Just fooling around, I decided to run all four of my LionChief Plus locos at the same time. The entire layout is powered by a single CW-80 transformer. Even with smoke units on, the CW-80 had zero problems. This leads me to believe that the LC+ locos are very low power-demand machines. Here is what was powered up drawing from the single CW-80:
Four LC+ locos, with smoke on, 3 steamers and 1 diesel.
Five lighted buildings
Six Lionel remote-control turnouts
Four Lionel lighted passenger cars from FT train sets
One RMT lighted caboose
I have to admit to being impressed that a single CW-80 can power all that.
