#16 - An eastbound 4000-series train is on Van Buren Street at Paulina. The 4000s represented the middle years of the street level operation, bridging wood cars (early) and 6000s (later). The new structure for Douglas trains is behind the facing train. Paulina's streetcar tracks are no longer evident. Answer: CTA 4446 at Van Buren/Paulina on April 21, 1957. (Photo by Ray DeGroote)
