Alan,
I was totally unaware of this sad news. Jim's column, Jim Barrett in the Backshop, was a bible for me as I constructed my dream layout (still under construction). For example, I used his innovative method in Run 270 to create a hinged lift up section by modifying the hinges to avoid the rails of the tracks in the crease from impinging on each other (see photos of my layout). I had the pleasure of meeting Jim a few times at the TCA meets in York. A true gentleman.
The text is a great tribute to him and his contributions to our hobby. I just ordered the text. Perfect use of the $50 gift certificate my wife gave for Christmas for any train purchases! Also saves me time combing my back issues for the specific article I need.
Blessings to his family, especially during the holidays.
Michael
