    It's a fun hobby. Please remind me if I appear to forget.
    My home layout: http://www.rmweb.co.uk/community/index.php?/topic/120795-south-hampstead/#entry3387669

  1. If you can't follow the diagram, I am not sure a few words will help, but I'll try. It needs an extra power supply for the 16v AC. The output from the controller goes into the pair of terminals marked 0-12v DC in. The track is connected to the terminals marked 0-12v DC out to track.
  2. I am intrigued by that. Why did you find installing catenary after ballast undesirable? I had catenary on a previous layout (& will add it to the modernised version of my current one). I found cleaning track under the wires was quite awkward & expect ballasting would be even more so.
  3. I have felt burned out in the past, but not at the moment. I have several things on the go in the layout room which help me from feeling down. I have spent months, possibly years when I've not even thought about working on a model or layout. Don't worry about it though. Your layout will not walk away one its own & you will probably find your enthusiasm again..& if you don't, you will find another issue to replace it. I still keep in touch with my club via video calls but it is not the same & I get a strong feeling that many have lost the enthusiasm that meetin
  4. Why is that a no for most people? I read Nigel's comment & thought the complete opposite: Feedback or PWM controllers are less common & therefore less of an issue than they used to be. High frequency track cleaners can be removed without too much difficulty if running DCC-fitted locos is a requirement. Small capacitors are good for interference suppression but most electric motors tend to run better at slow speeds with a slightly pulsy supply, so using a capacitor to smooth this out may be counter-productive when running DC locos. Decoders contr
  5. There is no need to guess: there is a convention. When wiring DCC, there is a mnemonic "red & black to the track, orange & grey go the other way"...the other way means the motor, but that doesn't rhyme. Remove the board but leave enough of these 4 wires to identify them, or if required, connect them together. Connect red to orange & black to grey. If the manufacturer wired the loco correctly, it will now run in the correct direction.
  6. The 91's pan should have a narrower base. The loco was designed with a tilting tumblehome so the roof is narrower. I can understand why the 87 pan is so flimsy. Hornby took a choice between making it work or making it look good. They made a working one before & this was very overscale. I am sure they could have made a better attempt but they chose to make one which looks good (& in photos I cannot deny that it does look good). Some have commented that the pan on Bachmann's 90 looks poor, but the BW pan is a delicate prototype & this is the compromise they took by g
  7. That is only 1 point of view. The APT's problems were resolved. It failed for political reasons, not technical ones. If you were a senior BR official, would you admit that the APT was a management cock-up, not a technical one? I certainly wouldn't. It was initially introduced into service before engineers were ready. The project had taken so long that management were keen to show their progress. The project costs had grown enough to attract attention to the project so management wanted to show its progress. It was therefore pressed into service prematurely with lots of me
  8. Yes, I have mine in a tool box. The tool tray at the top has a DCC track on one side & a DC on the other. Anything I need like DC controller, Powercab & small multimeter.
  9. Signalling & braking distances limit speed too. The 91s were designed to run at 140mph & this was trialled but while this sounded great, in practise they could not maintain it. The problem was they would catch up with the train in front too quickly.
  10. I don't know the answer but I understand why it is not working. The decoder is trying to keep the exhaust beats in sync with the wheels. It does this by detecting something connected to it which is linked to the wheels - the motor. Since you have no motor, it cannot detect it, so produces no exhaust sound. Diesels are unaffected by this because the engine sound is not in sync with wheel revolutions.
  11. HST as designed to run regularly at 125. You would not expect any vehicle to reach its absolute maximum speed on every journey. It is quite understandable that they can go much faster if pushed. That is similar to Mallard doing 126 in 1938, then promptly failed with an overheated bearing, which is why its normal service maximum was about 90mph. You still hear of people claiming there has been no progress 'because modern trains don't go faster than Mallard'. What constitutes a diesel? Didn't the APT-E use diesel fuel, but with a turbine instead of internal combustion? Jet
  12. Great video, Mike. Your previous video about cleaning blocks not scratching rail surfaces was a real eye-opener & dispelled the myth that many have been spreading for years. It was nice to see a discussion based on what you observed & showed through your microscope. After seeing that, I'll be ditching my meths in favour of white spirit.
  13. As above, plugs or a DPDT switch. Either will make it completely impossible to connect both systems at the same time. It may not be you who does it. You may have a friend round who does it without understanding how you have set things up.
  14. You've hit the nail on the head there. TMDs are not disliked but they are often modelled in unrealistic locations. A small branch line terminus is a common choice because it can be squeezed into a smaller space but, since the 60s, most consist of 1 or 2 platforms & little else, but this is not he way they are usually modelled. A 'rainbow of class 66s' is nice to operate, but they would come from the main line, which is where the TMD would be. What period you want to model makes a big difference. The traditional mixed goods yard was phased out around the same time
  15. It is all very well saying "stop that" but you need to provide an alternative & does anyone arguing against them seriously believe that planners are too stupid to not have already considered potential alternatives? Of course they are not. They can provide very good reasons why wind power is currently the best option, but the nay-sayers are too narrow-minded to believe it.
