Amtrack and grey hound have a very strick no guns, period rules. that includes checked bags.
I was going to take the train north a few years back for a hunting trip. One of those deals where no "close" comm'l airports and the train with a cabin was cheaper then gas was for driving and it would take about the same time. Every thing was great until I asked about checked firearm procedure.
That is about to change for Amtrak.

Firearms in Checked Baggage
The Departments of Transportation and Housing and Urban Development, and Related Agencies Appropriations Act of 2010, enacted into law on December 16, 2009, requires Amtrak to implement the procedures necessary to provide storage and carriage of firearms in checked baggage cars and at Amtrak stations that accept checked baggage, within one year of the bill’s enactment. This requirement applies solely to checked baggage, not carry-on baggage.
Amtrak’s current policy prohibits all firearms, ammunition and other weapons aboard its trains. This includes any being carried on the person, in carry-on baggage or in checked baggage. Please be advised that this policy remains in effect until Amtrak begins firearms carriage in checked baggage on December 15, 2010; starting on this date all passengers wishing to check firearms or ammunition will be required to follow the Firearms Policy.
Firearms in Checked Baggage
Effective December 15, 2010, passengers will be allowed to check unloaded firearms and ammunition between Amtrak stations and on Amtrak trains that offer checked baggage service. The following policies apply:
Notification that the passenger will be checking firearms/ammunition must be made no later than 24 hours before train departure by calling Amtrak at 800-USA-RAIL. Online reservations for firearms/ammunition are not accepted.
All firearms and/or ammunition must be checked at least 30 minutes prior to train departure. Some larger stations require that baggage be checked earlier.
All firearms (rifles, shotguns, handguns, starter pistols) must be unloaded and in an approved, locked hard-sided container not exceeding 62" L x 17" W x 7" D (1575 mm x 432 mm x 178 mm). The passenger must have sole possession of the key or the combination for the lock to the container. The weight of the container may not exceed 50 lb/23 kg.
Smaller locked, hard-sided containers containing smaller unloaded firearms such as handguns and starter pistols must be securely stored within a suitcase or other item of checked baggage, but the existence of such a firearm must be declared.
All ammunition carried must be securely packed in the original manufacturer's container; in fiber, wood, or metal boxes; or in other packaging specifically designed to carry small amounts of ammunition. The maximum weight of all ammunition and containers may not exceed 11 lb/5 kg.
The passenger is responsible for knowing and following all federal, state, and local firearm laws at all jurisdictions to and through which he or she will be travelling.
All other Amtrak checked baggage policies apply, including limits on the number of pieces of checked baggage, the maximum weight of each piece (50 lb/23 kg).
Firearms/ammunition may not be carried in carry-on baggage; therefore, checked baggage must be available on all trains and at all stations in the passenger's itinerary.
At the time of check-in, passengers will be required to complete and sign a two-part Declaration Form.
BB guns and Compressed Air Guns (to include paintball markers), are to be treated as firearms and must comply with the above firearms policy. Canisters, tanks, or other devices containing propellants must be emptied prior to checking and securely packaged within the contents of the passenger's luggage.
Notice: Passengers failing to meet the above-mentioned requirements for checking firearms will be denied transportation.
