DEPARTMENT OF TRANSPORTATION
Federal Railroad Administration
Notice of Application for Approval of Discontinuance or
Modification of a Railroad Signal System or Relief From the
Requirements of Title 49 Code of Federal Regulations Part 236
Pursuant to Title 49 Code of Federal Regulations (CFR) part 235 and
49 U.S.C. 20502(a), the following railroad has petitioned the Federal
Railroad Administration (FRA) seeking approval for the discontinuance
or modification of the signal system or relief from the requirements of
49 CFR part 236, as detailed below.
Docket Number FRA-2010-0134
Applicant: Mr. James V. Samuelson, Deputy General Manger--Safety &
Training, New Jersey Transit, One Penn Plaza East, Newark, New Jersey
07105-2246.
The New Jersey Transit (NJT) seeks relief from the 2 year periodic
testing requirements of the Rules, Standards, and Instructions, Title
49 CFR part 236, Sec. Sec. 236.377 Approach Locking, 236.378 Time
Locking, 236.379 Route Locking, 236.380 Indication Locking, and 236.381
Traffic Locking, on vital microprocessor-based systems. NJT proposes to
verify and test signal locking systems controlled by microprocessor-
based equipment by use of alternative procedures every 4 years after
initial baseline testing or program change as follows:
Verification of the Cyclic Redundancy Check (CRC)/Check
Sum/Universal Control Number (UNC) of the existing location's specific
application logic to the previously tested version.
Testing the appropriate interconnection to associated
signaling hardware equipment outside the processor (switch indication,
track indication, signal indication, approach locking (if external)) to
verify correct and intended inputs to and outputs from the processor
are maintained.
Analyzing and comparing the results of the 4 year
alternative testing with the results of the baseline testing performed
at the location and submit the results to FRA.
All records of locking tests will identify the method used
(i.e., conventional, baseline, or subsequent alternative method).
Applicant's justification for relief: Many of NJT's interlocking,
controlled points and other locations are controlled by solid-state
vital microprocessor-based systems. These systems utilize programmed
logic equations in lieu of relays and other mechanical components for
control of both vital and non-vital functions. The logic does not
change once a microprocessor-based system has been tested. Locking
tests are documented on installation.
Interested parties are invited to participate in these proceedings
by submitting written views, data, or comments. FRA does not anticipate
scheduling a public hearing in connection with these proceedings since
the facts do not appear to warrant a hearing. If any interested party
desires an opportunity for oral comment, they should notify FRA, in
writing, before the end of the comment period and specify the basis for
their request.
All communications concerning these proceedings should identify the
appropriate docket number (e.g., Waiver Petition Docket Number FRA-
2010-0134) and may be submitted by any of the following methods:
