If you are looking for something a little different to do on the weekends.  Something you can take the kids to; then the Santa Susan Train Depot located on the east end of Simi Valley is open from 1:00 pm to 4:00 pm on Saturdays and Sundays.  The Santa Susana Historical Train Society maintains an HO scale model train layout depicting the 1950's Simi Valley Area.  Please visit the Depot's site for more information viewing the trains as I noticed their website has some conflicting information on when the model trains run.  http://www.ranchosimifoundation.com/

The original 1903 depot has been restored and houses the model train layout.  you can enjoy a piece of our Simi Valley history an enjoy a large model train layout maintianed by the Santa Susana Railroad Historical Society.
