On any given Amtrak sector, there are potential travelers who could use safe and cost-effective transportation for their pets. Certainly potentially dangerous pets like spiders and reptiles should likely not be accepted for carriage. However, dogs, cats, rabbits, ferrets and other small mammals could very easily ride in a baggage car during reasonable weather conditions.
A basic surcharge could be applied for the cages/kennels and it has the potential create revenue and to draw attention to Amtrak.
A terms of carriage memo could be created to ensure that everyone knows the drill and the pet is comfortable enroute..
Pet owners are very concerned about safety and more than likely will follow the rules presented by Amtrak.
To solve space issues, Amtrak could assign certain areas in the baggage car to pet carriage, just like the new bike carriers on
the Viewliner cars.
If my memory serves, some Superliner cars have adequate climate-controlled baggage space below deck, just right for pets.
Apart from vacation travel with owners, there are other circumstances where animals need to be transported carefully and with minimal exposure to altitude and the elements. In America, there are pet shows where all types of the mammals mentioned before, and their owners need transportation.
Safe and cost-effective pet carriage domestically, is a wide-open market. If Amtrak uses their resources properly, they could gain some business, make some friends and help many people at the same time.
