When Josh encounters Jenny on the train station platform, there is a train in the background in the long show when Jenny first turns and speaks. When the camera cuts to close up for her next line of the conversation, the train is gone.
In a previous episode, it was shown that the guard at the entrance to the community has access to several camera angles that were previously able to track where Jenny went across the neighbourhood.
Instead of easily finding out where Jenny had gone on her return to the neighbourhood in the morning, the police instead decide to go door-to-door in the community and ask the residents if they saw her which is a far slower and unreliable method.

The police don't order a house-to-house canvass of Jenny's neighbourhood until at least three days after she has been missing, even though it is obvious she may be endangered.
