Ben,
The photo of the west side on Manhattan location is incorrect. The Composites never ran in service on the West Side as they were too heavy. They ran a few light trains around the horn to 155th St. Station on the last day of service on the 9th Ave el to run on the new Polo Grounds Shuttle. Those few cars were transfered at night The posted photo shown would have to be the 2nd or 3rd Ave. els.
regards , Nate
