Fodor's Expert Review California State Railroad Museum

Sprawling over three floors, this museum celebrates the history of trains from their 19th-century English origins to the pre–jet age glory days of rail travel. A permanent exhibit details Chinese laborers' contributions to the transcontinental railroad's completion (Sacramento was the western terminus). Another section contains one of several gold spikes issued to commemorate the joining in Utah of the west-to-east Central Pacific and east-to-west Union Pacific lines.

Up to 21 of the museum's railroad cars and engines—among them Pullman-style cars and steam locomotives—are on exhibit, and there are interactive displays and a play area for kids. Two nearby affiliated attractions (both free) worth a peek if they're open are the re-creation of the circa-1876 Central Pacific passenger station (930 Front Street) and the Huntington, Hopkins & Company Hardware exhibit (113 I Street), a facsimile of a 19th-century hardware store.
