I'm a railroad fan residing in the Midwest United States.  Railroad traffic control and signaling are my special interests and I know a lot about them. 

I don't have a favorite era or railroad or route, but I do like old and new.  My favorite spot to railfan is Crawford, Nebraska and points towards and including Alliance.

If you have a question on a topic I might know about, feel free to ask.  I will help if I can.  You can also ask about additional contact and messaging options.
