David is correct... A command station is that and will not be replaced by a computer running JMRI.
I have left two of the (Steve's) RPi-JMRI boxes at friends for their (1) Digitrax RR and (2) NCE RR... Simple and straight forward they just work, we run trains with WiFi throttles.
If you wanted a programming computer it will do that too, need human I/O but that can even be a PC or Laptop that can run a VCN into the Pi so it doesn't need keyboard, mouse and screen.
I look at the Pi and marvel... okay 40 years ago my first computer was 1/1000 the horse power at 500 times the price... didn't even do WiFi...
Part of the advantage of the Pi if used for the WiFi to Digitrax is that it able to be turned on and off like any other appliance not needing an orderly shut down and hoping that in the case of Windows waiting for the big update to finish... Another part of that advantage is that as it's configured to provide it own set of IP addresses and passwords it completely off the home network and you're not giving out passwords you might not want to.
