    1 speed regulator 2 trains and tracks —Eben Hill
   Is there any danger in hooking up one regulator to two sets of track with two of the wires that clip to the track. I tried it out and I know that it works but wasn't sure if this was a "legal" thing to do or am I going to end up blowing up the (...) (25 years ago, 2-Dec-98, to lugnet.trains)

     (...) I don't know if it is 'safe' or not, but my kids often use the speed regulator to run the various (non-train) LEGO 9V electric items. Steve (25 years ago, 2-Dec-98, to lugnet.trains)

     (...) just (...) I think it's pretty much impossible to damage the train controller no matter what you do to it [1]. Lego expect people to 'experiment', that's the whole point of Lego so you can be sure that if you can build it, it will be safe. [2] (...) (25 years ago, 2-Dec-98, to lugnet.trains)
   
        Re: 1 speed regulator 2 trains and tracks —Dave Jost
     Not an expert in electronics....I think the regulator adjust to the amount of current that is drawn by the motors so two regulators would share the workload on the same system and if you add more motors on the same regulator it would just feed more (...)

     (...) Well, if you draw too much current thru your regulator, You'll most likely run into the limits of the wall-brick trafo thingy. Whgen that starts to get hot at prolonged use, beware :) Jasper Jasper (25 years ago, 5-Dec-98, to lugnet.trains)

     (...) This comes up a fair bit on a regular basis. Someone needs to write up all that is known and get Matt to add it to his excellent site. Anyway here's what I know. I probably have a 1/2 dozen regulators at this point of various histories (most (...) (25 years ago, 6-Dec-98, to lugnet.trains)
    
         Re: 1 speed regulator 2 trains and tracks —Jasper Janssen
     (...) Sounds like a fairly intricate scheme - especially if it automatically goes back to work again, instead of requiring you to replace the fuse, which is the usual option. Good work by Lego, I guess. I'll open mine up one time and check :) BTW: (...) (25 years ago, 6-Dec-98, to lugnet.trains)

     (...) snip (...) Hi All, To add to the complexity, with the introduction of 4519 crossover, will it be possible to have to separate train systems powered by separate controllers which crossover one another, once, twice etc. Mark H. (25 years ago, 7-Dec-98, to lugnet.trains)

     (...) Unless they have foolishly connected the two sets of crossing tracks. Now wouldn't that really suck :) Jasper (25 years ago, 7-Dec-98, to lugnet.trains)
   
        Re: 1 speed regulator 2 trains and tracks —Patrick Gili
   1) The location you clip wires onto the regulator contains two terminals. One of these terminals sources current to a load (e.g., a motor). The other of these terminals provides the return path for current (remember, an electrical circuit forms a (...) (25 years ago, 16-Dec-98, to lugnet.trains)
