Ha ha - that's a serious consideration. Given my budget, it won't be the only static model in the sidings either. Lack of spares or any second hand market is a problem. It pains me to be dissecting new models. I might have another look at 12mm gauge 3mm kits for ideas.

Yes, I did wonder about that too. There are certainly no guarantees are there. Sourcing bogies and running gear would be the biggest obstacle I guess. I have looked at some of the 3mm guidance out there, but nothing looked as obvious as using those class 50 bogies. Buying new locos to disassemble doesn't seem very sustainable long term though. I'm pretty happy with the 55 body now. There's quite a bit of cleaning up to do now, but I'm aiming for a test print before Christmas. I agree, i'd be very surprised if the mainline diagrams weren't derived from these. I think the measurements are very useful on these though.... plus there's all the rolling stock. . Lots of scope there. I was led to these documents from the 313 wikipedia page, and I've picked those diagrams out. I haven't done much browsing as I know I'll get distracted!

I did a bit more work this evening and here are a couple of angles of the new roof. I've injured my neck and shoulder, which is really slowing me down, but I think I've made a bit of progress there. NB I've discovered quite a resource of BR drawings for loco's and coaching stock at the Barrowmore Model Railway Group website. Perhaps, a bit late for this project, but useful for the future. http://www.barrowmoremrg.co.uk/Prototype.html

Yes, they have a real charm to them. My theme for this work is exploring Hornsey and Harringey around 1980 - but I can't resist the 15 from Finsbury Park TDM. Initially, gaps are quite a draw to me... until I realise how little free time I have. 1:120 is an open field with respect to gaps. It feels like a pretty good size for me too, I did look at 2FS, but I was worried about how much detail I could work into the models. I'll probably end up printing a 55 in 2mm just to see... it would be hard not to.

Yes, there's a decent range there. My Peugeot is still in the body shop! At this scale it's taken a few cycles of priming and fine sanding to get out the printing contours. It does have wheels, and an interior too, somewhere....

Thanks Mike, yes Flying Pig also noticed that. I had a go at reshaping it earlier this evening... but I'm going to sleep on it now and check it over with fresh eyes tomorrow.

I have both those things... A cults3d profile. There aren't any rail specific models on it yet... but my 55 will end up there, and a couple of vehicles I'm doing. https://cults3d.com/en/users/Blefuscu/creations I have a sort of instagram too... https://www.instagram.com/blefuscu114/

One of my half finished projects is a printable bedford MK... from which a TK is only a small step. Only a cab so far, but I will come back to this one. I have also recently printed a model of my dad's peugeot 504, but I haven't finished painting and assembly. My daughter has kicked me off the computer but I'll try and get an image up of it soon. I have also seen packs of 70s and 80s cars on cults3d by RICHEMPORIUM. I haven't printed any myself yet, but they look reasonable. They would need rescaling from OO, but he's tagged them as N gauge too so 1:120 should be fine. https://cults3d.com/en/3d-model/game/austin-mini-metro-1980-to-1990 For some reason I only bookmarked the mini metro but you can find the others from there.

Oh dear, you seem to be right! I was using them in front/right/top orthographic views... but I look at it now and my front orthographic is well off. I'm trying to work out what I did there... because the side view is pretty good. The nose is just a bit high where I rounded it, but otherwise fine. In any case, it's me, not the book. Sorry book. I think I can pat it and prod it into shape. Although the temptation to start anew, with all my new found knowledge, is growing stronger. I look forward to seeing the 15 one day. As I'm already thinking of redoing this one I can relate to that!

Yes, that too. Although when it comes to reading the flow of the lines I find it helpful to have a real one to study. One day I would like to take one of my prints up to York or Barrow Hill and offer it up against a real one and really get into some of the problem areas. Joining the Model Railway Club at Kings Cross is something I've considered - they have a big library. Otherwise, efforts to increase my personal library of reference material have been met with A Stern Gaze, so I have been mainly limited to an internet search. Considering the breadth of literature on the Deltic I was surprised by the lack of drawings I found online. I certainly didn't find anything better than the example in British Rail Diesel Locomotives. I relied too heavily on that drawing when drafting the initial form of the body - which is harder to recover from later - so that's a lesson learnt! To be fair to the authors, over the course of this exercise, if I was scratch building this in 1988 and achieved anything close to those drawings I would have been rather pleased with it. The help I have received in this thread has been extremely valuable though. I wouldn't have had that in 1988. It's almost tempting to open a thread for my next subject but I'll probably have a go at it first... and there's this one to finish first. I'm going to carry out some sort of adjustment to the roof, and then i'll probably call it and go for a test print.

I was pondering on this overnight. I wonder if it would be possible to temporarily blank off the window and flood them with resin (UV or crystal epoxy?) without the need to glaze them with plastic at all. In OO it might be too wobbly, like a 16th century window, but for TT or N perhaps we could get away with it. BTW - is your class 15 model available anywhere? There was a Class 15 at Finsbury Park, so it's kind of on my list, at some point in the future.

I feared as much. According to my front elevation in the book, it looked OK. However from the photographs of the roof I understand what you mean about the flatter ellipse. I might see if I can coax that shape out gently without destroying the roof details. I think the end to end taper is ok... at least, it does match the top elevation of the plan i have. In the last images I posted the turnunder does seem to extend too far toward the nose. I have since done a bit of work on that while getting the buffers to look right. Yes, there is a lot more going on here than I appreciated when I started. Given the nature of some of these curves, a trip to York might have been a good idea. Overall, for my first locomotive, I'm quite pleased with how it's coming along - but I'll be happy to try an EMU next!

Yes, I was thinking of just printing them as a guide and cutting them in polycarbonate. Acetate would do as well, I'm sure. I'm not looking forward to fitting them. I really do relate to your position on too many projects. You have some nice models there though. I'm not too worried about my 55 appearing rtr in 1:120 soon, although I'm sure it will in time. I like making things anyway.

Thank you, and thanks for spotting that! I have obviously been looking too closely, and for too long, to spot that. I will offer it up against some of the new images I have from Brian Daniels. The wind screens themselves are actually only blocked in temporarily at the moment. I think they are too deep, bescause at some point I tweaked the length of the model. I'll take that bit of glass out when I prepare for printing at the end though. (I assume it will be best to glaze the windows.... although I could attempt to print them in clear resin. I have never tried that before, my feeling is the flat windscreens are going show too many print artifacts.)

That's good to know. I'm pretty sure I can get my sides down to 1mm on my resin printer. I have just finished a Peugeot 504 in TT120, and that has some very thin section in the body work. I'm not afraid to take on a chassis too, if I need to. I will already need to extend the wheelbase of the bogies if I use the 50 parts.

Thanks so much - those images of Brian's are really fantastic! I really have no excuses now. The model reference looks good too. I didn't want to refer too much to Accurascale's OO model, as they have done such a good job it felt like cheating a bit. I also know there's a lot going on there that I will struggle to reproduce at this scale. From my experience thus far - I really don't think they remastered any of the older classes in my second edition, the ends don't quite line up for example. Subsequently, I too use a lot of photo's too - but I like to have some kind of orthographic projection as a starting point.

I've been working on the roof. I acknowledge that it is, to some extent a work of fiction. I have found less reference material for the top of the deltic, and am a little too far away from one to just go and have a look. However, I'm also conscious that some of these details are going to be very small in 1:120, so I have needed to make some compromises in my interpretation of what I can see. There are obviously a lot of other models of 55's about too - and they have been pretty useful. There's still quite a to do list... until the class 50 is available I have no wheels, however, I'd like to get all the modelling over with now and have a test print in hand. No buffers yet. Holes/vents to be added to the center of the roof, and the vent on the side of the end needs doing. Horns and wipers will probably be etched parts, and I need to make holes in the ends for wires. The end windows will be cut through and require glazing. All my excuses aside, any feedback is welcome as I'm still at a point where it's relatively easy to change things.

If you ever purchase an stl file of mine, please feel free to print as many as you like. For a lot of my work, that is really the point. Many of the models I have designed are things like cones, barriers and signs, where you need lots and lots of them. I don't really mind people printing them for friends either... but if they are selling other peoples models without permission on eBay etc, or, worse still, re-selling the .stl file that feels like exploitation. That said, I feel pretty strongly against any attempt at Digital Rights Management. I would rather release my models on an open-source license than adopt anything involving key chains or clouds.

Perhaps they are using Speedpak, or something like it? I see a lot of sellers on eBay sending parts for next to nothing. The service I mentioned above used Fedex. That really hurt!

Thanks, that is very useful - and the BR118 info too. If the class 50 bogies are viable, that's a starting point - when its released at any rate.

Thanks for that, I did wonder about the wipers and airhorns. The prices look very reasonable. I will have a closer look at the coupling cut out. The drawings seem pretty good, but it may be an issue with my lining up the side and front elevations. I have shaped the lower body now, which may make a difference to how it looks. In any case, I can still freely adjust the cut out without breaking anything else, so it's great to have that feedback. --------------------------------------------------------------------------------------------------- EDIT: You were right, the cut-out was well off!

Just a little progress update before I knock it on the head for tonight. Starting to get some of the details in. I think I need to address the curve along the bottom of the body next... I probably should have done this earlier. This side-by-side was to look at the panels on the nose, and to get another view of the windows. I was finding these hard to get from images, but there are a few videos of 55009 going under bridges and these were really helpful. That said, the images I have been using are from it's last days in Finsbury Park when it had the white cab, which is why I blanked off the head code panel. I was about 9 years old at the time.

I have looked at the BR118 co-co... a search for 47290 shows a comprehensive list of spares. It looks like the bogies are available complete, and the dogbone shafts and motor with drive cups are there too. It looks like that could be a viable option. I'm favouring the class 50 at the moment because I will want one anyway and at that point I will have one in hand to measure up.

Thanks, I hadn't seen that. I'm going to plod on with my own design though as I'm quite enjoying it. I'm going through a mass of images and youtube videos and they are a pleasure to study. I'd also like to have my own .stl for this. When I do get to see the class 50 chassis, I will inevitably want to make adjustments.

Hello, I'm having a go at a Deltic in 1:120 scale and I thought I'd post my early work in case anyone has any useful feedback. No idea about the chassis yet... to be honest, I don't even have any track yet, so running it remains a moot point for now. I have been working from the plans in British Rail Main Line Diesel Locomotives 2nd ed. by C. Marsden and G. Fenn, and a fair bit of eye-balling from Flickr images etc. Apparently a real one came through Hornsey on Thursday, but I missed it... hopefully, I'll get a chance to see it on Sunday.
