  1. Of course, if you really did pick a time of day, nothing would be moving: The sun would be fixed in the sky, no wind would blow, animals and people would be motionless and trains would be stationary. When you think of it that way, it's an anachronism to have trains moving through the scene at all... You could save yourself a fortune in rolling stock and electronics!
  2. There are a few period photos of 48xx in Neil Dimmer's collection here: (Mostly BR era though and very few in colour.) 45xx's in another folder.
  3. Here you are: https://www.bbc.co.uk/sounds/brand/b006qpgr
  4. I think it's good to see a bit more depth behind Hornby's usual PR and marketing hype. A step in the right direction, IMHO. It could probably have been shorter, and I'm sure Hornby will learn and adapt as they make more, but length isn't necessarily off-putting because I think podcast consumers are happy to drop in and out and skip over bits as time and interest allows. It's a modern way of consuming media that I must admit I find slightly alien, having been brought up on the strict schedule of the Radio Times and appointment-to-view telly! (Another option for us linear-media consumers would be to just set it playing while we do something else - in the railway room, perhaps.) P.S. There's a trope in podcasts where two presenters casually chit-chat with each other and one of them pretends not to understand the subject. This is done to bring the listeners along with the conversation but it's very annoying because it's usually obvious that they both know exactly what they're talking about, not least because the chat is clearly scripted! Let's hope Hornby don't go down that rabbit-hole!
  5. Podcasts are huge at the moment because they can be accessed anywhere, anytime on your Smartphone - and almost anyone can make them. It's like a fragmented form of the old broadcast model and, for example, every BBC radio programme is effectively a podcast on BBC Sounds. And conversely, the BBC radio stations now pick up and broadcast a lot of podcasts.
  6. According to "GWR Signalling Practice" (my summary): The relevant levers had extra slots at the 1/4 and 3/4 positions of the lever guides. You pull the lever to the 3/4 slot position and interlocking prevents it going any further. You then wind the hurdy-gurdy until the indicator shows the points have moved the full distance (not sure what indicator). Then the lever is released by the interlocking and it can be moved to the normal position. Same in reverse using the other slot. I guess that the slots connect the generator to the point motor electrically and maybe each slot reverses the polarity of the other? I think Kevin Robertson describes exactly this procedure in one of his books - possibly Burghclere Signalman or the Sutton Scotney book. I got the impression that these electric point motors were not 100% reliable, with signalmen worrying about setting routes that required using them and so getting it done as early as possible in case there was a problem. I think sometimes they had to go through the process a few times before the points were provably set correctly.
  7. Call me a cynic but if either a Bullhead single or double slip can be bought legitimately before midsummer's day I'll be amazed. In fact, I wouldn't be surprised if we have to wait until autumn to see them. That would put the release just within a year of the statement made by Steve Haynes in RM that they would be available "in the coming months"...
  8. Hi Mike @The Stationmaster, On page 173 of GWR Signalling Practice (Smith) there is a photo of an electric point motor at Highclere. It's a low-voltage Westinghouse operated from the "Hurdy-gurdy" in the 'box but the caption doesn't say what type it is. Do you happen to know? Is it an M3 as discussed above?
  9. If you only partly insulate you may get condensation problems on the uninsulated surfaces. Condensation can be a problem in two ways: Either running down the interior surfaces. getting in the electrics and ruining the layout or building up in the structure and encouraging rot. The vapour barrier is the key to preventing condensation problems. It prevents warm wet air from touching cold surfaces if it's installed on the warm side of the insulation and well-sealed. You also need to think a bit about "cold bridges" - places where there's a path through heat conducting materials from warm to cold. Some cold bridges might be unavoidable in a shed but at least you can be pre-warned that they are the places where condensation is most likely to form. Fixing layout baseboards to the wall will make the shed much stronger!
  10. I think the general feeling is that the Accurascale Manor is most likely to be the superior model. (Notice the careful way I phrased that!) They are innovating in many areas, paying great attention to detail and responding positively to feedback. We know this because they are communicating with us much more than Dapol do... That is certainly what I'm betting on. (Sorry Dapol. I have many of your models and they are good but the Accurascale Manor looks like it's going to be something special.)
  11. You are living the dream, Andy!
  12. You don't have to use the whole 75*35ft space! And even if you decide to use the space you don't have to aim to fill it at the first attempt. You could do it in stages, which you complete to a level of satisfaction and then move on to the next stage. Just needs a bit of forward planning to leave room for junctions. That way, if your mojo, your money or your health runs out before you fill the room you're still likely to have something that works well enough to play with.
  13. Lamp? Oh yes, I see. Amazing! (Should be a red bodied lamp for your period, of course...) This all inspired me to have a look at my 14xx again because the sound has always been a bit weedy and I realised I can easily improve it by fitting a bigger speaker. Looking at it afresh it's a really beautiful model. Mine has run quite well in the past but today, not so well... Motion full of cat hairs...
  14. YouChoos fitted one of the new MS decoders into a DJM 14xx, crucially with useful stay-alive, for @Andy Keane's Helston. But it's a very fiddly upgrade! https://www.youchoos.co.uk/Index-Resource.php?L1=Guides&Item=OODJM14XX-MS
  15. The technology used here is ultrasonic vapourisation using a piezoelectric transducer. It's a really neat way for making "smoke and steam" for model steam locos because it's solid-state and can be instantly turned on and off electronically. But it's a shame the exhaust hangs around and falls to the ground after the initial puff.
  16. "Fun" or "Pain"? Maybe this is not such a good idea. You really want to know the position of the couplings rather than the locos... And you really want to measure those positions changing, not just have a binary notification that it has reached a certain point...
  17. The advantage of current sensing is that it is completely invisible and won't get interference from ambient sources like bright sunlight. Isn't precise position input using current sensing just a question of more (smaller) isolated sections of track?
  18. Occupancy detection by current sensing:
  19. That's a really nice solution given the constraints that you've got. Maybe the sidings in the goods yard could be longer - you've got the room to do it. If the oval was a few inches shorter there would be more room to model the tunnel mouth on the far right properly. Maybe the station buildings should be at the left end of the platform? (And do you need both a station building and a shelter on the same platform?) If you could squeeze 2 or 3 more inches width you could add a passing loop to the station, which would add to the interest.
  20. Nice single road engine shed. Just right for remote BLTs.
  21. Today, the parents would simply ring their son on his mobile and they might even track his phone's GPS location to know where he was at all times. Some things have progressed since the 1930's...
  22. Careful now! A 14xx is auto-fitted but a 58xx is not... If your 14xx has the auto connection gubbins on the buffer beams and the battery box under the right rear of the running plate then she should really be backdated to a 48xx.
  23. Indeed. And so, for crossing under the track, why would you go to the trouble of using channel rodding (even if the correct rollers existed) with round adaptors at each end and the difficulty of making the round-to-channel connections under the rails and between the sleepers? Much simpler to run a single length of round rodding with appropriate bends formed into it to connect from a crank on one side, down under the track and up again to another crank or whatever connection is needed. That's my thesis.
  24. Round rodding could be forged (bent) to whatever profile is needed for cross rods at individual locations. Channel rodding can't. That may also have been a factor.
  25. I went to the BRM Bristol Model Railway Exhibition today. It was good to be back at a show and not feel that my health was under immediate threat from being in the presence of 1000's of people. Having said that, very few people were wearing masks and I didn't either so it's probably the greatest risk I've encountered of getting the horrible Covid! The car parks were full and the overflow car park (a recently mown field) was also nearly full when I got there. The venue was heaving! My RMweb Goldness got me in for free, as advertised. There were a large number of layouts but only one really caught my eye - a 7mm broad gauge era goods yard/wharf with toad-like fat little dark green saddle tank locos shunting very Victorian-style wagons. No manufacturers, no EPs, but lots of second hand traders, bits-and-pieces stalls and a few society stands. I was looking for a Castle but couldn't find a decent, reasonably modern one. Came away with yet another Star, Knight of the Grand Cross, which looks to be in good nick and it has curly steam pipes! Almost unused with the accessories pack unopened. Also some new books including the handsome (and expensive) new Lightmoor book on the Wellington, Much Wenlock and Craven Arms branch.
