Artist Walter J. Wedlock began sketching vintage train stations in the 1970s to preserve them in ink before a third of them were torn down.
The resulting collection of 52 drawings and one watercolor were eventually donated to the California State Railroad Museum.
Last year the museum unveiled 26 of the works in a special exhibition. The rest of the sketches are now on display at the museum, 125 I St. in Old Sacramento.
Included in Wedlock's Gift: California Railroad Depot Images In Ink Phase Two are depots in Menlo Park (completed in 1867), Placentia (1910) and two in Fullerton (1922 and 1930). The artwork will stay on display until March 4.
Museum entry is $9 for adults; $4 for youths ages 6-17; free for children 5 and younger.
