Even if a family has another kid on the way, they still need to make sure they have budgeted properly before building an expansion on the house.
There are millions of children in New Jersey that need their parents to be employed. Counter-cyclical spending helps to accomplish that, and if done wisely, it also acts as an investment from which those children will reap the benefits.
Discourse about government spending these days is sadly devoid of numbers that indicate the right choice one way or the other. We don't run our businesses this way.
Maybe, but that's not how "the great stimulus" money was spent. (And, as Obama learned, there are no shovel-ready projects.)
At this point, your argument is basically "yes, we pissed away the last $1-2T, but this time, we'll get it right."
Assuming that the activity you're financing will return future positive captureable value (farebox revenues, increased taxable business activity), then borrowing money now to pay for current activities ensuring ability to pay back the loan makes perfect sense.
Note that that assumption of future benefit may not hold out, but if it does, failing to undertake the financing is cutting off your nose to spite your face.

Also interesting: "The Regional Plan Association, which held the conference at which Lhota spoke, and other advocacy groups have expressed support for through-running—at least until Gateway Tunnel gets built."
I.e., they want to be more efficient, but only as a stopgap measure until the tunnel is built.

So while this might get us a few percent increase in the number of trains for now, at the cost of a few hundred million to build out third rails in NJ (or catenaries in LIRR areas where NJ transit trains might be routed), it doesn't change the fundamental infrastructure issue given the growth of mass transit in the NYC metro area.
