(If you ever watched the Muppets, you’d know about Pigs In Space.)
I was amused recently reading a Science Fiction novel, called “Night Train To Rigel”. To my recollection, it doesn’t have a Night train or go anywhere near Rigel - but it does have a train! The Quadrail System provides intergalactic travel at 1 light-year per minute, so a train ride between star systems can take a few days.
The train system described is acceptable, although the author admits that no-one knows what the 4th rail is for. The trains have engines, sidings, and all kinds of ‘normal’ features. The hero even gets out and climbs along the roof during an intergalactic trip - how that worked wasn’t explained. Anyway, a good fun thriller.
Apparently there are 3 more books in the Quadrail series. http://en.wikipedia.org/wiki/Quadrail_Series
