You can never have too much power available for your trains and accessories! For an older transformer, the postwar ZW at 275 watts input power cannot be beat. With 4 independent throttles, you can run your trains on 1 throttle, and have 3 independently adjustable throttles available to operate your accessories with plenty of power to spare. No need for a separate transformer for accessories if you are running just 1 train.

Hello. New here.
I have once again set up my trains (after many years stored away). I want to run a bigger set up with more track. Hooking up my transformer to one location, as I did way back when, is not cutting it. The train loses power at the more distant sections. I'm very mechanically inclined, but not so "electrically". I have seen some posts about using multiple lock-on's hooked up to a track power bus under the layout. Not sure what this is and how to do it???

Any help or sources that show how to do this is greatly appreciated!
