The city of Portland, Ore., has begun operation of a spectacular $57 million aerial tram
that runs 1100 yards from the city’s South
Waterfront district to the Oregon Health &
Science University (OHSU). To ensure its reliability against problems with the electrical
grid, the tram has been equipped with two
independent diesel-hydraulic power sources.
A VERY HIGH PROFILE JOB
Portland, Ore., aerial tram relies on diesel engines to back up hydraulic and electrical systems
BY PETER MARSH
Earlier this year, the city of Portland, Ore., unveiled a high-profile transit project — about
500 ft. high at its highest point.

The city has begun operation of a
spectacular $57 million aerial tram
that runs 1100 yards from the city’s
South Waterfront district to the Oregon
Health & Science University (OHSU).
This is considered to be only the second use of an aerial tram in an urban
area in North America, the first being
the Roosevelt Island Tramway that
runs to Manhattan, erected in 1976.
The Portland Aerial Tram was built to
provide a fast pedestrian link between
OHSU’s crowded hillside campus and
its new Center for Health and Healing
