(...) [snip] Hah, and here was me using a 12V Lego train transformer to run my 9V trains ;-) Using a suitable adapter wire of course. But that was 220V, so I left it in the UK. I'm not sure of the rating of those transformers, but I think it was a (...) (17 years ago, 5-Mar-08, to lugnet.market.buy-sell-trade, lugnet.trains)

(...) Here's a couple of useful power supplies. They work on US line voltage or from 100V AC up to 240V AC. For unmodified train controllers: (URL) You should get close to the maximum amount out of you controller, but the controller well overheat if (...)

(...) True, but you still have to upgrade the diodes, capacitor and the power supply. As well as adding more heat sinking ability. And the 3 amp version of a LM350 can swap right into the original socket of the LM317, and still provide full (...) (17 years ago, 5-Mar-08, to lugnet.market.buy-sell-trade, lugnet.trains)

(...) I am not sure if it would work, but it may be possible to use a power transistor to increase the amps. The heat sink will need to be upgraded to a larger size, and a fan will definitely need to be installed to compensate for not just the (...)

(...) The main component that is limiting current in a standard train controller is the transformer (wall wart). The supplied transformer form LEGO has varied between 500ma to 850ma .5Amp and .85Amp respectively. That's continuous duty. You can pull (...)

(...) One of the big modifications I do is install a fan pointed directly at the source of the heat but the neat thing is the speed of that fan adjusts to the power setting of the controller while always spinning the correct way. I am also going to (...) (17 years ago, 4-Mar-08, to lugnet.market.buy-sell-trade)

(...) Hi Ondrew, More power sounds nice, but I'd be even more interested in a controller than can run high-load trains all day (such as at a show) without running hot. It sounds like you're advertising this benefit as well, so I might be interested. (...) (17 years ago, 4-Mar-08, to lugnet.market.buy-sell-trade)

Hey all, I have been looking for new ways to help out the community much like I do with my custom track and I was wondering if there may be some interest in high amp train controllers much like the ones some train clubs all ready use.
