The San Jose Steam Railroad Museum is a planned railroad museum within Santa Clara County has been under development by California Trolley and Railroad Corporation since 1992. This project was originally intended to be located at the Santa Clara County Fairgrounds in San Jose, California; however in 2002, the Board of Supervisors voted to rescind support of the proposed railroad museum at that location. Since that time, CTRC has been actively working with various public agencies for a suitable alternate site. The proposed location is near downtown San Jose.
The Lenzen Roundhouse consists of the six stall San Jose Roundhouse, eighty foot turntable, water tower and herder's shack. The roundhouse was donated to the CRTC by Southern Pacific Railroad. The roundhouse was disassembled and moved to the Santa Clara County Fairgrounds(37°18′02″N 121°51′25″W / 37.300690°N 121.856811°W)
for storage until a site is found for the museum.
