Roosevelt Island Tram Modernization Project

Project Benefits

The current "single haul" system is comparable to the operation of a mechanical clothesline because both cabins must travel along the cable loop at the same time, with each cabin ending its trip at the opposite side. As a result, both cabins must be operational during non-peak travel times and both must be taken out of operation to perform maintenance on any one part of the system. In contrast, the dual haul system being installed, which enables the cabins to travel independently, will allow for greater scheduling flexibility during both rush and off-peak hours.  It will also permit maintenance on one side while the other remains operational. Furthermore, an automatic rescue system will use auxiliary power sources in the case of an outage to return cars to the nearest station, eliminating the need for rescue equipment.

  • Increased reliability.

  • Service life extended 30 years.

  • Each tramway line can be operated independently in event of: malfunction, preventive maintenance, rush hours and other peak and off-peak demands.

  • Integrated rescue system will ensure that in the event of a malfunction of any component or power failure, the cabin cars will be brought back to the nearest station using redundant power and motive systems, avoiding high level emergency rescue operations.

  • Reduced downtime for maintenance and repairs: one lane can be shut down for repairs while the other lane can provide uninterrupted service.

  • Reduced maintenance and operating costs.

  • Improved quality of travel, providing a smoother ride under high winds due to new wide track rope gauge.

  • State-of-the-art technology brings higher levels of energy efficiency.
