A question has come up resulting from a topic in the Long Island forum: Did any railroad other than the Long Island, not counting Interurbans, use electric locomotives for switching industrial sidings? (There's an interesting thread just now on the Port Washington branch showing pre-WWII photos of industrial sidings with third rail--no doubt employees of those industries were well acquainted with the hazard.)
Believe both the PRR and the New Haven did switch online customers with electric power,most likely with "reacher" cars,if needed.
West 30th Street Branch of the NY Central was 3rd rail powered but used "Tri-Powered" locos switching customers,
till diesel switchers arrived.
