Welcome to the "Forum"! I am glad you found us, this is a great place to stay up with NG current events. Another interesting site, albeit crass at times, is "The Goat". Check your guns and knives at the door.
Your photography is very commendable. Railroad employees often have photo opportunities that really display the flavor of their operation with "behind the scenes" shots and from vantage points not usually accessible to the average railfan, including lots of shots that show the lay of the land, yard trackage, shops, etc. Thanks for a great example of this, one of the best virtual tours on the web.
