Layout about 20 ft long by 12 ft wide double decker.have about 12 engine on two main lines and a bunch of siding.i had one 180 brick power the whole table but have added about 6 or 7 more engines and now it seem to pop the breaker alot unless I take a few engine off so that's when I thought I could add another powerhouse brick 180 with a lionel lock on but it just shorts out.
