Steam Acs-64 Getting Routed Over Third Rail Sections

Hi,

I was playing on NY to Trenton. Specifically, the 97 Sunnyside Yard - NY Penn Station with the ACS-64 at 2:41 PM - I got routed through a section of track which is only third-rail electrified Is this intentional?

 

I saw the same thing on a service earlier in the day.

I can run in the section without an overhead wire. I was the night, but, as for this weird vehicle, is a supplier special?
