Hello I just returned from a trip out to Calif from Chicago taking the southwest cheif out and zephyr back. I quit smoking one week prior to leaving on my trip. I am so glad I quit as I noticed they do not give many breaks on the cheif and I am not sure If I would have enjoyed my trip. On the Z there seemed to be more breaks . I was very upset when they changed their smoking policy after I bought my tickets as it seems as though Amtrak is hard pressed to get my business and from others due to the cleanliness and lack of repair these trains are in. One of our porters told us Amtrak can not even afford a screw driver aboard to fix anything. I believed him after our experiences aboard. Good luck with the smoking. I am glad I quit.
