Throwback Saturday! The CTA announced it will celebrate the 50th anniversary of the Yellow Line on Saturday with rides on two train cars from the 1920s.

The event will be held at 11 a.m. at the Oakton-Skokie stop, 4800 Oakton St. For $2.25, attendees can ride 4000-series train cars built in 1923 and nicknamed the "plushies" because of their green plush seats, the CTA said.

The cars also feature wooden roofs, interior mahogany trim, electric fans, lights with glass lampshades and porcelain handholds for riders who stand.

The Yellow Line, also known as the Skokie Swift, opened on April 20, 1964 with service from Dempster to Howard, the CTA said.

Last year, the Yellow Line had more than 1.9 million total station entries. The Oakton-Skokie station, the second stop on the Yellow Line, opened two years ago.
