I thought that too, but I think it's an optical illusion. There is another set of harrimans on an adjacent track, that look like that last three cars of the first train. Train 128 ran with 6 harrimans from the 1960s until about 1975-76 when it was dropped to 5 harrimans. The longest string of harrimans I recall seeing, was 8, and that was only on certain holiday times when they added a couple to 122 (4:15pm departure) for people getting off work early. Of course, in the pre-late 1960s days there were longer strings of harrimans.
