A children's TV show that originally premiered on PBS from 1989-1993, with Thomas the Tank Engine stories coupled with segments involving real-life actors. It was actually a very funny and well-done show for its time. Both George Carlin and Ringo Starr were even separately featured on the show as well, each playing train conductors.
As of this entry, reruns of the show can now be seen on the Disney Channel.
Shining Time Station was one of the most unique shows in the 90's, combining model animation with real-life actors. (It's also the only way you can see a family-friendly George Carlin.)
