Here is another piece of information that has been lost in the morass of conflicting stories about PTC. From an opinion article at CNN by Fred Frailey (long time Trains Magazine writer and columnist):

Meanwhile, Amtrak has its own version of positive train control, called Advanced Civil Speed Enforcement System. Its sophisticated technology is tested and known to work. Alas, its adoption has been slow in the Amtrak-owned Northeast Corridor, operative only between Boston and New Haven, Connecticut, on a short stretch of New Jersey just outside of New York City and in parts of northern Maryland.
The danger train travel can't banish

The irony is that this technology was installed and operating for southbound trains at this location because of the dramatic speed reduction from 110 mph to 70 mph or lower. It was not installed northbound because the speed reduction required to safely take the curve was not considered significant enough to warrant it's installation. Based on what I have read elsewhere, to install that technology would only require a few days labor for hardware work and very little software programming.

In summary, the PTC commotion regarding this specific location is mainly BS and I would expect that the current system will be in and working at that location well before the end of the year. As for PTC, Boardman or no one else can guarantee it will be working flawlessly by the start of 2016. As Frailey states:

Not until 2017 or 2018 will the large railroads finish installing positive train control. And until they do and flip the switch, there's no guarantee that it will even work. One fear is that positive train control will choke on its own complexity and slow the railroad network to a crawl.
