CSXT Y12215, which is powered by CSXT 2644 and CSXT 6355, pull two separate Y122's into Acca. Three cabooses were in the consist, one at the beginning behind the engines, one separating the two trains in the middle, and one bringing up the rear. Y122 is an Acca to Clopton turn and uses the cabooses to make the reverse move from FA to Clopton and back.
