  1. Yes, it would be good to have confirmation from independent sources. I'm using "Great Western Moguls and Prairies" by David Maidment, 2016. I can't see RCTS mentioned in the Bibliography...?
  2. The crank pin might just have not been tightened properly at the factory and worked loose. This is quite a common failing for new steam locos in my experience. Tightening it back up might be all that's needed - if you can get at it...
  3. Is it fair to keep on characterising Dapol this way because you had a bad experience with a particular configuration of a particular product? I'm not surprised that Dapol were unable to say anything conclusive about Neal's problem because it may have been the first report of these symptoms they heard. It's still early days for this model.
  4. You only need a turntable big enough to turn the locos likely to be used on your branch line. Here’s Launceston: https://maps.nls.uk/view/105992299 (annoyingly in the very bottom left corner of the map). Notice that there are two stations right next to each other. I’m only thinking about the GWR terminus to the North. From the top: Back/mileage siding Goods shed siding End loading dock Platform loop Release loop for both platform and goods loop either side Goods loop / cattle dock / engine shed headshunt Kickback engine s
  5. That's a lovely plan and concept. I see that although your layout is end to end, the station itself is a through-station and the loop really is a passing loop, not a terminus run round loop as I had assumed. So please excuse my incorrectly labelled switches above! P.S. Don't forget the trap points on exit from the goods yards...
  6. Yes, and Yes. You might have section switches on your end-to-end so that you can shunt at one end while locos at the other end don't move without having to set the points against them. Even if the entire layout is one section I think it would still be wise to isolate the loco release spur and feed it through a switch. It's a very simple thing to do and gives you some insurance if your plans change in the future. (Just having a layout that you can run stock on changes things!) The wiring could be more minimal than I showed, as Chimer suggests, and I did think about leavi
  7. The loco release spur at the end of the platform needs to have power for its whole length because at this stage you can't guarantee what operations you might use it for. You might need to drive a loco to the very far end for some reason so give it equal importance and attention as any other bit of track. It is usual to allow the power to be turned off for the loco release spur separately from the platform track and the run round loop so that another loco can pick up the train in the platform while the arriving loco stands in the spur. (This operation may or may not have happened pr
  8. Since the middle driving axle is sprung, I wonder if leaving it unsupported might be part of the problem?
  9. Here are a few photos of my sound installation: I removed the plastic coal load and to improve the sound, I cut a hole in the tank, covered with insect mesh, then glued chunky loco coal in using Copydex. The gluing takes a few iterations to ensure that the mesh is hidden and to build the shape you want. The result is that sound will now come directly from the speaker, through the grille, and between the coal lumps, instead of being bounced around in the plastic tender body and coming out underneath. I used a Zimo 40*20*9 speaker because I though
  10. Hi Roger, I'll send you an email. In the meantime, I suggest you edit your post above to remove the email address so that spammers and fraudsters can't see it.
  11. Hi David, You have to switch the frog one way or another and so the method of switching doesn't really affect the answer to your question. If you do the live point blades modification then you have to switch the frog externally. The rails beyond the frog can either be electrically connected to the frog and take all power from it, or have their own power feed and be insulated from the frog. Aside: If you think you might like to use the point blades to switch the frog now but leave open the option to use an external switch later, then there's a simple met
  12. @Harlequin is confused and doesn’t know what to make of this one! Actually, having thought about it, I largely agree with you, David. It’s the mixture of scenic, part scenic and non-scenic scattered around the room that worries me. And the proportions. But it’s hard to see how to arrange the parts any differently without going multi-level, which brings new problems. I think something different would make better use of the space... but Chris said in the OP we’re not allowed to use that ploy in this exercise!
  13. What do you mean by basic CVs @BMS? The decoder will drive the loco perfectly well with its default settings. Any tweaks after that are personal taste and how @checkrail sets them may not be how you would set them. (Things like acceleration, deceleration, top speed, active braking, etc...) BTW: If checkrail's model was Non-sound DCC fitted by Dapol then the decoder is probably not Zimo. The manual says it will be an "Imperium" in that case. But the only sure way to tell is either look at it or read it's identity in the controller. (Dapol sound-fitted models
  14. Hi @liathach: I suspect the "jumping problem" is local to you rather than a real problem with the Mogul. Remember you said: But in May you said this about a Hornby Drummond 700: And in April you said this about Bachmann Halls: The jump to speed step 1 seems to be a common problem for you. I wonder if you are accidentally setting your decoders to 14 speed steps when changing CV29?
  15. I don't have a DC setup, only DCC, so I can't tell you how it runs on DC I'm afraid. There are no unusual settings in the decoder - only a linear speed table to reduce the top speed (i.e. Speed step 0 = 0 volts, then a linear progression up to speed step 127 = about half max voltage). I think it's more about good motor control, which all good DCC decoders have these days. So if this loco was run on a DC setup with pulse width modulation and feedback I would expect it to run similarly. I'll try to measure the b2bs later.
  16. I hope for your sake that the Bachmann 94xx is absolutely perfect in every way then, otherwise you’ll have to reject that too...
  17. Here's my 6336 starting up and running at speed step 1 for 4 chuffs: Zimo MX659N18 decoder. Speed table set up to reduce top speed by half. Tender middle axle rotates fine. No hesitation, no jumps. (Tender body off while I test out different speakers.)
  18. I know some people are keen on having something scenic in front of the fiddle yard but I'm sceptical. It might be OK if the fiddle yard is just for storage of fixed trains but I think it gets in the way when you need to get at the stock to remake trains by hand. Having space in front of the FY to place stock before and after being swapped in and out is very useful when the FY capacity can't hold all your rolling stock. David's suggested extra loop is good. If you rationalise the three lines to run parallel and put the cattle dock on the outside and it would be similar to Launceston
  19. Might be worth some further systematic debugging before you send it back. (Dapol are highly unlikely to say anything about other motors or gear trains - with RTR you get what you're given.) Do you know if the decoder was at factory defaults when you first tried it? If not there could have been some odd setting in there so maybe try resetting the decoder and seeing if that helps. Can you post a video here so we can see what you're seeing?
  20. wiggy1's Wheeltapper video shows a OO model. Hopefully the sounds from an O gauge model will be significantly better than the sounds from a OO gauge because you should be able to fit a decoder with higher amplifier output and a bigger speaker(s), which should improve the frequency response. So what you really want is videos of such a setup in an O gauge model. And I would be interested to see them too!
  21. Here’s a side view of the real thing. The motion bracket is to the front side of the saddle. So Dapol’s rendition isn’t far out. https://www.warwickshirerailways.com/gwr/gwrls219.htm
  22. Not only does Russell say that, Holcroft the man who drew up the design, says, "Although no thought of it had entered into the decision what had been achieved was a tender engine edition of the '3150' class 2-6-2 tank."
