A friend in the hobby pointed me to the February issue of Railfan & Railroad where the POVA is featured on the cover of the magazine! The article itself is very cool and very informative. I learned a lot I did not know about the railroad's history. I also finally got a good, clear sense of day-to-day operations on the modern POVA railroad. This helped to confirm that my freelanced approach to this railroad is indeed prototypical and should serve to re-create the feeling of modern shortline railroading in the pacific northwest nicely.
I must say, it is a bit overwhelming to have such a surge of information arrive on my doorstep after spending years and years trying to slowly piece together the puzzle that is this railroad from various blog postings, pictures, google maps, etc.
