Thomas & Friends

I have been watching the DVD's (usually the best of, or one that highlights a character) with both of my boys, and I LOVE this series, I haven't seen any yet with Ringo Starr as the narrator, but I am sure those will be just as enjoyable when I do get the first season. Does any one know what size they are modeling the series at? As a Train enthusiast, they look 'O' gage to me, but not sure if they have a different system over there to determine train size. I would love to see them at some point run a contest to create a new character ya know a color, face, name type thing.

And for those of you that got the season 1 DVD, How many episodes and what kind of bonus features came with it? I know I would like to see the sets they work with in terms of size alone because they must be HUGE!
