LIRR C-Liner #2004, Train #4012 as depicted on John Scala's LIRR book cover: 'Diesels of the Sunrise Trail'
The author's caption: "Railfan Norman Kohl captures train 4012, with doubleheaded C-Liners (second unit in tow as they did not multiple) just west of Bethpage on 10/13/63."
As the second unit, in tow, couldn't be MU'd and no need for multiple crews in diesel lash up consists, the misnomer of 'doubleheaded' as applied to steam lingers here. I turn this back over to the OP.
