Sunday Train: Traveling to our deaths and the fatal Metro North derailment

Last Sunday Morning, the 5:45am from Poughkeepsie was running through the Bronx with 100-150 passengers aboard, when it sped through a 30mph speed limit curve at 82mph, derailed, over-turning four cars and killing four people.

This is a story with some differences in detail from the Spanish fatal derailment this summer, but one common feature: the lack of adequate Positive Train Control signaling on the corridor. In the Spanish case, project cost-shaving led to Positive Train Control signaling being installed on the new High Speed Rail corridor but not on connecting corridors that some hybrid services use to reach towns not directly on the HSR corridor. In the Spanish case, full PTC would not have been required to prevent the fatal accident: ‘The Santiago Train Derailment Could Have Been Prevented with a Euro 6,000 beacon’. As later details emerged it became clear that if two analog “ATSFA’ beacons had been replaced with three digital ‘ATSFA’ beacons, at a cost of €6,000 each, that would have prevented the fatal derailment.

The Metro-North connecting from Poughkeepsie through the Bronx into Manhattan is slated to receive Positive Train Control, as required by current Federal Railway Authority policy, but as recounted by Alan Levy:

Metro-North and the LIRR have been trying to wrangle their way out of the PTC mandate, saying it offers “marginal benefits”; a year and a half ago, the New York Post used the word “outrageous” to describe the PTC mandate, saying it would cost over a billion dollars and that the money could go to capacity improvements instead, such as station parking. Lobbying on behalf of Metro-North and the LIRR, Senator Charles Schumer emphasis mine made sure to amend a proposed Senate transportation bill to give the railroads waivers until 2018, so that they could devote resources to more rush hour capacity from the outer suburbs (such as Ronkonkoma) to Manhattan and fewer to safety. According to Siemens, the work will actually take until 2019, and Siemens says it “has developed PTC specifically for the North American market,” in other words built a bespoke system instead of ETCS. (ACSES was developed by Alstom.)

And that is the top-line point: if we had been more serious and committed about putting PTC on the busiest passenger rail corridors in the country, this fatal derailment would not have occurred.
