What basic electronics does a beginner need to get started with running LIONEL LEGACY engines?

Although it can seem intimidating, you don't need any special programming skills or advanced computer skills in order to be able to install and successfully operate either of the major command control systems, like Lionel's Legacy or MTH's DCS systems.

I'm sure you'll get a lot of varying opinions, but IMHO, for a simple, basic command control set up I would recommend a basic AC transformer such as the Lionel CW-80 or MTH Z1000 and, since you already have a Legacy engine, you'll want the Lionel 990 Command Set consisting of a base and remote.

Hook-up is pretty straightforward, but you can come her for any advice if you get stuck. Like most things, once you take the initial plunge, it starts to get easier as you use the system more. There are a number of you-tube videos which show the initial set-up and how to get started with the Legacy system which I would recommend you should watch.

Everyone here was a novice at one point, so don't feel intimidated.

You are over thinking it.  There is no software programming required.

The legacy controller is like anything else.  You learn what the buttons do and that's it. 

You can enter any engine information into it manually if needed.  The Legacy book may look overwhelming at first, but if you just read it and then go to the remote and try the different functions, it is quite easy.  

You just need the Legacy 990 system and a 135w or 180w powerhouse or instead can just use a transformer like a CW-80.  You just need 18v to be supplied for track power and you can be up and running.

The legacy system has one wire that connects to the outside rail of the track and that's it.

Depending which track system you choose you will just need to connect the Powerhouse to the track (cut off connector and attach the wires or get an adapter (molex connector on one end and bare wires on other, so you don't have to cut off connector).  Or if using a transformer just connect wires from transformer to track.

You don't need anything else for a simple loop to get up and running.

But once you do watch out, it is addictive!  You will want more Legacy Engines, haha

Everything above is correct but you may find watching a YouTube video more helpful as you can follow along with the video. Here is a great playlist of how to setup and use your Lionel LEGACY system which I found very useful when I was setting up mine.  Good luck!

Thank you very much for the responses  and assurances, I will start with the video and thanks for the advice on the legacy system to buy.  Will start working on acquiring parts with power pack first.  Bryan
