railroad frequencies specifically for baltimore, maryland.

Best national lists I know of:

N8OAY's list:

Scroll sideways over to Maryland.

There are other lists, but they get out of date.

Amtrak NE Corridor:

best Yahoo! group for this info:
http://finance.groups.yahoo.com/group/RailScan/

This group attracts railfans with amateur licenses.

I haven't been to Baltimore in over ten years, though it's not that far away.

Bonus: Maryland Midland frequencies:
AAR channel 21 160.425 Maryland Midland
AAR channel 29 160.545 Maryland Midland
