Hello fellow railfans. My name is Calvin B. and I live in Baltimore, MD. I figured since this part of Maryland is pretty much CSX territory, this would be an ideal site to ask this question. I wanted to know where can I find a radio scanner so I'll be able to know when a freight train is approaching a particular section. It seems like whenever I'm not around the tracks, that's when I miss the most action. I'll like to be able to pinpoint rail action on the CSX Philadelphia subdivision along Rt-40 which becomes the Baltimore Subdivision once it passes Bayview Yard. I also live very close to the CSX line that runs along Wabash Avenue underneath the Metro from West Cold Spring to Reistertown Plaza. Any assistance you can offer will be greatly appreciated.
