The 3070 was a one-of-a-kind car ordered from Budd in 1936 at the same time car 3071, a similar smoothside lightweight car, was ordered from St. Louis Car Co. for evaluation. Budd won out and many subsequent light weight cars were ordered from them. It floated around the system on many of the lesser named trains until it was retired and sold to the NJ Transit. It lost its fender skirts over the wheels soon after delivery when testing some new air suspension trucks. They were never replaced but the rest of the skirting was still on when it was sold.
