2. The Current Roosevelt Island Tramway is the Second Iteration
The original Roosevelt Island Tram was built and opened in 1976, but if you were to ride the tram today, you would be riding on a completely different machine.
In 2010, the tramway was closed for a complete renovation. Everything from the original build was replaced, including the cars, except for the three tower bases. Perhaps the most significant change from the original was the addition of the dual-haul system. With the new system of operation each car can operate independently as opposed to the cars traveling at the same time. This new system makes transportation more efficient during peak times by allowing both cars to be in the station at the same time.
