- Political differences/ differences/ different political ideologies/ political instability among African countries hinder efforts to construct railway line to link them
- African countries produce similar goods hence there is limited trade between them. ( this does not warrant construction of railway lines)
- Railways are expensive to construct/ most African countries are poor/ inadequate capital and hence expensive to construct/ expand
- Parts of Africa are unproductive so it would be uneconomical to construct railway lines
- African countries have railways of different gauges, which make it difficult for them to join
-
- Physical factors which favour the location of settlements

- Availability of land/space
- Nature of relief
- Suitability of climate/good rainfall
- Absence of pest and diseases/health environment fertile soils

- Difference in functions betwenn New York and Nairobi cities
Nairobi New York It is an inland/dry port
It is a national capital
It is a regional commercial centreIt is a sea port It is a state capitalIt is an international commercial centre
- Physical factors which favour the location of settlements
- Compare the ports of Mombasa and Rotterdam under:
- Transport to the interior - Mombasa relies on road, railway, air and pipeline to the interior while Rotterdam has in addition, river Rhine and canals Rotterdam is a major transshipment centre.
