Can anyone remember a sci-fi series on TV where a train stops in a tunnel and everyone falls asleep for around 15 years, to find a corrupt leader who conducted some experiment originally.

Sounds like: The Last Train (TV series) (http://en.wikipedia.org/wiki/The_Last_Train_%28TV_series%29) but that was from 1999

Awesome! I checked a clip on it and it is the one I was looking for. Thanks a bundle!!
