  1. thanks for the answers but I wonder if it could be possible to make, by 3d printing, also the switch geometries those guys have done. The last one is a real world switch geometry, is called english switch. many thanks and my best wishes for your activity Sergio
  2. very nice, up to now it has been possible to control the switches only with some modifications, as explained in: just for curiosity, do you think it would be possible the switch geometry illustrated above and also in:

    Hi my compliments to your interpretation of this train. I don't understand the sterile polemic post of fonderiadigitale, there are plenty of replicas around, how many Big-Boys have been presented? perhaps everybody know who has been the first? and why one should mention him? He has not WORKED for it, he has done it for fun. There are no intellectual properties on modeling trains, we are playing! Sergio
  4. The project for the largest Telescope ever becames a wonderful LEGO model: enjoy
  5. wunderschoen! in 22.5 garten bahn! I'm sure you know it but for the others, they can see it in action: as regard the br46 you are right considering your scales, but in L-gauge it should be possible, but not on standard curves. Have you considered the 3d printed wheels recently proposed on this forum too?
  6. mmh intriguing, since it's not the br46 could it be the br45, you love tenderlokomotiven, not the largest but the second one, 6 axes... I cannot wait to see it..
  7. may I suggest a link to Lego Sodor : S.
  8. Hi Sven I'm delighted by your cure of prototypical shape, now your small (relatively) shunter is even more wonderful. Is the BuWizz really so better than LEGO original? I mean, not only for the size. I'm happy to hear your next model will have opening doors, (I'm also found of "gestallt" but details are important too) best wishes for the BIG model (the bulgarian?) Sergio and Eros

    Very nice model, well detailed, as usual in your realizations. The Lego track geometry proves, once more, to be very poor for modeling. Sergio and Eros

    well, from the table the 1,2 mm is the maximum depth of flanges not the standard, LEGO are all 3mm tall, but, as I said, the main problem are the tracks, the 1,2mm H0 still runs on their tracks, 3mm LEGO are not running on "scaled" (1:38) tracks (code 200 Gauge1), as you well know. Not to speak about the switches.. cheers Sergio

    Hello 12V. really nice, again you propose very attractive techniques to model the details which are the spirit of the locomotives. Also the "not exact" rendering of the frontal gains a lot from your solutions, better than the original prototype.. Sergio and Eros
  12. How Do I Train? (adapted from a talk)

    I agree with you about the comically large LEGO flanges, and therefore to consider it as the "real" diameter to take into account for scale modelling. Nevertheless also doing so you are facing with a lack of choices: the largest BBB wheel is 36mm which is (at 1:38) equal to a real 1368mm diameter wheel. Ok you have a lot of lokos to model but not the large beautiful steam engines everybody likes, for instance the "flying scotsman" which inspired the Emerald night (LNER Class A3 4472 with a 2033mm wheel diameter!). The Emerald is nice to play with and the new wheels are a succes, but the scale is simply ridiculous. Probably the real problem are the tracks, I guess a very large wheel simply doesn't work on standard lego tracks, not only for the curve radius but also for the profile of rails (they are not vignoles). Always speaking of "scale modelling", you should consider the "static" solution, which Tenderlok has so well investigated (see the main page of BBB for confirmation).
  13. How Do I Train? (adapted from a talk)

    well, very young babies indeed, they have no knees and a 6 or 7 years old boy don't share proportions with minifigs. Let's say they are studied to "move" us as puppies do.. The discussion has been proposed to investigate the possibilities to model in scale with LEGO, for me the answer is yes but only for selected prototypes, the main problem is actually the lack of choice in diameter wheels.
  14. How Do I Train? (adapted from a talk)

    Ok, first of all let's say that we are playing and everyone is free to do everything, said that, the percentual change in 1:87 (almost correct scale 1435:16=89) and 1:72 (uk wrong! scale) is smaller than your 1:38 to 1:48, so your difference will be more pronounced. When I speak about toys or models I'm referring to the usual LEGO train sets that are really too tight (6 studs) to "model" the reality. Since you have started the topic about exact scaling these are simply my concerns about it, probably your models will be fantastic. Take into account that a large model allows you to define better the small details of the lokos. regards Sergio
  15. How Do I Train? (adapted from a talk)

    well it is what we are facing with . I mean, if the tracks system (including switches) is dimensioned to 38mm this is the right scale, other scales simply don't work, as our friend Tenderlok teaches us, the way to go to is to adopt other tracks system, if you need a 1:48 scale you should look for a 30mm gauge (O-scale has 32mm, acceptable). One thing is to play (like children do) other is to model in scale. Your technique is very interesting but I guess if the final products will be in scale. Sergio
