The trestle in Wayne is a popular shortcut for youngsters going to and from nearby Willowbrook Mall.
NJ Transit spokeswoman Penny Bassett Hackett told The Star-Ledger of Newark Transportation Commissioner Jim Simpson and NJ Transit director James Weinstein will visit the site this week.
Police said three teens were walking across the trestle when a train headed for a repair station in Kearny came down the tracks at 60 mph on Sunday night.
One of the teens dove down an embankment and survived. The other two were killed.
Weinstein told the newspaper it's a mistake to assume a train is not coming down the tracks.
