MTSC's magnetic support
system can use a trackway that is simple and inexpensive to
fabricate, and easy to install. The trackway may be fabricated
in a series of short, straight segments that are joined end to end,
and mounted on or under a supporting structure. The segments
can be of a convenient length for transport and
installation.
The basic trackway configuration
includes one or more (parallel) levitation rails, consisting of
a sandwich of layers of steel and non-steel. There are
also vertical running surfaces for the steering wheels,
and horizontal surfaces for the vertical restraint wheels which
protect the vehicle from overloading of the magnets. In normal
running, the vertical restraint wheels do not contact their running
surface on the trackway, but float a short distance above
it.
At the joints between segments, the
alignment of the trackway may be swiveled to form both horizontal
and vertical curves. The levitation rails need not be
continuous across the joints. The magnetic flotation of the
MTSC system allows the vehicle to pass smoothly across moderate
gaps, without the jarring and pounding that would occur with
conventional wheels. This allows the trackway to easily
accommodate thermal expansion and guideway deflection, and
facilitates the installation process by reducing the level of
installation precision required.
There are numerous configurations of
trackway that can be used, according to the
situation. The options include top-riding and underhung
trackway, and side and center-steering
configurations.
The nature of the trackway allows its
supporting structure to adapt to the terrain and route alignment
with greater ease than is often the case with conventional wheeled
systems. It also facilitates the use of supporting structures
that are quickly and easily fabricated, transported to their site,
and installed. Such structures may even be portable, allowing
them to be dismantled when no longer needed, moved to alternate
sites and reinstalled for subsequent use. It is possible
to consider supporting structures that may be installed with a
minimum of site preparation and minimal impact to the
surroundings.
Typically, the cost of fixed guideway
transport systems is dominated by the cost of the guideway
itself. The ability of the MTSC technology to use a less
expensive and more easily installed guideway, relative to
conventional wheeled systems, is an attractive
advantage.
MTSC's trackway design can incorporate
track switches and and crossings, to enhance the operational
flexibility of the system.
