Much less common than the ubiquitous E-44's on the Northeast Corridor were the E-33's. These units were originally built for the Virginian Railroad but were rendered surplus when the N&W acquired the Virginian and de-activated the electrification, whereupon they were acquired by the New Haven Railroad to replace some of their very aged freight units. After serving as the New Haven's mainstay electric freight power for many years, they were conveyed to Penn Central when the New Haven was acquired as a condition of the NYC/Pennsylvania merger.
Here a pair of the motors are hurrying a freight south through Elizabeth, NJ. Some of these units lasted into the Conrail era.
Besides the locomotives I also happen to like the period billboards in the background
