| Wong served as the
Prime C onsultant for the systems design of the 15.3-mile North-South
Line of TRAX, the Salt Lake City Light Rail Transit System. The
design was accomplished using cost-effective, proven equipment
to enable the light rail transit line to be completed within an overall $312
million budget. The systems design included traction power substations,
overhead contact system (OCS), signaling/train control, communications,
and fare collection systems.
The TRAX North-South Line alignment extends from the southern
terminus in the community of Sandy, runs within a 12-mile regional
railroad corridor through the cities of Midvale and Murray, and
proceeds north in street medians through the Central Business
District of Salt Lake City terminating at the Delta Center. The
TRAX LRT System focuses on meeting transportation needs with sensitivity
to community urban design considerations. As a result, the key
design elements include:
- Fluted catenary poles with cast iron bases and light fixtures
match the historical street lighting poles that are used extensively
in downtown Salt Like City.
- In the downtown portions of the TRAX LRT System, visually
pleasing cantilever support arms support a single contact wire
system, compatible with the urban environment.
- Balance weight assemblies to tension the overhead contact
wires are hidden from view inside fluted poles, avoiding hardware
clutter in the business district.
Modular traction power substation designs were developed to accommodate
the units in the narrow right-of-way. The design evolved from
the factory-assembled substation design concepts that Wong brought
to the transit industry in the early 1980s.
Over 12 miles of the line is along a shared right-of-way with
a regional, short-line railroad. The joint use track is utilized
from midnight to 5:00 am by the freight railroad; consequently,
the signaling/train control system is compatible with both LRT
and freight operations. Grade crossing warning systems suitable
for LRT and freight trains are integrated with traffic control. |
