Sunil:

I would have a Real Estate Attorney look into the ownership of the abandoned railroad line. Around here (don't know about anywhere else) railroads' deeds for their roadbeds are only good while they are used - the ownership is supposed to revert back to the original owner if the railroad abandoned the roadbed (this clause has been frequently ignored here as railroads have "donated" property they no longer own for use as public bicycle paths, usually to the chagrin of the surrounding property owners). If this is the case with your CSX line (and you can prove it), you should be able to recover the roadbed property and be able to block it off to prevent vehicular access.
