The "Dream" would be to use 2 slots in the overnight on the NEC thru NY Penn,1 EB and 1 WB slot to move the
Roadrailers to/from the island,all Haz-Mat loads will have go the long way around(a given),hand off to NY+A at Harold,
then get the roadrailers to where the yard is to be delivered by road to destination. Loads and empties would be gathered
the sent west,handed off at Harold then delivered to a nearby NS yard.(a "happy" retirement home for a few HHP-8's)
It would depend on Amtrak giving up(allowing) the 2 slots.
Now the reality,NJNY is still in rebuilding mode on the NJ side(Greeville),Only CSX(CP by "tradeoff" of routes) and P+W
stone trains service the island with interchange to the NY+A at Fresh Pond, the unloved long detour via Selkirk,
and long haul truck drivers not wanting to deliver on the Island(Lack of outbound freight,the biggest reason,
then tack on traffic cogestion,and going thru NYC in/out,etc...)
NY+A is "hamstrung" by LIRR's indefference to freight in general.
The Land of Enchantment is not Flyover country!
