Does anyone know the title of a 1970s era (could be early 80's) fictional movie that is set in the time of post apocalyptic USA and centers around a surviving community dominated by women, with men as slaves. They use a transit system of super fast underground trains or capsules that was contructed before whatever holocaust occurred. A man from the past who built the transit system is somehow awakened in the future world and the movie surrounds his experiences in this new civilization. This main character was a popular B movie actor of the time and was in similar type flicks of that era.

Anyone know the title or the actor's name ?
