- Designing
a vehicle's size, there are three axes that come into play:
(1) longitudinal axis, or length. Example of extending the
longitudinal
is adding additional length to
a bus, as in the articulated bus.
(2) vertical axis, height, is seen in the double deck bus and rail car.
(3) the final axis is the horizontal, or width. Until now,
no transit system
addressed increased vehicle width as an advantage. The widest
transit vehicle in the U.S. is BART's 10.5' commuter rail car. Why?
Because all transit systems built today have the Center of Gravity
between the wheels and this, in turn, for a wider vehicle width
would require wider acquisition of urban land, wider bridges, greater
cost, etc. In contrast,
the FasTran designs and controls the Center
of Gravity outside the wheels and cantilevers the vehicle into the
"free-air-space" from a relatively narrow guideway.
- The vehicle's Center of Gravity (CG) is defined and controlled as no
other surface transit system. The design
defines the CG range and
maintains the CG range outside the wheels points of contact with the
guideway. The empty CG is loaded with a designed factor
which
also
aids passenger comfort. The main support/drive wheels
are steel and roll on welded steel rails. The balance wheels
roll on smooth sheet steel. The result is a smooth
passenger ride
through all vehicle speed ranges.
- With CG outside the points of
contact, the result is a cantilevered monorail.
A system that replaces conventional transit systems’ rectangle
support with the FasTran’s
patented triangle support system.
When incorporating this design, the results are the world’s
widest-bodied, highest capacity, premium comfort transit
system for urban and special use areas.
- Why is the triangle a better structure than the rectangle?
Because
of the unique force/structure, the triangle design produces
perpendicular (right angle) relationships between the wheels
and the running surfaces. At the same time, this design
defines the enlarged Center of Gravity and controls
the vehicle’s CG range and movement.
- The guideway is constructed in a controlled environment, off site.
The outer frame is made of steel and concrete
with rails are
attached. The rails are
constructed using laser aiming
and measuring. The guideway is trucked down the
freeway at night and lifted to one side of two supporting
T-columns. Lastly, the two guideways are "cradle & braced"
together to counter act the vehicle's torque input.
In urban
centers where structures
limit bi-directional guideway, single
guideways structures are used. - All guideway and vehicle forces are "boxed".
- The switch uses computer driven robotics for switch movement
and control. The actuation is "4-seconds" fast,
open
to closed, and provides
system designers unlimited
switching functions and variants. - FasTran’s wide-bodied benefits &
features are targeted to attract
a new class of commuter, the middle and upper income
business person, who desires a better quality and
higher class of the transit ride. FasTran also provides
this type of rider the ability to reclaim personal time
once lost when using conventional automobile commuting.
