I picked up a BC75XLT a couple of years ago. This scanner has 10 preprogrammed banks in it, of interest to you would be the railroad bank (Along with weather, police, fire, marine, racing frequencies, air, ham AKA amateur radio, CB and one listed as "Other" that covers FRS, GMRS and MURS frequencies).
I've taken mine on trackside forays as well as while riding Amtrak and MARC trains and it performs well. I would suggest a different antenna to replace the supplied "rubber duck" and will advise you that battery life is somewhat limited (It only uses two "AA" batteries) so I generally get approximately 5 to 6 hours of use.
Here's a some information from RadioReference on the scanner:
A link to "Bearcat Warehouse" where the BC75XLT is selling for $80. (I've no connection to Bearcat Warehouse except as a satisfied customer.)
