I used to commute through Hoboken three days a week. So I was aware that heavy rains and high tides sometimes produced some flooding but this is the first I heard that the terminal floods on a regular basis.

If it rains heavy, the terminal will flood at high tide. Also, if it rains heavy up north on the Hudson River, the terminal will flood under the same conditions.

Shouldn't they have been able to have arranged the plugs to dangle from above, and be relatively easily moved closer to the ceiling, or modularly detached and replaced? I'm assuming train hotel power is 600 volts DC.

The smart move would've been to put what I believe are the red boxes on the ground in the yard, elevated off the ground in panels similar to this: http://bit.ly/vzAnPZ

I know this is a stupid idea, but if this does turn into a serious problem in Hoboken, the easiest solution is to just shut the diesel down and hook up an electric to keep trains energized instead of installing the HEP boxes and associated cables, right? Its hyperthetical of course. Of course soemtimes you have to worry, once you shut a diesel down, you hope that it comes back online....Patrick Boylan wrote: Shouldn't they have been able to have arranged the plugs to dangle from above, and be relatively easily moved closer to the ceiling, or modularly detached and replaced?

AFAIK, train HEP is transmitted via 480VAC bus on Amtrak and NJT trains/coaches. From there, I would think the voltage is then stepped down on board each car for the various systems.
Patrick Boylan wrote:No, the hotel power is 480 volts, three-phase A.C. You probably got the 600 volt D.C. idea from the LIRRs push-pull cars, which had that type of hotel power. But the LIRR cars were former electric MU cars which were modified for diesel territory operation when they were displaced from electric schedules by the then-new M-1 cars. They needed a source of 600 volt D.C. in lieu of third rail current to drive the air conditioning, lighting and electric heat in the cars. The NJT cars do not fall into this category.sullivan1985 wrote:There are wayside plugs on some depot tracks.

Thanks for coming in today!
