Ok I got a problem and hoping someone can help.im trying to add more power to the layout.here what I got.i have one 180 power brick and it doesn't seem to be a enough power to the layout when I power up.pops the breaker alot.i have alot of engines on the track.so I bought a lionel lockon and hook up another 180 brick but it just throw the breaker.i know its wire correctly. So I'm not sure what to do.someone told me to split the table up by insulate half the table and put one power source on one and one on the other.if I do that what when a train crosses the insulate area. I just learn about a lionel tpc 400.maybe I should get one of thoses.any idea ????Help!!!!
