  1. The Elegoo filters they have added to their newest printers are simply an activated carbon filter but I don't know how effective they are, I've been using water washable which perhaps goes against percieved wisdom but I've had very few issues with
  2. David, perhaps with your higher quality image you can tell me, is there some carving above the frame of the first floor central window ? in one picture I have seen it looks as if there might be, but it could just as easily be an effect of sunlight and shadow as I cannot see any evidence in other pictures, including the one I have that shows the clock house with the clock yet to be installed
  3. Sometimes I'm far too clever for my own good, I mentioned above that I thought the Kleine Scheidegg station was built to the same pattern as the others, lo and behold I discovered a picture that shows that I was probably right, Now I might be wrong here but it looks to me like originally a second of these buildings was place next to the first just slightly higher. This I believe was what they called the resoration hall built to improve the catering facilities in 1895, it may always have had a slightly higher ground floor, you will note there is no sign of the Jungfraubahn, since that was started in 1896 we can probaly date the picture to 1895 or 1896 :-) Now I'm not sure if that second building was then added to - extensively, or if they moved it across the tracks to form the core of the building opposite, alternatively it's possible that the building opposite might just be the original Wengen Station, certainly the Grindelwald end of the Kleine Scheidegg restaurant has a masonry construction of a similar style to the ground floor of the Wengen station which would suggest it being built at a similar time, the new Wengen Station was opened in 1908 and I can find references to building work at Kleine Scheidegg in 1919 and 1921 - By the way up until 1948 Kleine Scheidegg had a small turntable as seen in the picture on the left, but in the first of the new BCFhe 4/4 arrived in 1947 (No.101) which was too long for the turntable and so the reversing Y was built into the mountainside. most of those 1947 trains lasted until 2015 One final note on these buildings, it is possible that there may have been another at Grindelwald Grund, however the station was moved in 1900 and the original station building destroyed in 1938 for a new carpark, Brandegg station was not constructed until 1904 so got a different style building and Salzegg was not there until 1957, I am not sure on the Wengen side why Allmend an Banwald only got huts (possibly because there were no buildings/hotels at either location) but I believe Wasserstation was litterally only there to take on water for the steam trains, Banwald used to be the start of the winter sledge run but this was later extended to Wengeneralp and in 2002 with the addition of a footbridge to the rail line at the former Wasserstation the sledge route changed again, this was done so people skiing the Lauberhorn race track, would not have to worry about avoiding sledges which used to cross the piste right above the drop off to the Wasserstation Bridge Hope someone finds that little bit of history/speculation interesting - David
  4. razor saw and a facemask plus a sharp knife and files/sandpaper (plus facemask) resin dust can be very nasty
  5. Ah yes I see them in the new video, looks like they are in danger of missing the train LOL
  6. Did the ticket machines etc come from https://www.swissmodelrail.ch/ or somewhere else ? I only ask as that is the only place I have seen that sells the little ticket validating machines
  7. Assuming it's set between mid December and the start of April there really ought to be at least one person carrying skis, if you go to Arosa for skiing you get a discounted fare on the RHB I believe this year for example if you have a valid ski pass travel from as far as Tiefencastle to Arosa is free, and the Swiss will often go for a days skiing if they have a day off, I once saw a person getting on the train as Basle at 5:30 am wearing ski boots and carrying skis and they went all the way to Lauterbrunnen which they reached in time for breakfast (I know because I got to Wengen in time for my breakfast and was on the ski slopes by just after 10am)
  8. The Germans during WW2 had similar problems so many of their supply vehicles and much of the farming was done with horse power, fuel being in particular short supply for Germany
  9. If I were closer ... sadly it's almost a 4 hour train journey each way with a minimum £77 return fare ... Ouch Do you just use one of the accessory lines on a DCC decoder to power it ? And I assume that you can leave the power on to keep the pantograph in the down position ? Annoyingly because I plan to use this on a rack rail system with gradients going between 0 up to 20% and back I think I need to include a sprung follower as well, should be ... interesting
  10. Fascinating reading about the memory wire, if I read it right you get about 3mm of contraction for a 100mm wire ?
  11. Technically there are two variations used in software, one is bump mapping where the software simply creates the lighting effect of a bump on a typically smoth surface, the other is displacement mapping where the surface itself is altered by the texture being applied to it, the latter is far more accurate but requires a higher density model which gobbles up more processing power, in the CGI industry it is normal to use both methods with displacement mapping applied to foreground objects and much simpler bump mapping applied to those further back, I could go on but typically it's very boring and theres a lot more to it than just what I've mentioned, Now the imporetant bit for model railways is that because displacement maps change the actual mesh structure you can use the method to take simple 3d models and apply complex textures to the surface before printing them out, 30 years ago such technigues were the preserve of super high end computers, 20 years ago it got into the realm of PC's and now anyone with a reasonable spec PC including a good amount of RAM can create quite complex models at home and print them out
  12. Yup having seen how quick repairs are made on the WAB I will agree they don't hang about, about 35 years ago I was out in Wengen one Easter and a mud slide came down covering the track, I was in Lauterbrunnen at the time and had to walk up, this was about 5.30pm, by the next morning mud and rocks had been cleared, track replaced and catenary wire restrung and it was all working in time for the first train up. It does take a bit longer if anyone is seriously injured but not much longer.
  13. Whilst on the subject of weird technical things about the WAB I came across a technical drawing that puts the height of the WAB catenary at 5M I believe this is slightly lower than many other catenaries, but the JB is just 3828mm from top of rail to wire when on the flat courtesty of a set of drawings from Stadtler who produced the most recent trains, of course the JB also uses twin wires so it's doubly special
  14. Well Brooke Bond PG Tips was certainly a very good (Best ?) seller for a very long time in the UK, interestingly for 20 years the Brooke Bond brand all but vanished and was only reintroduced in 2019
  15. Intresting the urinals look very similar to these victorian ones currently for sale on a well known auction site probably with copper or lead pipes and either a copper, lead or white enamel cistern A quick search suggests that many had the cast iron parts painted green, brown or dark colours, if you have it actually on a station chances are it would have been painted to match colours used on the station itself
  16. Possibly because DXF files are unitless so there is no way for any system to know how to scale them
  17. I just ran the image into Autocad I get an average distance between track centers of 4275mm RHB Coaches are about 2670mm wide behind a GE 4/4 III loco which actually sounds about right to me for the pre raised platform era, I can remember transfering between trains on another line in Switzerland and the conductor opened the door lent out and passed the cases straight across the gap, there was maybe 4 to 5 ft between the sides of the two trains, typically at a station if two trains were expected in at the same time the staff would ensure no one was in the area between the two trains, the new raised platforms mean there has to be more space between the lines which has often resulted in one or more lines being removed in the station area So for European N Gauge is 1:160 26.71mm or 27mm between centers sounds right to me Your problem is that N Gauge track at 9mm = 1440 mm at 1:160 or if using 2mm = 1 ft (300mm) then 1350mm which is significantly wider than the meter gauge of the Rhb I'd get a pair of passenger wagons and space the tracks to give a scale 1.5m between them, that should look right
  18. It certainly is, but don't forget if you have a 3D printer you can print your own test equipment so you don't need to know the name just have an idea of what it needs to do. I once improvised a measuring setup to allow me to transfer body sizes onto a manequin using a long steel ruller a couple of set squares , some cardboard and duct tape,
  19. I'm going to assume that the curved surfaces are on an existingg loco rather than one drawn by yourself otherwise you would already have the dimensions, I would use geometry to get a rough starting point say I worked out that it was roughly a 20mm radius, I would then (depending on the size) get a set of radius gauges or print off a radius gauge and compare, Your problems arrise only if it's an oval surface rather than a circular one however it is still possible to get close using a contour gauge and a micrometer to take a series of points across the surface, then create some custome 3dprinted gauges to match, or get it laser scanned David
  20. A quick look on Google maps shows excellent shots of Malans (individual rails clearly visible) , Rueun nowhere near as good on Google but https://map.geo.admin.ch/?lang=en&topic=ech&bgLayer=ch.swisstopo.swissimage&layers=ch.swisstopo.zeitreihen,ch.bfs.gebaeude_wohnungs_register,ch.bav.haltestellen-oev,ch.swisstopo.swisstlm3d-wanderwege,ch.astra.wanderland-sperrungen_umleitungen&layers_opacity=1,1,1,0.8,0.8&layers_visibility=false,false,false,false,false&layers_timestamp=20101231,,,,&E=2730294.66&N=1181830.07&zoom=13 has excellent high vis imagery, you can output these pints to pdf complete with a 25m grid which allows easy scaling, Rhäzüns is a bust for both packages, the first two have still got 3 track setups in arial imagery well plus sidings for Rueun, get your hard copies before they update the satellite shots
  21. I trust you have one or two benches to put under the balcony ? I don't think I've ever seen it without either a single red bench or a pair of darker maybe green ones
  22. I'm going through the process of scratch building Wengen Station, every time I think I'm almost there in terms of drawings I find extra information and realise I've made errors with what I have so far. Fortunately I have several friends that can get me pictures when I ask if they are around but I like the high tech modern canopy combined with the early 20th century station building Not a great pic of the station but it shows the 21st century canopy with the 100 year older clock on the roof of the station behind
  23. When painting laser cut wood where you don't want the wood structure to show through a couple of thin coats of white work well as a primer when sprayed on, spray both sides to reduce the chance of wood warping If you do want the wood structure to show through then alcohol base stains are a good option, apply in light coats again on both sides and allow to dry between coats David
  24. In theory the water soluble supports should give the very best support structure with no marks left on the finished print, Will be very interested to see final results post goo as the memorials already looked good from the first batch, clearly showing the advantage of photogramatry combined with a full colour 3d printer
