We came from living in another country and it was fantastic for our pets travelling. They have the regular trains (pretty similar to the Amtraks in design for the newer ones) and actually they were really pet friendly. To be honest, everywhere was pet friendly (stores, restaurants, travel, etc) and my chi was raised going on trips or waiting at the trains for my husband to get back from work some days with me. They not only allowed it but she always got lots of positive attention for years. We've been back her now over a year-the plane flight was fine but we can't find many places that are pet friendly (though we live on bringfido.com). We don't go out much other then the dog parks and downtown but look for special events that can be happening for pet owners. Recently we had to go to over 10 hotels when our ac broke just to find one that would accept them (a 2 lb and 5 lb chihuahua for crying out loud). When we found one we paid an extra $200 in pet fees and deposits for the two nights it took to fix the ac. Really had so much fun on the trains with Lolli and the family going places-it would be awesome if Amtrak offered excursions allowing small pets. We had to have a passport and chip for her in Europe to go on the trains but they were really very easy and nice giving her permission-never even needed an extra ticket with our yearly ones after asking. Very disappointed now that we can't do those things anymore here (this is Fl-could be better in other states for the pet allowances). I really understand-she is our baby too. If we have to go anywhere away for some hours, she stays with our pet sitter.
