Ian-1317656 Posted August 1 Share Posted August 1 Hi all first post, first credit and reference to Warwick’s. Post in 2019 in relation to my question Side not first just bought latest Hornby Flying Scotsman 21 pin with steam love it to question peco 10 e point motor works on table from a ancient Hornby Mecanno The AC outputs 19.5 It also works pushing points on track when I wire directly to one individual point from under table but the BUS accessory line will not even operate the point ( using powercab) in fact if I wire the NCE powercab directly as a main power source to Point motor while holding point in my hand so no resistance on motor. It won’t switch So if I understand Warwick it is not going to and I should not try problem then is the power cab does not provide a aux port do I need to get a separate power supply if so can I get advice on which one to purchase the meccano one I have is very old and I don’t trust it to not catch alight eventually For interest is a Hornby II power control unit Pic attached for amusement purposes anyone know how old this could be Link to comment Share on other sites More sharing options...
What About The Bee Posted August 2 Share Posted August 2 (edited) 3 hours ago, Ian-1317656 said: anyone know how old this could be Yes. Hello Ian and Welcome Aboard. The power controller appears under two names, Marshal II and Hornby II. Identical case and configuration. Late 1950s to 1960s.

dBerriff Posted August 2 Share Posted August 2 You need to be careful with these old power supplies. They are from an age when wire insulation could break down over time. 1 Link to comment Share on other sites More sharing options...
Bulleidboy Posted August 2 Share Posted August 2 I inherited one of those controllers and it went straight in the bin. 1950's technology - to risky. Link to comment Share on other sites More sharing options...
Brew Man Posted August 2 Share Posted August 2 Ha! I had one of those power supplies. Yes, 1960. I was always a bit disappointed that the speed control went in steps rather than smooth increments. Link to comment Share on other sites More sharing options...
ntpntpntp Posted August 2 Share Posted August 2 (edited) I'm a bit confused by what you've written about the point motor? Are you trying to operate the solenoid point motor over DCC using an accessory decoder connected to the motor, or are you simply trying to use DCC power and push buttons or a toggle switch to fire the point motor? For it to be switched using DCC it needs an accessory decoder. I wouldn't waste the available DCC track power from the PowerCab to provide raw power for point motors. If you're not operating the point motors via DCC then use a separate power supply (preferably about 18V) and a Capacitor Discharge Unit (CDU) which will allow a strong but brief "thump" of power and then protect against burn-out if the power is on too long. Use momentary switches or push-buttons. Edited August 2 by ntpntpntp Link to comment Share on other sites More sharing options...
Barry-350851 Posted August 8 Share Posted August 8 Only worth getting these old supplies reconditioned if you are using 3-rail or Dublo that was contemporary as they seem to have the kick to get them going. Link to comment Share on other sites More sharing options...
ColinB Posted August 8 Share Posted August 8 I bought a DCC Concepts unit and was very surprised how good it is. Link to comment Share on other sites More sharing options...
