Conrail’s operation in New Jersey requires manning
of movable bridges to comply with various marine
regulations
• 1/3 of former Conrail’s movable bridges were located in the
Shared Assets allocated territory
• 10 were in the New Jersey area
− 6 bridges service pleasure craft only
− 4 bridges service commercial shipping
− 6 bridges utilized BMWE craft (15 positions)
− 3 bridges utilized TCU craft (13 positions)

Conrail’s operation in New Jersey requires manning
of movable bridges to comply with various marine
regulations
• Code of Federal Regulations mandated specific operations
for all movable bridges
– Hours of operation based upon those requirements
• Coast Guard monitors bridge activity and Conrail’s
compliance with regulations
• Increasing marine activity coupled with bridge operator
attrition presented an opportunity to get serious about
automation of movable bridges at Conrail

4 movable bridge candidates were identified in
2000 for automation that appeared to have the
greatest potential for success
• Secondary and industrial tracks
• Marine activity was limited
– CFR did not require 24/7 operator presence
– Pleasure craft only
– Bridges closed to marine traffic during winter months
• Increasing complaints from boating public caused the Coast
Guard to consider expanding hours of operation
– Increasing overtime requirement to meet demand
– Accelerating need to hire and train new bridge operators
• Successful automation would be a win-win for all parties
concerned

Between 2000-2003, new technology interfaced with
old infrastructure to allow for the automation of
movable bridges on Conrail
• Each bridge had unique challenges to solve
• Each automation solution was tailored to the specific
marine and train operation at that location
• Electrical, mechanical, and signal modifications were
necessary to support bridge automation
• Automation plans were submitted to the Coast Guard for
their review and approval for each bridge
• Concurrently, Conrail finalized design and requested
authorization for capital expenditures (continued)

Between 2000-2003, new technology interfaced with
old infrastructure to allow for the automation of
movable bridges on Conrail
• In the end, 3 different applications were chosen for bridge
control:
– Microwave link path between one bridge and another 24/7
manned bridge
– DTMF radio control allows train crews to operate three bridges
– Remote control by Mt. Laurel Train Dispatch Center was
the best solution for another location
• Upon completion, the automated bridges were bulletined
in service and the Code of Federal Regulation for
operation at each location was modified

Conrail enjoys the on-going benefits and
efficiencies of movable bridge automation and
continues to explore future opportunities
• Each bridge automation projects produced a significant ROI
• Re-deployment of the existing bridge operators and
reduction in future hiring requirements
• Elimination of train delays due to operator availability
• Reduction in complaints from boat owners regarding
bridge openings
• Improved relationship with the Coast Guard

Conrail enjoys the on-going benefits and
efficiencies of movable bridge automation and
continues to explore future opportunities
• Building on these successes, Conrail is reviewing the
cost and benefits of our remaining, more
challenging future automation projects

The success of each of the projects was primarily
due to the interaction and cooperation of many
agencies and organizations
• Conrail’s Communication & Signal and Bridges & Building
Departments
• Conrail’s Labor Relations Department
• CSXT and NSC for their support of these capital projects
• Hans J. Heidenreich, Heidenreich Associates, Inc.
• North American Signal, Inc.
• United States Coast Guard
• Various marina owners
