Recently, my wife bought a serving tray ready for Christmas. I didn't realise that she was a Model Railroad fan!

Rick (rtw3d) had made a suggestion about filtering and being able to filter out certain users or subjects. 
It reminded me of something that I've often wished was possible.  Who knows, maybe it is.  I'll use myself as an example:

Hey, everybody! I recently hooked up a SoundCar decoder to an external speaker and it sounds amazing. I'm going the do the same with a diesel decoder although I haven't purchased one yet. I'm kind of waiting for the TCS WOW Diesel before making a decision between Tsunami, TCS, or Lok. It'll be for a EMD 645 non turbo. I remember reading a work around for coasting with a Tsunami but I'm hoping newer decoders can eliminate extra programming.

First let me state that I am not Union Pacific modeler,  I model the Spokane Portland & Seattle 5th subdivision in 1968 which crossed the UP mainline at the Celilo Bridge and connects at OT Junction. I am a long way off from modeling this area, but in doing some research about the area I came across an image of the Portland Rose cruising along the south bank of the Columbia River. What peaked my interest was the fact the train was a very short prototype train that would be great sa a Pike Size passenger train.
