nicely weathered vintage american industrial outdoor "yard limit" railroad sign salvaged from an old chicago trainyard. the exact sign fabricator is not known. the sign is comprised of die cut steel with bold black lettering left largely intact. contains two holes for mounting against a signpost. rail yards typically have a complex series of railroad tracks for storing, sorting, or loading/unloading railroad cars and/or locomotives. railroad yards have many tracks in parallel for keeping rolling stock stored off the mainline, so that they do not obstruct the flow of traffic. railroad cars are moved around by specially designed yard switchers (i.e., locomotive). railroad yards are normally built where there is a need to store cars while they are not being loaded or unloaded, or are waiting to be assembled into trains. towers are used to oversee and/or control operations within the yard limits. measures 16 x 12 inches.
