Probably the set I want least from the series.
I'd like it to have a couple more cars, so I'll wait and see if they have extra cars as an add-on and if not I'll have to buy an extra set I guess.
Maybe the extra engine could be used at a train station decoration or such, for kids to play in?
Nice idea. That made me also think of a neighborhood park climbing toy perhaps or a grocery store 50 cent ride.
