Not really. You said correctly above. Grade separated terminals are almost mandatory at this point, particularly if you're planning to raise speeds. AS it is, you're at the fringes of 135mph territory and everything must come to a stop if a train needs to head east from County Yard.

Granted, there are plans to raise the diverging speeds through County, but you're still talking about stopping all traffic.

Eliminating JErsey Ave as a terminal is the only other solution because even if you decided to run east on 4, the train would still have to cross over somewhere.
Oh, I was just suggesting that perhaps some less land-intensive solution (a relay track(s) with a flyunder?) maybe feasible/easier to do. As you say, the current setup is completely unsustainable, and has all sorts of knock-on impacts for scheduling, reliability, etc.

It'd shorten it for sure, but much of the capacity loss would still remain. You still have to hold out all traffic, give the lineup, get the train across, reline, and then give the proceed. Even the best flat junctions in Europe are very much targets for elimination where possible -- those sorts of delays are not acceptable if you're trying to schedule and run a precise, high capacity railroad.
