Recently, I was chatting about heritage trains with two different people, both on different occasions. I was really surprised to learn that both of them did not know the difference between a steam engine and a diesel! 
One person readily admitted that she couldn't tell the difference. And I could soon tell that the other person (a different occasion a few weeks later) also didn't understand the difference between the two. I kept a straight face and didn't say too much, but inside I couldn't believe it! I've been schooled on the basic differences between these two types of loco since I was 4 or 5. To me, it couldn't be more obvious ... And my four-year-old son has no problems separating the steamers from the diesels!
So, I'm guessing that there is a significant chunk of the population who can't tell a steam train from a diesel. I realize I'm jumping to conclusions here but I bet I'm right. Has any one else come across this?
Just curious
