Just because something's "documented" doesn't make it factual.You're right, your posts here are a form of documentation and they're clearly not factual. Look at HBLRT and its costs reaching into the billions right now—those costs would never have been accumulated if that line was built as a Hoboken-Bayonne commuter rail service, even an electrified one. Yes HBLRT is quite overbuilt and thus quite expensive. It certain has some bells and whistles which a North Shore LRT system would not require. The catenary, if equipped with larger insulators probably would work with the NJCL between Long Branch and Bay Head, and a far less complicated arrangement would work equally well. The cab signalling system could possibly be deleted, even though that'd potentially eliminate the possibility of running expresses on the opposite direction track. Still with all the work done in Jersey City and into Hoboken HBLRT really isn't a fair comparison to the simpler construction for a North Shore LRT. The Snug Harbor alignment could be problematic what with the problems with geotechnical analysis. While the LRT/DMU places the tracks inland of a bike trail over the bulkhead the heavy rail plan would place the tracks on the north side of the bike path, thus placing them over the current edge of water. This creates a greater load on the unpredictable littoral soil and increases the uncertainty with which the engineers can assess the loading characteristics of that soil. Such uncertainty leads to greater construction costs, since they either have to prepare for very great soil consolidation or face the prospect that after 5 or more years the line will have sunk up to a foot. look at the Trenton-Camden "River Line". What is there to look at? You think your electrified commuter line would come in for less than 17 million dollars a mile? Hell it's a few million shy of 20% the cost per mile of HBLRT. If you're looking for some shred of evidence of economic malfeasance on the part of NJT's light rail construction you're barking up the wrong tree. It may not be the most politically sound project, but it's hardly been a waste of money. |
