I am a model railroader, also although I haven't touched the trains since I got back into R/C in 2005. Parts of my layout are finished, others are still in the roughed in stages. My trains all have decoders (receivers) in them and are run by what is called Digital Command Control or DCC. The signal is not sent through radio waves but is sent down the rails. I can control up to 3 trains at the same time. Each loco has a specific identity code that must be brought to the screen on the controller to control that loco.

The model trains hobby is even worse off then R/C, as far as kits being replaced by ready to run stuff! This is really stupid as a typical kit only took about 15 minutes to build. These kits, for the most part have been replaced by expensive RTR equipment.

There are some fantastic model railroad layouts! The hobby has as much depth and is as interesting as R/C in every way!
