Welcome to the forum!
You can use your ZW transformer to power a LionChief train set. Hook up the ZW to the track, and turn up the power to 18 volts and leave it there. The LionChief remote will now control all functions of the train. You must use the remote to control the train. You do not touch the transformer at all.

LionChief Plus sets have a switch that will allow you to either run the train with the remote, or switch to conventional mode and use the transformer to operate the train.

If you set up 2 independent loops of track, you can use one throttle of your ZW transformer to operate the LionChief/Plus set on one loop using the remote, and a second loop connected to a second throttle of your ZW and control your old trains the conventional way.
