Notice in this report that the signal that halted rush out traffic
throughout Brooklyn and Queens was a NEW switch that had ZERO capcity
for human intervention. And the MTA is promising us, in the
investigation, to spend billions more this come year to make more of
these... as a solution..

Bergen StreetSignal InvestigationLearning from Recent Failures and
Planning for the FutureOverviewOn March 15, the signal system at Bergen
St failed, causing service disruptions and major delays on F, G, A, C,
D, E, and M lines. One train was stuck in between stations for over an
hour, and hundreds of trains were delayed. We know you expect more from
us, and weve takenaction to identify the root causes and remedy while
continuing to provide 24/7 service. The following report details our
findings to date and the work weve doneto stop these types of
disruptions from happening again.Our investigation and repair-work
continuein partnership with the manufacturer of the signal system,
incorporating learnings from theadditionalsignal failuresover the past
month.Bergen St SignalThe interlocking signal system at Bergen St is
relatively new, having been installed in 2006. The manufacturer, Thales,
designed it with certain redundancies so that if one element fails,
another can fulfill its task, and service wont suffer.It was
specifically designed to not allow trains to enter a dangerous situation
and has fail-proof settings to prevent unsafe conditions. When failures
are detected by the system, we cannot force the system, which keeps New
Yorkers safe but can cause significant delays, to behave differently.Key
findingsThis was not a result of one issue, but of multiple factors: The
system threw off multiple FEC (Field Element Controllers) and
I/M(Interlocking Module)failures, whichmade redundancies
ineffective.Theelectronic components of thesignal system did not have a
consistent Uninterruptible Power Supply (UPS), which would prevent dips
and surges that might have caused several of the FEC and I/M
failures.The Bergen St Station is not accessible by other subway lines,
and because this occurred during rush hour, our specialists coming from
various boroughs had difficulty reaching the station. What were doing
differentlyWe have specialized staff on-siteat Bergen St24/7 to survey
performanceof the signal systemand troubleshootin real-time should the
need arise.Ourengineers have made modifications to the circuitry to
stabilize and monitor the power draw andareworking to reinstate the
Uninterruptible Power Supply.We are also surveying all other signal
systems in the network to ensure they have the sameprotections.The
system manufacturersare in the process of sending us extra spare
parts,and they are continuing to examine log datato identify root causes
of FEC and I/Mfailures.We have staged personnel to improve the
timeliness of response in the event of an outage.
Bergen Street Signal Investigation (continued)As we work to restore full
and consistent service, periodicinterruptions will likely be needed, and
we appreciate your patience and understanding that were doing everything
to ensure that service issafe and reliable.Long-term solutionsNext
month, well release our five-year modernization plan. As many of you are
acutely aware, an overhaul of the signal system is critical. The
computer-based interlocking system at Bergen Street was the first of its
kind installed in New York City, and we have gathered great learnings
over the past twelve years that are now informing our modernization plan
and our procurement requirements moving forward.Were working hard to
give New Yorkers the transit system they expect and deserve and minimize
experiences like the one many of you had on March 15. It wont be easy or
happen immediately butknow that we wont stop until we have your trust to
get you where youre going.
