Can I bring items in plastic bags on an amtrak train?

Other answer:

Yes, you can bring plastic bags containing items on an Amtrak train. Whatever you bring must not be unattended. Certain items (like firearms) are subject to special restrictions but carrying a plastic bag with things in it is not.

Amtrak does have the right to inspect your baggage; however I have never seen this done and I have often ridden on Amtrak trains.

Joe:
Yeah. As long as it doesn't take up too much room around your seat. Some items can't be taken on the train, so you can check this list to make sure everything you're bringing is allowed. Have a fun trip! http://www.amtrak.com/prohibited-items

It depends what they are – there are a few things which are banned on trains (but not many).
