The Lion Lines...San Franciso, CA

First I've ever heard of this.  Saw on eBay a listing for "The Lion Lines Lionel Green State Set, 4 Passenger Cars" which provided the following info:

The Lion Lines, Lionel Green State Reproduction Set, 4 Passenger Cars.

This set consists of:
Pullman Car California 412

Pullman Car Colorado 413
Pullman Car Illinois 414
Observation Car New York 416


State Cars Feature:
Exact reproduction from wheels to rooftop.
Hinged roof, dual interior lighting system, two lavatory and washroom compartments.
Weigh about 5 lbs each and are about 22 inches long.

Did they make an engine to go with this?  What other trains did they reproduce?
