Another option is to use the dummy as a sound unit.  Instead of a motor and gear assembly, install speakers and a sound decoder.  If you always run this unit with a powered unit, you can have a sound-equipped consist to pull your trains.

Unless you can find a damaged unit and do a shell swap, turning a dummy into a powered unit will probably cost almost as much as just buying a complete engine.  (It is, however, a good modelling experience, if just for the things you'll have to learn to do it.)

On the other hand, putting sound into a typical non-sound engine is difficult, because the designers generally didn't leave space for a speaker.  With an empty dummy shell, you'll have plenty of room for the electronics.  You can even add headlights if you get a decoder with some "function outputs."

It takes an iron man to play with a toy iron horse.

Interesting that you are into KCS/BN since I live in Kansas City. Recently I had the opportunity with my job to be standing five feet away from a brand new KCS/BN loco as we were drilling in the yard. Too bad I didn't know enough at the time to really be able to communicate or appreciate the details of the engine as it passed.

Ditto! I have two dummy locos I did this to. One is a Proto 2000 and the other is an Athearn. On the Proto 2000 I already had a powered chassis that was badly damaged due to having been dropped. A friend sent me a a dummy Proto 2000 of the same model and I transplanted all the parts from the damaged frame to the good one. On the Athearn I used parts from my junk box to rebuild it into a powered unit. About twenty of my forty-two locos are Athearn's and I like them all. I'm in the process of converting them all to DCC.

Athearn powered and dummy locomotives use the same parts, so you could order the parts from Athearn.  This would be a rather expensive upgrade.  You might look for a used unit on Ebay or a swap meet and pull the "guts" out of it to install in your dummy locomotive.

For my layout I am building a fleet of KCS/BN SD-40 units to run unit coal trains.  Athearn units are great pullers, so part of my fleet includes multiple unit lash ups with powewed and dummy locomotives as I do not need the power to pull the train.

Here's the skinny: I bought a dummy Athearn SD-40 and didn't realize it was a dummy, because I am a dummy. I am interested in converting this to a working locomotive. Is it as easy as buying a motor kit and new power trucks and doing the install? Are light kits for passenger cars the same one that lights a locomotive?

Thanks for suggestions! You can even make fun of me for assuming that I bought a functional locomotive if you want.

Thanks!
