Any one know if Amtrak has closed one of the North river bores for extended work during this cut back of trains serving NYP. That would depend on NJT having cut back enough ?

If they can single track (6 trains an hour!) and have NJT go heavy Hoboken, that may work. But I think you may have some passengers going to Boston from DC (and reverse). I doubt you can shut the tunnels completely down.
Given that Acela is off and the schedule is so limited, what's to keep from diverting all NYP trains from Washington into Hoboken for a few weeks and doing tunnel work? Maybe truncate the Silvers at Washington as well or just run the coaches up north, while the sleepers/diners are serviced at Washington. The real question is, could a heavily cut back NJT and Amtrak be housed at Hoboken for four weeks?

If you stack things so 30 minutes are northbound, 30 minutes southbound, capacity is more like 10-12 per hour if done right. And that's DEFINITELY more than enough.From earlier in this thread...

I can believe that figure of 24 down to 6. Assume 24 one-ways in two tubes. That's 12 in one tube one way no switching... or a train every 5 minutes. The distance between interlocks (BERGEN to A) is 3.4 miles (per Wikimapia measurement). The trains have to clear that entire stretch before switching directions... which takes time.
Anyone know what the speed limit is in this stretch?

12 in one direction in an hour, 6 in a half hour... take out two slots for clearance, track switching... and the trains are going to be idle once the signal hits proceed...
Yeah, 6/hour both directions in one tube is likely the max. 9 is assuming a lot about switching and train speed, which physics doesn't really bear out.

Ideally you would have workers self isolate for 2 weeks before starting , that gives you time to work out social distancing rules / techniques, then have them isolate / restricts contacts whilst the work is in progress. Reimburse them accordingly. Would there be enough personnel available?From within the construction industry, it depends on the project. Construction hasn’t been formally designated “an essential industry” as a whole by the Federal government, but to my knowledge every state government has been treating the entire industry as such - that’s at least the case in DC, Maryland and Virginia and in New York. Everyone has been getting PPE (masks, rubber gloves) and at least limited training on do/don’t with COVID-19, and some job sites have been doing temporal separation (one subcontractor works mornings, another evenings, and one third shift/overnight.) I’m also personally aware of a job that had part of its site closed and decontaminated when a worker reported to the hospital and tested positive for COVID.

It is too bad MOW forces were already involved in long term projects that had already started. This would be the perfect time to undercut or change the rail and/or ties on the High Line.
