RTR.
  11. "the LMS was considering enlarging the Duchess design to a 70 foot grate 4-6-4. Would make a nice possibility for Hornby to practice their freelancing skills." (The original post from which this is taken appears to have 'evaporated') A model would doubtless be impressive, but the outline proposal reveals the problems with fitting it into the UK's rail network limitations. 24T axleload, and only 12T of coal for a locomotive likely to consume 60lb of coal a mile. (There's little point in going for such an enlarged grate mechanically stoked beast unless planning to burn plenty of coal for a considerable continuous power output advance over the existing 50 sq ft grate pacific.) Had it been built I suspect the regular 10T of coal in the standard tender would have helped with getting it turned on a 70' turntable, and deployment on the Crewe-Glasgow section so that the mightiness could be employed where most required to 'flatten' Shap and Beattock might have been more practical. Alternatively an overline coaler at Crewe to top up enroute (as employed in the US for the F7 4-6-4s on the Hiawatha) to overcome the coal capacity problem without need for the new enlarged eight axle tender. None of which need for a moment concern a model maker of course. Don't recall ever seeing a scratchbuilt model come to that.
  12. That was one of my first thoughts, but came to the conclusion that it couldn't be on measurement grounds, 8' coupled wheelbase (7' on the etch), 6' connecting rods, (7' on the etch) . This is fun, wonder who will actually land this slippery fish?
  13. Quite so. Living in a prosperous location with full employment, I was the only child in my 'infant' school (current years 1 and 2) who had 'gone abroad' at six years old - twice actually! (This was at a time just before the foreign package tour really took off.) Everyone had been to Spain by the end of primary ed. (year 6)...
  14. Mmmm. Never thought to run one through a scanner and keep it on file for future customer enquiries? My sole Dapol loco is the very neat altogether and most satisfactory NBL DH type 2 (TOPS 21): no documentation supplied at all. Enquiries at time of release indicated that this was 'correct'; no documentation available. Something of a pattern there. I like this product, but no documentation of assembly and parts, not even a download?
  15. If it were for a 4mm Atlantic, then the roughly 7' spacing of the two driven axle locations probably limits the field to the GNR large and small (LNER C1 and C2) and the LBSCR H1 and H2; which actually had 6'10" spacing for a miniscule gap between the flanges when on new tyres in the case of the GNR locos, and I believe the LBSCR were the same, but have never looked at a drawing. However, the connecting rods are about 30% short for these classes, not that this totally dismisses the idea: anybody else had seriously incorrectly dimensioned parts in an early etched kit? Thought so...
  16. With a raft of RTR BR mk1 models already produced with prominent roof ribs, unfortunately there may well be demand for further product that 'matches', rather than manufactured on the basis of 'better conforms to prototype appearance'.
  17. I wondered about that, but this component is very long in proportion to the other dimensions. I have something of an idee fixe now, that this must be something narrow gauge. What with the missing parts, we'll probably only get an answer if the one person on here who built 'whatever' from this kit shows up and recognises it!
  18. Good spot, and there's more arising from that. At the left end there are what look to be lifeguards to be bent down, and I reckon if this is a 4mm scale kit the gauge would be 12mm. Isle of Man 2-4-0T?
  19. How true. According to my other half who is local supreme commander of all green and growing things, you have to talk to them. I duly defer to her psycho-biological knowhow, and water, prune, fetch and carry, slash and burn compost, as directed; and stick to physics for my hobby interests, where stuff does what it should without need of verbal guidance.
  20. If you take the bodies off the DMU's - quite a struggle to avoid damage on the Cravens (class 105) which I have - you can then remove the seating moulding to uncover the PCB. Identify the PCB tracks which carry track power. Solder on thin flexible wire to link these tracks between the vehicles. Thus far I have made mine permanently wired pairs, but a plug and socket could be arranged, or even conductive couplings if desired.
  21. Almost done, but it probably should have a nickname; very characteristic of GNR classes, often popular music/dance themed. 'Knick-knack', 'Tango', 'Ragtimer', 'Jazzer', are already taken, you will need to look at what else was in vogue 1918-1922...
  22. Only ideas. For an outside cylinder 4-4-0 (possibly T) with a 7' coupled wheelbase, thus a small wheeled and small overall loco if for 4mm scale. Designed to take an XO4 or compatible motor so likely designed at least thirty years ago.
  23. It's all good, whatever. Made the sales to new customers, and some will subsequently buy more. Among those quite possibly some who have fallen off their mountain bike once too often, and are thinking 'trade it in for something less risky' .
  24. They could and should have looked good, as in HO scale with correct exterior dimensions. There is no problem with post-steam UK HO, our RTR is only made in OO because of the legacy of what was necessary for RTR steam traction models. Had there been a manufacturer wanting to break in to the UK RTR market with deep enough pockets to push it, I reckon the opening of the fixed link was the last clear opportunity to standardise HO for UK post-steam models. Had that happened, then steam would have necessarily stayed with OO at that time. And on the back of that, by now UK steam models would be increasingly available in HO too, as RTR mechanism production technique has advanced significantly over the past 30 years. A finer wheel profile (already applied on some OO RTR without raising complaints of running problems) with width over wheelfaces of 18mm yields 6.75mm each side for accommodating Walschaerts gear and lateral translation, and the splashers not hideously over scale width. But, 'twas not to be...
  25. Ah, Bachmann's DMU's are different again from their twin bogie diesel traction design! The pick up on the split axle principle is very good, all wheels pick up, but the transfer between bogies and the body PCB is made by rubbing contacts. Soldering on flexible wire links is one solution. Adding track power links between powered and trailer cars makes them 'bombproof', whole unit picking up on all wheels.
