  1. I've never used it, so can't comment on its effectiveness, but there's a product called Bullfrog Snot which you apply to the groove, which solidifies and gives grip. https://www.petersspares.com/bullfrog-snot-1oz-jar-liquid-traction-tyres.ir
  2. "DCC Ready" is a term widely understood within the industry to mean fitted with a DCC socket of some kind, a blanking plate, and No decoder at all.
  3. Humble apologies if this has been covered before. What were the bogie chains for?
  4. Some commercial chips for use in ripple-counter circuits: http://ww1.microchip.com/downloads/en/Appnotes/Sensorless-Position-Control-of-Brushed-DC-Motor-Using-Ripple-Counting-Technique-00003049A.pdf https://www.ti.com/lit/ug/tidud30a/tidud30a.pdf?ts=1599591806554
  5. The problem there is the headroom - alright for Anne Boleyn.
  6. Resistance is futile - or I'll choke you
  7. If it's still available, I'd like it. Have sent a PM. Mike
  8. That depends on what the modeller wants. They may prefer the sounds experienced when riding - or they may prefer to reproduce what the prototype sounded like from the platform / lineside. A well-known provider of sound decoders offers a decoder for the Class 68 diesel, and claims it is accurate, as it was recorded in a train on the move. It sounds nothing like a Class 68 working hard under acceleration. The most pronounced component of that sound is a very distinctive rapid series of loud explosions from the exhaust, such as can be experienced close to a Chiltern train climbing the incline Northbound on the approach to West Hampstead, or pulling away Southbound from Banbury. Here are some examples - bear in mind that no replay loudspeaker gives anything like the full effect of standing beside these units as they take off.
  9. Is something getting too hot? The power supply, the central DCC unit, the decoder, too many things running, a low-level (low amps) short-circuit somewhere...
  10. My friend endured lifelong shame for a debilitating condition - until a genuine therapist got to the bottom of the problem, and he began to understand that he was feeling "blame" for something that was actually largely outside his control. The relief of knowing this, and the support from an experienced therapist - in this case helped by medication, allowed him to turn the corner. I wish you the same support and relief.
  11. I haven't had one that's been problem-free. So much so, that I don't look at Hornby Locomotives now. Mike
  12. If you are installing the decoder into a loco with a pre-existing Plux22 socket provided by the manufacturer, then hopefully, they will have connected the Stay-Alive pins to some convenient points on the circuit board to which you can solder the capacitor leads. If you are installing the decoder into a loco with no pre-existing Plux22 socket, then you could obtain a "breakout board", and solder the capacitor leads, and everything else, to the breakout board. You need to find a breakout board with suitable dimensions to fit inside your model. Some example boards: https://www.ebay.co.uk/itm/224025839775 https://www.esu.eu/en/products/accessories/adapterplatinen/plux22-adapter-board-1/ https://www.conrad.com/p/tams-elektronik-70-01035-01-interface-adapter-assembly-kit-wo-cable-incl-connector-404211
  13. When running two motors from one decoder, what are people's opinions on wiring them in parallel or in series? How well does Back EMF work in either case?
  14. A review on ebay: https://www.ebay.co.uk/usr/johnnyi_uk
  15. The conveyor system, operating over a distance of 1.37 miles on the Avonmouth side of the river, was the cause of the problem. Smuts could be seen on washing lines.
  16. Good Riddance to the BBHT. Assurances were given when the thing was installed that it would not generate significant coal dust pollution for the residents of Avonmouth. False. My poor old Mum was constantly having to clean a semi-permanent black smear from the windows of her house. Heaven knows what particulates were in the air people were breathing.
  17. Would be interesting to find out what the average journey time/length would turn out to be. I wonder if the cheap fares apply if you change at a junction from one Coop train to another - could you get a through fare or would you have to buy two tickets.
