Looking for a diner

[sbude]

Maybe some of you Hoosiers could help me. I'm trying to locate a Diner I saw while riding the train. It's located somewhere in Northeast Indiana along the Amtrak route. All I can recall is that it was near the Ohio border. It's an old streamline passenger car that has been converted to a restaurant. I just saw it in passing and didn't get the name. Been trying to find it for a couple of years now, but can't even remember the name of the town it was in.
