deepeg59 Posted November 11, 2020 Share Posted November 11, 2020 Any advice on running an n gauge loco on track powered by a battery pack. It is only for a very small train -loco and 2 wagons - on a Christmas scene where speed should be very slow and does not need to be variable. I don't really want to use a standard controller for safety as young children will be watching/using it and it would be more portable. Would only be used in short bursts and the loco is 'old'. Thanks for any comments. Link to post Share on other sites More sharing options...
RMweb Gold ikcdab Posted November 11, 2020 RMweb Gold Share Posted November 11, 2020 A battery pack will be fine, it depends on the power consumption of the loco and the power of the battery pack. A "wall wart" might be better. Ian Link to post Share on other sites More sharing options...
DCB Posted November 13, 2020 Share Posted November 13, 2020 Basically if its rechargeable batteries don't do it. They can deliver a very rapid discharge if shorted out, real potential for starting a fire. I used AA rechargeable batteries in my OO garden railway locos and melted a body when I had a trapped wire short out. Bog standard poundland 12 pack for £1 AA cells are fine. Wall warts are the industry standard so why reinvent the watering can? Link to post Share on other sites More sharing options...
AndyID Posted November 13, 2020 Share Posted November 13, 2020 You could use one of these https://www.ebay.co.uk/itm/Triang-Tri-ang-P-40-Vintage-Power-Unit/164094122346?hash=item2634c5996a:g:EJoAAOSw~QVeRUiv&redirect=mobile but I doubt if you can find the three bell batteries it needs. (That thing must be at least 60 years old). Link to post Share on other sites More sharing options...

RMweb Premium rab Posted November 13, 2020 RMweb Premium Share Posted November 13, 2020 What goes round comes round. My first set 65 years ago had a controller which used two big 6 V batteries. Link to post Share on other sites More sharing options...
Grovenor Posted November 13, 2020 Share Posted November 13, 2020 A 9V PP3 battery should do it. Link to post Share on other sites More sharing options...

They were out of stock last time I looked at least a couple of years ago 1 Link to post Share on other sites More sharing options...
