There three (3) main means of transportation
for goods, which are notably road, railway and canal. It should also be noted of
air transportation which is frequently used even for such short distances as
New York to Abuja. Some goods are carried on the regular internal air services:
in other cases aircraft are specially chartered. The shorter the distance, however,
the more the chief advantage offered by air transport, namely speed is reduced.
The main reason for this is the length of time that it normally takes to
transport goods to and from airports to town centers. The growing use of the
helicopter offsets this and may result in carriage of larger quantities at
present transported by air relatively small.
Transportation involves questions of cost, speed safety, and also of
convenience and suitability for the kind of goods to be transported. As regards the last mentioned consideration, it
is difficult always to draw a hard and fast line for instance in the case of heavy and
bulky merchandise. Large quantities
of worked minerals such as clay ,
limestone , sand and of worked minerals such as bricks, tiles, lime also certain sorts
of coal , some heavy manufactured goods
and some non- particularly in cases
where the works , depots or warehouse of the consignors and consignees have easy access to the inland waterways. All
these classes of goods are in
other cases more
conveniently transported by rail, especially where railway
siding accommodation is available
at both ends of the journey. When road transport first started to come
into its own, it was thought that while road vehicles would take a great
proportion of the lighter traffic from the railways, the latter would still
retain all the heavy traffic. In actual fact goods of enormous weight, such as boilers
and ships, castings are from time to time carried by road. The bulk of this traffic
however remains with the railways as does a large proportion of medium traffic.
The great advantages of road over rail transport are that
for short and intermediate distances road transport is quicker
than rail and only one loading
and one unloading operation is s involved, transport being
from door to door. The railways have some extent overcome the handicap
of the double handling by the introduction of the container system. Even long
before there was any question of nationalization they
also recognized the
superiority in some respects
of road over rail transport and fortified
their position by acquiring the
businesses of existing road transport
companies and setting up such
companies themselves.

The table above show the
comparing the four (4) means of inland transport from the economic point of view
of the four considerations already mentioned via, cost, Speed, safety and convenience.
The table cannot be taken as being more than generally correct since whether one system of transport is in fact
cheaper or speedier or more convenient than another
in any particular case depends upon the circumstances. For a short distance
such as 20 miles road transport is without a doubt the swiftest at present but
for 100 miles air transport might be swifter. It is interesting to note that at the end of the second world war 2 when it was
proposed to bring in an
integrated charges scheme for nationalized road and rail
industries, it was expected that
road transport would
be cheaper for most goods
for distances up to about 100 miles
that for distances between about 100 and 200 miles the charges
would be approximately the same
by either method and
that the railways would be
cheaper for greater distances.
