Project Scope
NJ TRANSIT replaces components of the rail system regularly, based on each component's respective life cycle. "State of Good Repair" is achieved when the infrastructure components are replaced on a schedule consistent with their life expectancy. For example, NJ TRANSIT expects track to last 35 to 50 years before requiring replacement. Given NJ TRANSIT's 535 miles of main line track, on average 53,000 ties and 13 track miles of rail must be replaced annually in order to maintain "State of Good Repair."

Structures - NJ TRANSIT's rail system includes more than 600 bridges as well as various retaining walls, catenary and signal structures. NJ TRANSIT inspects bridges and other structures to ensure safety of operation. However, NJ TRANSIT has a backlog of bridges and other structures overdue for replacement.

Electric Traction - Many of NJ TRANSIT's rail lines operate with electric locomotion. The overhead catenary wire and power substations must be maintained to run electric service optimally. Except for certain areas such as main messenger and auxiliary wire on the Morristown Line, electric traction systems are at "state of good repair."

Signaling - Signaling encompasses grade crossing warning systems and train operation signals, as well as switching and interlocking signal devices. Maintenance of signalizing systems is essential for safe operation of the railroad. NJ TRANSIT anticipates its signaling systems will achieve "state of good repair" by 2008.

Work Equipment - In order to properly maintain the rail system, NJ TRANSIT allocates resources for work crew equipment such as backhoe, cranes, excavators and other small equipment. NJ TRANSIT also maintains and equips rail, tie and surfacing work crews. Work equipment is currently at "state of good repair."

Track - NJ TRANSIT regularly replaces and upgrades track, ties, switches and grade crossings to maintain "state of good repair." Track systems are currently maintained at a "state of good repair."

Project Cost
Once "state of good repair" is achieved the cost to maintain a state of good repair on the existing rail system is approximately $67 million annually in 2005 dollars. Until "state of good repair" is achieved, additional funding of $20 million per year is required for the existing system. As the system is expanded, and with inflation, additional capital funds will be required to maintain the railroad at a state of good repair. $33 million is needed each year to bring NJ TRANSIT bridges up to "state of good repair."
