What is your most popular train with non train loving visitors?

Originally billed as "The Most Beautiful Train in The World", the Southern Pacific Daylight, attracts more comments from EVERYBODY, whether "train folks" or not. 

Thus, my 12 car Golden Gate Depot, scale, Daylight passenger set (including articulated diner and chair cars), hauled by either a black GS-4 or a red, orange & black GS-4, is the obvious choice!

Matt is correct when it comes to the children, they love the Metro link because it is familiare to them, however the adults who ride it have other feeling for the Metrolink.

$$#%$^& train

My MTH Yellowstone pulling 67 cars draws the biggest reaction form non-train people.
