Over the chequered history of TV sketch shows, it's hard to think of many with better credentials than this series.
Spawned by the warped minds of Father Ted writers Graham Linehan and Arthur Matthews, its cast have gone on to dominate the 'A' list of top comic actors in Britain.
What would a new comedy now give for a line-up featuring Simon Pegg, Mark Heap, Kevin Eldon, Rebecca Front, Julia Davis and Catherine Tate?
Big Train is probably already little more than a footnote in their individual careers, but that's a shame because together they created one of the freshest and most underrated sketch shows of recent years.
A smattering of returning items peppered the first series (directed by Linehan), including weekly animation 'World Championship Staring', with commentary by BBC legend Barry Davies.
But recurring segments weren't the focus, each show instead remaining consistently unpredictable and juggling a rapid pace with sudden leaps in tone.
It was four years before a second series reached our screens, this time with just Matthews at the helm, but the star performers were back and with them the show's zany mix of the macabre and the surreal (finally answering for us big burning questions like what Ming the Merciless does in his spare time).
Big Train stood out not only for its variety, but also for the obvious chemistry between the cast and the notably high production values; deciding to shoot on film gave their movie parodies added punch, whether they were spoofing Hitchcock, Hollywood or French film.
Sandwiched in time between juggernauts The Fast Show and Little Britain, the same fan-base might not have boarded Big Train.
Nevertheless, in steering away from catchphrase comedy and offering plenty of fresh gags each week, it was reliably both funny and original.
