The new tram
features a remade operating system - a "dual
haul" mechanism. The previous "single haul"
system was comparable to the operation of a
mechanical clothesline because both cabins had
to travel along the cable loop at the same time,
each cabin ending its trip at the opposite
side. As a result, both cabins had to be
operational during non-peak travel times and
both had to be taken out of operation to perform
maintenance on any one part of the system. In
contrast, the new dual haul system enables the
cabins to travel independently, allowing for
greater scheduling flexibility during both rush
and off-peak hours. It also permits maintenance
on one side while the other remains
operational. Furthermore, an automatic rescue
system uses auxiliary power sources in the case
of an outage to return cars to the nearest
station, eliminating the need for rescue
equipment. Specifically, the benefits of the
new system include the following:
-
Increased reliability because when one car
is out of service the other can continue
carrying passengers.
-
A service life extended by 30 years.
-
An integrated rescue system that, in the
event of a malfunction of a component or
power source, ensures the cabin cars' safe
return to the nearest station using
redundant power and motive systems, avoiding
high level emergency rescue operations.
-
Reduced downtime for maintenance and repairs
again due to the ability of one line to
continue operating while the other is
serviced.
-
Greater efficiency in energy use,
maintenance time, and operating costs.
-
Improved quality of travel, providing a
smoother ride under high winds due to new,
more stable, wide track rope gauge.
