At the beginning of the month, New York State released its draft environmental impact statement for high-speed rail from New York to the Upstate cities. The costs of HSR as proposed by the state are excessive, and as a result the state has eliminated the high-speed option. It is only considering medium-speed options – the fastest is 125 mph, for the cost of full-fat high-speed rail; it sandbagged the full-speed options. Consider the following passage, from the main document, section 3.2.2:
The dedicated right-of-way of the very high speed (VHS) alternatives would result in significant travel time savings (5:17 and 4:23 respectively for 160 mph MAS and 220 mph MAS), and commensurately higher estimated ridership (4.06 and 5.12 million respectively for 160 mph MAS and 220 mph MAS).
The length of New York-Buffalo is about 690 km. At 4:23, it is an average speed of 157 km/h. To put things in perspective, the Hikari express trains in the 1960s achieved an average of 162 km/h (515 km in 3:10) in 1965, with a maximum speed of 210 km/h.
In section 3.3.5, the 125 mph alternative, which involves greenfield dedicated track from Albany to Buffalo, is said to have an average speed of 77 mph, or 124 km/h. Considering that British express trains on the legacy East Coast and West Coast Main Lines restricted to the same top speed average about 130-140 km/h, this is unimpressive.
Likewise, the cost estimates seem too high. The cost proposed for 125 mph is $14.71 billion. That’s on existing track south of Albany with minor improvements; as per exhibits 3-19 and 3-21, 83% of the cost is said to be Albany-Buffalo, a distance of 380 km on new track plus 76 on existing track. This makes sense for a full-speed, 350 km/h line. But the cost of the full-speed 220 mph option is $39 billion, around $55 million per km from New York to Buffalo in an area with a topography that justifies at most half that.
The study also sandbags the higher-speed options, from 125 mph up, by overplaying the importance of skipped small cities. A greenfield line cannot reasonably serve Schenectady, Amsterdam, and Rome. It could serve Utica, but with some takings because the sharp curve from the tracks at the downtown station to the I-90 right-of-way to the west. Lack of service to Utica would be a drawback, but the study for some reason thinks that those four stations would need their own dedicated intercity line to New York, using a connection to Metro-North, which is said on PDF-p. 37 to have capacity problems on the Hudson Line (the Hudson Line runs 12 trains per hour at the peak today, and is four-tracked). I am told that people drive all the way from Watertown to Syracuse to take Amtrak; none of the skipped four stations is that far from Albany or Syracuse. If a regional train is needed, it can connect at Albany.
The problem is that the alignments studied are uninspiring. I don’t just mean it as a synonym for bad. I mean they avoid locations that look difficult at first glance but are actually reasonably easy. CSX bypasses Albany already; it is not a problem to run high-speed trains at low speed on the existing line between Rensselaer and a spot west of Albany where the line could transition to the Thruway, and yet exhibit 3-20 shows a passenger rail bypass of Albany.
For the full-speed option, I do not know how much tunneling and bridging the state thinks is necessary for its west-of-Hudson I-87 alignment from New York to Albany, but there’s an alignment east of the Hudson with only about 7 km of tunnel, all through the Hudson Highlands. Briefly, such a line would go east of the built-up area in Dutchess County and points north, with a possible station at the eastern edge of the Poughkeepsie urban area and another near Rhinebeck, closer to the city and to the bridge to Kingston than the present Rhinecliff station. In Putnam and northern Westchester Counties, it would utilize the fact that the ridge lines go northeast to southwest to swing to the southwest, to hook up to the Hudson Line slightly north of Croton-Harmon. With a curve radius of 4 km, and a maximum grade of 3.5%, only two tunnels are needed, one under Peekskill of about 2 km and one under the crest in Putnam County of about 5 km. Some additional viaducts are needed through the valleys in the Hudson Highlands, but from Dutchess County north the line would be almost entirely at-grade.
There is generally a tunnel vision in American high-speed rail documents like this, consisting of any of the following features:
- Excessive avoidance of greenfield alignments, even in relatively flat areas. The flip side is excessive usage of freeway rights-of-way. The Syracuse-Rochester segment is actually greenfield in the study, which is good, but there is no thought given to greenfield New York-Albany alignments, which are frankly much easier east of the Hudson than west of the Hudson.
- Questionable assumptions about the abilities of existing track in urban areas to have higher capacity, which often leads to excessive multi-tracking (as in California); there is never any effort to construct an integrated timetable to limit the construction of new tracks.
- No rail-on-rail grade separations. The study talks about Spuyten Duyvil capacity problems, which are very real if traffic grows, but says nothing about the possibility of grade-separating the junction from the Empire Connection to the Metro-North mainline to Grand Central.
- With the exception of California, which erred in the other direction, uninspiring speeds. It’s actually hard to construct a 350 km/h line that only averages 157; actual high-speed lines around the world in the 270+ range average about 180 or higher.
It’s not surprising New York is sandbagging HSR. A year and a half ago, the Cuomo administration killed an HSR study on the grounds that in a recession, the state can’t afford to build such an expensive project. Given how long it takes from the initial study to the beginning of construction, the argument is so transparently wrong that it raises the question of what the real motivation was. But whatever the real reason was, the state is not interested in HSR, and wrote a lengthy environmental impact study to justify its disinterest.
