Benn- In my experience keeping SCLTC trains running for the last 6 years (including a 10 week, 6 day a week show every year), what kills the train motors is erosion of metal contacts that pick up electricity from the rails. The contacts wear (...) (19 years ago, 10-Oct-07, to lugnet.lego, FTX)

| (...) You are right, the main limitation probably comes from wall wart... You are essentially right for the 0.7A current (though it is not hard limit, rather a safety one). Philo (19 years ago, 9-Oct-07, to lugnet.lego, lugnet.robotics.nxt, lugnet.trains)

| (...) The Australian LEGO wall wart is marked 10V @ 7VA on the secondary. I don't recall all the stuff I learnt about the relationship between VA and W, but that seems to me to indicate about 0.7A. I believe this generally reduces as load increases, (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt, lugnet.trains)

| (...) Philo kindly corrected me, pointing out that the NXT outputs are regulated down to 1 A, so you couldn't run a dual-truck train all the way to stall. You could still get a good bit of the way there, however. Does anyone know what the peak (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

Out of curiosity, along with the output limitations on the NXT (1 A) and RCX (500 mA), does (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)
