  1. Sorry, for some reason I thought you were using polycarbonate. D'Oh!
  2. Yes, my preferred supplier says that wood drill bits are OK in polycarbonate: https://www.cutplasticsheeting.co.uk/product/clear-polycarbonate-sheet/ (click on FAQs) It also says that polycarbonate can be "cold curved" and cautions against heat forming unless the material has been oven dried beforehand. (I haven't tried cold curving yet - you'd instinctively expect it to snap at tighter radii!)
  3. The layout has a built-in Pi-Sprog DCC controller that will allow wired or WiFi connections to any JMRI compatible throttles for driving. This makes it a self contained unit, needing only an external PSU to be connected. (The old Gaugemaster Prodigy controller I used earlier to test the track wiring is now back in the loft.) The Pi-Sprog and the Megapoints MTB controller need 15V but the Pi only needs 5V. I didn't want to have to carry multiple PSUs around with the layout so I bought a 15V 4Amp PSU from Rapid to power the whole system and I'm using a 7805 voltage regulator to get t
  4. Dremel with right angle tool attachment and a diamond slitting disc for perpendicular cuts: https://www.dremel.com/gb/en/p/dremel-right-angle-attachment-575-v224 Plus, very importantly, eye protection! You can guess how I know...

      But how many are unique, and how many are the banned returning under a new nom de l'adhérent?

      It doesn't matter. It's an arbitrary number like so many others in life.

      I thought you were on about the Traffic song:

       

      "Forty thousand headmen couldn't make me change my mind
      If I had to take the choice between the deafman and the blind
      I know just where my feet should go and that's enough for me
      I turned around and knocked them down and walked across the sea"

       

      but I suppose I'm showing my age ...

  6. No concrete? Just held in place by the ballast backfill?
  7. Here's one source that I extracted some bell sounds from a while ago: It's interesting that the people in the box seem to be griping about management and the world in general and when someone called "Mike" rings up the tone changes somewhat...
  8. The bottom most section of the station: [Parcels & milk, loop, cattle dock, coal siding, goods shed, goods loop and brake vans siding] forms an isolated, non-passenger-rated area. So I don't think any ground signals are needed for movements within that area at all. I suggest only ground signals for the two crossovers to and from the passenger-rated P1 line would be needed and only for three of those movements because the move from loop to P1 loco release would never happen during normal operations. What do the expert signallers think?
  9. In the cold light of a new day I can see that there is, of course, a better answer: Abandon the turntable. Then there would be many more possibilities to arrange things. Your current plan would work but my suggestion would be with one less goods siding and without the stub branch, which is just too "tricksy" in my book.
  10. Thanks for the new photo and clarification of the dimensions. This is my best suggestion to keep the engine shed and turntable connected that would work within the tight constraints of the existing baseboards: Two bridges cross the river, maybe stone in front and timber trestle behind. No branch line and no private industry but that's OK - less track and more room for non-railway scenery and buildings.
  11. Electrofrog definitely. The plastic frogs on Insulfrog look ugly, cause stalls and they will wear down eventually. Electrofrogs need a bit more preparation than Insulfrogs if you are going to switch the frog using an external switch and there's a related modification you can do to them to make the blades have a more reliable electrical connection. Did you mean crossover rather than crossing? With Electrofrog turnouts you have to use insulating joiners in places, simply because the frog, and the V rails connected to it, change "polarity" when the turnout route is changed
  12. Schematically, like this: or maybe like this: I don't know if they would fit when curved into your space. You said above that the space was 10ft by 6ft 6in. Does the 6ft 6in length already include the doorway?
  13. Regarding reach: Remember that you need to be able to work at that distance comfortably for long periods, not just reach it momentarily at a stretch. And the more scenery there is at the front, the less room you have to put one hand (or foot!) down to steady yourself and reach further. Maybe three goods sidings would be enough? 1. Cattle dock and Goods loop. 2. Goods shed, <yard splay>, 3. back/mileage siding. I think the shed and the TT should be close together - I can't think of an example where they aren't. The TT can either be on the line into the shed (e.g. W
  14. That gives you a lot more work to do and makes things a bit more difficult and more costly. I wouldn't bother - certainly not until the proper scene is well-developed, which will take a lot of time and effort. Sensible fiddle yards are usually seen. By definition you need to be able to fiddle in them... A hidden storage yard (not a fiddle yard) needs a lot more infrastructure than a simple open fiddle yard. Some or all of: special access for emergencies, cameras to see what's in there, fully motorised point control, occupancy detection. My preference is for
  15. This is a big project and it needs to be approached stages. Point motors: Yes, there are lots of options and I'm about to use MP1s on my Minories project but Dougie was asking about point motors in the fiddle yard where the requirements are that they can be surface mounted and fit in the restricted gaps between tracks without fouling rolling stock. Are there any slow moving products that meet those requirements? Signalling is easy: I don't think there is any. Probably not even any ground signals. Nothing is shown on the map. Points were probably all operated by hand lev
  16. There's still too much track to my eye, I'm afraid. The splay in the goods yard doesn't leave enough room for lorries to back up to the loading bay. The turntable is in an odd position away from the engine shed. The baseboards are 3ft deep and so it might be difficult to reach the back when all the scenery is in place. The far corner will be very difficult to reach. I'm worried that the operation of the branch line stub will be unsatisfying. Trains will just stop and stand in the valley and they will inevitably be visible from some angles, destroying the illusion that they'
  17. Sorry I'm a bit late to this but: How about using an M8 captive nut, hammered or screwed into the baseboard with maybe another in the sector plate? Then wind the bolt down through them both, leaving a small gap and fix the bolt to the plate with a nut on top. The bolt will turn smoothly and accurately in the captive nut in the baseboard and the amount of vertical movement would be tiny for a 30° movement - and that movement is away from the track joints so wouldn't affect them. (Might need a bit more timber glued underneath to give the captive nut a so
  18. I have an image of poor old Uncle Hornby: Trying so hard to be "modern" but doing it in his own stuffy old way, not getting it right a lot of the time and falling out with his best friends.
  19. Possible combination to start off your research: Peco PL-11 point motors + Megapoints solenoid controller + Megapoints DCC module.
  20. Sounds great. That's a relief! Yes, they might be a good solution. I have heard they can be a bit finicky to set up, requiring careful alignment, and they are quite expensive but they would certainly fit alongside most of the ladder turnouts and require less cutting and fiddling underneath.
  21. I think moving the FY turntable will lose a lot of storage capacity because it will take up space that you can't regain at the other end. It fits into a natural space on my drawing. And I would suggest keeping the doorway as open as possible. I had a nasty thought in the night: Have you insulated the garage? Are you going to? The extra thickness inside the walls could have a serious impact on the design.
  22. Thinking about baseboard construction, here's my suggestion for handling the level changes. This is just the baseboards layer from the (revised) drawing. Darker is lower, lighter is higher. Everything is fixed apart from the lifting flap and "manhole" (dotted red outlines). The lowest area on the right might simply be open frame. Most of the shed pointwork is on the irregularly shaped board that stands above the open frame.
  23. Yep, the reason I didn't do that was that, apart from the bridge across the operating well, the turnout leading to the return loop would have to be in the scenic area, which bothered me but may not bother Dougie so much.
  24. That extra line would certainly work technically - the pointwork could be slotted in very easily. You could leave a train circulating while operations continue in the shed, using the South outbound line as a headshunt if needed. But since running coal trains through the shed area is not prototypically correct anyway then you could run them around the circuit already provided. Most operations in the shed could still continue - even coaling tower movements have enough room to continue. So the new line doesn't really gain much and the cost is even reach problems to the bac
