I've had almost any type of toy train: Brio [wooden trains], plastic [tyco, lego], ho and O gauge [lionel] trains. So I've grown up with them all my life.
Took a subway ride like at 6 yrs old with my grandpa all the way to Utica on the . I guess I really got into transit more when I took the subway to hs and of course went online more and chatted with other transit fans.
Although I do like transit, my interest has gone down and it's just a mild interest in it. I still try to keep up with the more significant stuff, but as for like what an R160A or B is from the distance - don't care, it's the same thing, boring.
