  1. Given that the bar is attached to the upper deck structure, it would be a bit pointless if damage due to 'flimsiness' were the risk being mitigated...
  2. It was the voice-over narrator, not the MOM who used the words "trick of the light". The MOM did mention that the sun had been shining but he didn't say anything (that we were shown) to suggest that he thought that might have been the cause of the couple's mistake. (And the on-train CCTV did confirm that they had been mistaken, clearly showing that the barriers were down when the train in question passed.) Given that, according to the woman, the incident occurred at 10:58* (you may need the subtitles enabled to catch that) - and it doesn't seem to be autumn or winter since all th
  3. I was going to add "This is not taking inductance in to account" but decided not to muddy the waters as I was replying to kevinlms who specifically mentioned resistance and voltage, and did not mention inductance, and in that regard his assertion that a lower resistance would "take the lion's share of the voltage" was simply wrong. But thank you for clarifying why a difference in inductance - which you have measured - can give rise to the results that the OP is seeing.
  4. Hang on. If the coils are in parallel then they will both see the same voltage regardless of any difference in resistance. If they're in series then the lower resistance coil will see a lower voltage, since the current will be the same through both coils (by Ohm's law).
  5. Do they? I can't say I've ever seen such a claim, and I've certainly never seen anything like a published standard for tension locks on UK railway models. If any such thing does exist it would be of passing interest to see it. I get the impression that the situation regarding tension locks is much looser than that: the manufacturers all fit their stock with one or more variants* on the general tension lock theme, and people blithely assume that because they all appear to be intended to function in the same way then they will all happily interoperate. Given that at least one of t
  6. Another way to avoid such issues is not to use a hammer for pinning track, use a pin pusher. It's what it's designed for. https://www.ebay.co.uk/itm/Pin-Pusher-With-Depth-Stop-PPU8175
  7. I would regard conductive grease as grease that happens to be somewhat conductive, rather than a good conductor that also happens to be greasy. And that's before you get in to the question of applying grease to (or close to) a surface on which you will be relying on metal-to-metal contact for traction...
  8. How about an old-style ¼" headphone plug and socket? These were/are used for connecting electric guitars, synths etc to amplifiers are are designed to be connected and disconnected frequently during their lifetime. They're pretty cheap, and although they aren't often found in non-specialist shops they're very easy to buy online. I'd suggest a panel-mount socket on the baseboard somewhere, with the plug on a coiled lead back to the controller. (FWIW I use a 3mm headphone plug & socket for my 'scratch' layout and they work fine.) Assuming it doesn't fry the cable fr
  9. I think AndyID is referring to this kind of arrangement within the terminal block: where the metal plate completely covers the tip of the screw so there's no chance of the thin cores within the flex getting mashed up by the screw as it's turned. Although the photo on their web site isn't clear enough to show it, I think this terminal strip from RS Online has that kind of construction: Nylon 6.6 Terminal Block With Wire Protection Leaf. "This RS PRO terminal block also features metallic wire protection strips that isolate the conductor from the terminal scre
  10. More than a little harsh IMO. As kevinlms indicated a few days ago, plenty of people use electrofrog points out-of-the-box without ever experiencing major issues. Crewlisle of this parish for one, who has a pretty complicated exhibition layout and who used to pop up whenever this topic was raised (which feels like it happens several times a year) to point out the lack of problems he gets from doing so. ISTR that he attributed this primarily to scrupulous track cleaning, which should arguably be standard operating practice anyway. (I wouldn't be surprised if the reason he's not appeared on
  11. If you're referring to the radius of the turnouts, Peco quote the (nominal) radius of the code 100 and code 75 medium radius turnouts as 914mm (36"). The small radius turnouts are quoted as having a nominal radius of 610mm (24"). They are non-magnetic, but unlike the rest of the coupling, the hook is not plastic. You can scrape or sand the black coating off to reveal the shiny metal underneath: This might be useful if you wanted to adopt the Brian Kirby automatic uncoupling method (Google for details) as, depending what the metal actually is, yo
  12. It should be streamable on ITV Hub (although they can be a bit flaky with the actual process of making shows on the 'lesser' ITV channels available online).
  13. Bear in mind that if jumpers are fitted between stock and switch rails then the frog must be isolated from the switch rails (otherwise you'll get a dead short) which in turn means that power must be provided to the frog via an external polarity switch synchronised with the movement of the tie bar.
  14. Just so long as they don't make the tightest part of the curves smaller than 2nd radius in order to accommodate the extra length required for the transition curves within the space occupied by a normal 2nd or 3rd radius curve. You still need more room for transition curves even if the main body of the curve is still at your chosen minimum radius.
  15. This YouTube video features brief clips of the original Blue Peter model railway through from 1962 to 1994, and its replacement: As you say, the original layout didn't have much in the way of scenery. Its successor was rather more thoroughly sceniced, but still isn't the one in Endeavour.
