Considered the world’s largest of its kind, this paradise for train buffs is mesmerizing for all.  Massive yet minutely detailed model layouts allow thrilling close-ups of the historic Cabrillo South-western, San Diego and Arizona Eastern, and Pacific Desert lines, as well as the challenging Tehachapi Pass. Each has been set up by separate railroad clubs whose members volunteer to design, construct and operate their particular exhibit.

In the Toy Train Gallery, children are encouraged to try their hand on the throttles that manoeuvre circa 1950s Lionel trains. Diehard rail enthusiasts show up on Tuesday and Friday evenings, when visitors are allowed to watch the various clubs fine-tune their exhibits.
