General Engineering Consultant Code Charts Segment I and II
Client: National Railroad Passenger Corporation (Amtrak) Location: Washington to New York NEC Value: $184,000. (Fee) Reference: Keith Holt (215) 349-1028
Amtrak is planning to replace its current computer based CTC
and SCADA control systems in Philadelphia, New York and Boston,
known as CETC, with a modern state of technology control system
in Wilmington, Delaware. Amtrak is actively engaged in the development
of preliminary engineering documents and is planning to have
final bid documents for the new Control System by the end of
2004. These bid documents must include accurate information pertaining
to the existing signal systems' control and indication
arrangements including, data tables, RTU addresses, RTU type
and hierarchical structures among others. Gannett Fleming Transit & Rail
Systems was awarded two tasks under their GEC Contract for A/E
Services, to assist Amtrak with assembling this information for
Amtrak's Philadelphia and Metropolitan Divisions. The first
task which is referred to as "Code Charts I" documented
existing controls and indications that are being sent and received
from the CETC system in Philadelphia, PA and the 42 interlockings
from CP Avenue to CP Holmes inclusive. This task also involved
the preparation of a single line signal layout diagrams to illustrate
the connection between the code system data and the wayside infrastructure.
GFT&RS also prepared system block diagrams that illustrate
the command and control configuration of the various systems
and sub-systems at the interlockings.
GFT&RS has finished its work for Code Charts I and has recently
started on the Code Charts II segment of this work which will
encompass the Metropolitan Division, between Croy and Hudson,
but not including Interlockings presently controlled from tower
locations including Union and Dock. Code Charts II will also
provide updated information for Penn, Girard, Mantua, Shore and
Holmes in the Philadelphia Division which were inventoried under
Code Charts I.
