Recent improvements in air transport
1. The
increase in size of aircrafts makes it more economical to run them.
2. Improvements
to design, e.g. the fuselage and engine improve fuel efficiency and reduce fuel
costs. Larger doors, from the tail and nose reduce loading and unloading time,
thus save labour costs. Cargoes of larger size can now be transported by air.
3. With
technological improvements, aircrafts are now faster and more reliable. More
safety features in aircrafts, e.g. the 'auto-pilot, improve landing and
navigation of the aircrafts.
4. With
an increase in the number of airports and better handling facilities now
available in most airports, less time is wasted.
5. Nowadays,
special lightweight containers are available for air cargo.
Recent Improvements in Rail freight
Transport:
1. Many
loss-making lines and stations have been closed.
2. Diesel
and electric locomotives, which give a faster service, are now being used.
3. The
signaling system and rail tracks have been improved.
4. The
freight transport is now operated by computer.
5. The
express parcel delivery by passenger train has been developed.
