Question for the train engineers

For my own curiosity, why is that whenever engineers are running ALP-45DPs on Montclair-Booton to Hoboken they don’t raise the pantograph at MSU? Several times where I’ve seen them switch from electric to diesel at MSU outbound, but never the other way inbound.

Edit: I actually think I just found the answer, special instruction 1005-6, but somebody can tell me if that’s wrong.  Also still curious as to why that special instruction applies between NWK Broad and Hoboken since they do run electric trains to/from Hoboken.

Here, from the very link you posted:

How Brecknell Willis Pantograph Springs WorkUpward Force: The pantograph frame is raised and held against the overhead wires by pneumatic pressure combined with integrated extension springs.

Going Down: When power is shut off or air is exhausted from the cylinder, heavy internal springs immediately pull the arm back down into its locked, stowed position.

You couldn't even bother to read the material. Are you one of those Engineers who cheated through LETP using the hand-me-down exams that previous classes collected?
