The types of transportation systems
most suited to any tunnel are related to its length. If the tunnel is short,
there is little need for manriding, and materials can be moved by hand or
with the muck haulage equipment. A long tunnel will require some form of manrider,
and special materials may need a dedicated carrier to avoid interruption of
production or damage during transport. Cost and disruption factors have become
increasingly important in recent years, and there has been a trend towards
modular systems that provide a multi-function role. For instance, a locomotive
can provide a manriding facility without interfering with its prime function
as a haulage unit. Other, more complex, systems provide versatile and sophisticated
cassette units that can be rapidly mounted on the prime mover. Also required
for transport in tunnels are conveyors, hoists, cranes, loaders, carriers,
locomotives and rolling stock, and all manner of railbound, monorail, and
trackless equipment.
