BART is officially over the hill, as the transit service turns 40 years young this month. And it wants your memories for its party.
BART riders are asked to cough up "old photographs and memorabilia of years past on the train," according to the San Francisco Appeal online newspaper.
"Throughout the next year, BART will be displaying vintage BART photographs -- such as BART agents posing in front of fare gates in orange, collared shirts and the flared pants of the 1970s," the newspaper reported. And maybe they'll show some of yours, too!
"Old system maps, tickets, advertisements... and more" are also on the docket. Just imagine what it was like to pack onto a crowded commuter-hour car -- but in the past!
BART service began on Sept. 11, 1972, the newspaper reported. The Transbay Tube began operation in September 1974 -- and trains began running on Sundays in 1978.
BART historians are asked to contribute ephemera from a former era to BART's official Pinterest account, at www.pinterest.com/sfbart/celebrating-40-years-of-service. You can also tag photos on Flickr with "Barth40th."
