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!

Not sure of how much track you have, so we'll go basic(KISS) with a 72 in. radius circle of track. You have one 'lock on' at the 6 o'clock position of the circle, when your locomotive reaches the 12 o'clock position on the circle of track it slows due to power loss. You place an additional 'lock on' at the 12 o'clock position on the track and the locomotive no longer looses power. Simple, 2 wires to each 'lock on', 4 wires total hooked to your power supply....... Runs well, so you decide to a 20 ft. of straight track to each side and you get power problems again.... so you add another 'lock on' to the 3 & 9 o'clock positions, hook up wires and successfully run your train. But..... Now you've got a bunch of wires trying to be attached to your transformer. Here's where the power buss comes in, you take the 8(4 pairs) wires and insert them into one side of the buss, then run 2 wires to your transformer from the buss supplying power to all. I hope this helps. Happy Rails! Dave *****************************************************
