I just found it! This version has 100 questions actually asked on the Auto Train. Obviously, some are more amusing than others, so I won't repeat the whole list:
1. Which way is the train going? (asked at nighttime; answer: "North", which leaves the person equally perplexed).
2. Is the lemonade real? (No, it's imaginary)
27. Do you live here (asked anywhere enroute)
38. Have you seen my wife? (probably)
41. Do you eat the same food we eat? (No, the crew has its own private dining car)
44. Where's the free snacks? (we used to have them in the lounge car)
48. Do you get asked a lot of questions? (I'll let you guess)
49. Is this the diner? (usually asked in the diner, but sometimes in the lounge)
50. Are we here? (Yes, we're not someplace else)
51. Is the fish tough?
55. Is [name of employee from the distant past] still on the train?
56. Will the cars come up on the other train? (What other train? The autos are in the carriers at the rear of this train)
71. What's that smell? Do something about it. (asked while passing a paper mill)
75. Can I have a cigarette here? (asked in the vestibule)
83. What's the weather like in Virginia (or Florida)?
88. Aren't you hot? (asked in Sanford, FL in July, when the temperature is often 100 deg. on the platform during mid-afternoon boarding. Answer, "Uhhhh, yeah.")
89. Do you like your job?
93. Can we have two desserts?
94. Can we have seats facing forward?
98. Are you the nurse? (A real question asked of a chef who was wearing his white jacket)
Unnumbered addition. Do we go through any tunnels? (The train hugs the coast, traversing generally flat terrain for the entire trip, but we were not above resorting to fiction. Once we told somebody about the Great Okeechobee Mountain Range with its many long tunnels, and high bridges spanning spectacular gorges. Then we relented and told them the more mundane truth)
