There is a new set of crossovers at US 46 overpass. One set directly underneath the overpass switches from track 1 sb to track 2, while another set about 0.1mi south switches from track 2 to 1 sb.

There is also a new switch which connects the riverline sb to NYS&W. This switch is at MP6.0 exactly.

All of the crossovers and the NYSW switch are controlled by the CP5 interlocking.
The SB signal gantry for CP5 is at the US46 bridge, and the NB gantry is south of Bergen Turnpike where it has always been.

I was down there on Thanksgiving day. There were two NYSW diesels idling at the water tower (1804 and 2012). I did not catch any activity on CSX while I was there. Seemed to be a quiet day.

Still plenty of activity on the Riverline. But there are of course huge gaps during the day.

I'm looking for detailed maps for area from CP5 south to Newark. Using MapQuest Aerial maps for now, but not good detail.

As you probably know, the Riverline no longer goes through the tunnel from NB into Weehawken. NJT light-rail uses that tunnel now.
Riverline follows what I believe was originally the EL into Croxton, then south to Marion jct where SB trains can go west into OI (Newark) yard using the new track and switches installed several years ago (probably more like 10 years now!).
Remember when they used to have to do a reverse move at Marion because there was no SB to WB access?

I got a glimpse of that construction from a NJT train out of Hoboken I was on. That was a while ago...
